Warning: Running a Marathon Can Seriously Harm Your Health

by Paula Jager FitnessComments: 226

Have you ever noticed that the marathon runners in the Olympics look like concentration camp victims?

Have you ever wondered why marathons are considered “healthy” in our society yet the first man that ever ran one collapsed and died immediately after?

Yeah, and Pheidippides was fit too, likely selected for his job as a herald due to his speed and distance running ability – not some ancient Greek version of the modern couch potato.

While life may be a marathon your training program should not be. Running a half or whole marathon or competing in a triathlon are all admirable goals. But there are many dangers associated with excessive endurance training.

Dating as far back as the 1970’s, the misconception of mainstream training philosophies that 45 minutes to an hour or more a day of intense aerobic activity has led to an overtrained, unfit, immune-compromised exercising population.

Man was not designed for movement at a chronically sustained high intensity aerobic pace. We’ve all seen it in the local globo gym–day in and day out, week after week Jane and John plod away on the treadmills and ellipticals or pedal themselves into exhaustion in spin classes. It has done nothing to shed the extra fat on their butts and guts let alone tone them. I have never been impressed by any of these results.

 What exactly are the problems caused by training for long periods of times at high intensities such as what occurs during a marathon? Several things. . .

  • Debilitating osteoarthritis . . . at young ages
  • Tendonitis and other repetitive strain injuries
  • Recurrent upper respiratory infections
  • Increased oxidative damage (free radical production)
  • Decreased fat metabolism
  • Susceptibility to injury
  • Loss of bone density
  • Depletion of lean muscle tissue
  • Coupled with the common high refined carbohydrate intake promotes a dangerous level of continuous systemic inflammation.

Eeek! Sounds like a workout gone very bad to me and the sad part is the intentions of this exercising population are good; they are doing this all in the name of “health.”–they are not out to destroy it.

Aside from the disastrous results mentioned above why is high intensity aerobic pursuit such a dead end? One reason is the high level of carbohydrates consumed needed to sustain this activity leads to chronic inflammation. You’ve all seen it–Sally and Johnny are running a 5 K so they load up on a big bowl of pasta the night before and chow down on bagels and juice immediately after their 36 min 5 K. Type 2 here we come.

But quite simply because man was not designed (evolved) to work like this; we have 2 primary energy systems to power our muscles. The first relies on the slow burning of fats keeping us fueled while at rest yet allowing for continuous low level aerobic activity such as walking, gardening and day to day physical tasks. Fat is a very efficient fuel, stored and burned easily and cleanly when lots of oxygen is present

Our second primary energy system that evolved is an ATP fueled system that allows us to do intense loads of work in shorts bursts. It is our high octane fuel. Think of the woman that lifts a car off her child trapped beneath it. Or the person that sprints after a mugger to get their wallet back. In other words all out effort for fewer than 20 seconds; flight or fight and life or death tasks and situations.

Our energy systems are far more complex than that but it boils to the fact that we were evolved to either move slowly and steadily or briefly and fast and we become both healthier and stronger by exercising and living in this manner.

All being said there are still people out there that want to run a half or whole marathon or a triathlon and there is a better and smarter way to train for it while avoiding the negative risks mentioned above. The days of logging mileage in excess of 20+ a week are rapidly becoming archaic. And so is the weak and skinny appearance of the stereotypical endurance athlete.

Many are finding that by incorporating strength and conditioning workouts into their training routine along with shorter more interval based training they are improving speed, power and overall performance along with reducing injury potential. Not to mention having a lot more free time, fewer injuries and no long term scarring/damage to the heart.

This has been hotly debated but well documented in the past several years. Leading the pack in the defense is CF Endurance’s Brian MacKenzie www.crossfitendurance.com. His training has many top level endurance athletes setting personal records far above past efforts with a dramatic reduction in training time and mileage.

Fitness can and should be achieved without the need for pounding the pavement for miles on end, a huge daily time commitment, and a long list of extreme risks to health both short and long term.

      The misinformation here in incredible. 1) With proper diet/ running form/ injury prevention, all of the injuries you listed can be prevented (btw I have never heard of running causing an upper respiratory infection). 2) You don’t need lots of carbs to run for long distances- fats and proteins burn better. 3) “20+” miles per week wont get you in shape to run a marathon, the pros do over 100 miles a week and are perfectly healthy. 4) crossfit and short high intensity intervals won’t increase your endurance very well either. Humans evolved to run, get over it

        I agree completely. His two main energy scources are completely incorrect. ATP’s first choice is aerobic (with oxygen). The body uses oxygen until about 75% of maximum heart rate is reached. Once it’s about 85% it begines to use lactic acid because oxygen cannot keep up. But the point is that even professional marathoners do not exceed 85% of their maximum heart rate until the last 30 or so min of the race. I know a coach who has proven that anybody can run for an hour if they keep their heart rate under 170 bpm he has proven this with first time runners using heart rate monitors. You know nothing about distance training, the energy zones of the heart, and your statement that we have not evolved to run is completely laughable. Do you realize for 100 million years humans hunted without weapons? This is called persistence hunting. Persistence hunting is when one keeps an animal moving until it overheats and collapses, humans are made to run, from cooling devices like arm and leg hair to our perfectly shaped feet and highly effecient trot. This article was written by people who profit from the misinformation they provide. Running is a fantastic excercise, and a collaigent cross country and track athlete and a math/biology major I can assure that this article is bologna!

    Very interesting. I ran extensively in high school and suffered a few injuries but have not run so intensely since…however many of my friends have done marathons and 1/2 marathons and at this point a 1/2 is the farthest distance I’d consider.
    The other night I was watching a TV show on USA and a character was a “marathon runner,” but my husband & I noted that she was not skinny enough to be a typical marathon runner. You could actually see flesh on her body and she wasn’t just skin & bones (not that all marathoners look like that, but it seems many of the professionals do)!

    I think Paula is wrong on this one. I think we are definitely “evolved” to run long distances (as in following game for the hunt.) The problem really only comes when we turn it into a race and keep trying to do it faster and faster. It may well be true that professional marathon runners are emaciated, because they are trying to win. However, I know many marathon runners who are not pro’s, and they are the very image of fitness. Strong and sleek and glowing with good health. Sarah is a big fan of the anecdotal evidence, and the anecdotal evidence for running as a healthy form of exercise is abundant. Even running longer distances.

      Chasing game was normally done on the back of a horse. Where on earth did you learn your history? I live in buffalo country and believe me, they weren’t hunted on foot. :rolling eyes: We attend (I ride) in the Custer State Park Buffalo Round-Up every September. We aren’t even hunting them and it can be dangerous.

      Trapping and fishing were probably the only types of “hunting” not done on horseback because a quick get-away wasn’t usually necessary.

      Most of the runners I know are now suffering with joint problems. It’s a fact, not an anecdote. Sarah, this is just one of those things people have to live long enough to experience, I think, because judging from the amount of negativity being posted here, I can see you are dealing with younger, more inexperienced folks. Oh well, live and learn. And they will.

        This comment about horses and trapping reflects a gross misunderstanding of both evolution and also the VERY limited amount of time in human history during which humans have participated in such activities as domesticating horses and using traps to hunt.

      Running is very healthy. It’s when people overdue it and spend excessive time at a high intensity. When man went hunting his “chase” for game was nowhere near the distance covered in a marathon. It didn’t take 26 miles to kill dinner; more like a couple of hundred meters or less. He may have walked quite a distance, getting hours of low level aerobic activity but the intensity was limited to short burts of speed followed by recovery.

        Have we forgotten that humans hunted on foot before ever taming horses? Have we forgotten that the glutes are the strongest muscles in the body? Or how about we sweat better than any mammal (most animals with fur must pant to keep cool) in the world and are able to keep our bodies cool with the least amount of effort? Humans are made to run. I do agree though that intensive training in any activity for long periods of time w/o adequate rest and nutrition are damaging. All of us could get out and run 20-30mins a day and be healthier for it. Aerobic activity is a must for optimal health.

        This is false, persistence hunters would run at low speeds for 15-20 miles in the peak of the day before catching their game. Running is much more efficient than walking, our bodies are built for it.

        Next time you write an article with the intent of drawing people to crossfit you should try espousing the strengths of your own fitness style instead of improperly bashing on another. All of the negative effects you listed would be caused by improper training or inadequate nutrition. You could apply the same train of thought to crossfit and come up with an equally scary list of effects.

      The book Body By Science explains this topic quite well. Our ancestors did partake in long, monotonous, moderate intensity activity. Our body’s metabolism is uniquely designed to respond to high intensity stimuli. The book also shows some interesting studies showing the health issues associated with endurance athletes.

      Yes, but before busting this “myth” there was another myth and preconceived ideas busted. The one that told us we were not able to run long distances, the one that told us we would died or get hurt, the one that told us it would be impossible. Granted, ultra endurance events is not for everybody, and it doesn’t have to be. If you want to shed some pounds or be healthier, you don’t have to be and endurance athlete!!! it is not a requirement! But if that’s something that you find inspiring and want to try it…. WHY NOT!? with proper training, and the right mental attitude it can be done avoiding injuries and damage to our body, and if you find out that’s your passion GO AHEAD!!! take care of your body and pursue your goals.

    I would say that giving birth is definitely NOT like a marathon. There are natural resting phases after every contraction (with a nonmedicated birth at least) which you do not ever have in a marathon.

    I realize running marathons often are compared with long-distance hunting of animals but from what of seen of animals stalking their prey it’s not usually a continuous trot/run. It’s probably closer to interval training with speed variations and occasional breaks.

      No it would not be. The human body is made to run efficiently, walking would be a waste of energy. After about 8 km/hr it becomes more and more energy efficient to run than to walk. Not to mention the forces exerted on your body from the acceleration and deceleration of the interval training you theorize would create much more impact forces on your body vice a steady trot which in the long run.

      What about all the marathon runners that drop dead? Every marathon it seems, at least 1 person dies and several go to the hospital. Many also have permanent scarring to the heart muscle which you couldn’t tell by looking at someone. I seem to remember Mercola had an article on this recently how the heart muscle is permanently scarred by endurance training.

        What about all those people who drop dead from sitting on their ass? (!!) People die or have serious injuries because they didn’t train properly or pushed themselves too hard not because of the magical 26.2 miles that they want to run. In this day and age I cannot *believe* someone would be discouraging people from a form of physical activity that CAN be safe and healthy. I just wonder if you have a hat somewhere with a bunch of ideas that 95% of the population things are good things… then draw out of it and set out to prove everyone that they are wrong are you are right.

          Please read the entire post as it doesn’t discourage running. Please see Paul’s comment below which hits the nail on the head.

          By the way, plenty of well trained, well coached marathoners drop dead (at young ages too like in their 40’s and 50’s) after running for years with seemingly no problem. Just because most people believe something to be true doesn’t make it true. I like how Paula dismantles the marathon sacred cow in this post. People need to realize that this type of exercise is dangerous and not healthy for the long haul.

            But you know…lots of NON-marathoners also drop dead at young ages… Sometimes people just die.

            I actually don’t see too much wrong with training and running a Marathon. What does disturb me intensely is the people who run one or two a month… to collect a medal. I mean really….we are adults here. They don’t train well, and put themselves at fairly big risks to their health, all for a shiney piece of metal?

    I’ve run several marathons, and done 6 Ironman triathlons – I am far from emaciated, very muscular, and never had health problems from participating in any of them. My doctors credited those activities with my drastic improvement in asthma as well – from very medication dependent with lots of asthma attacks to virtually med free and a much higher lung capacity than normal, let alone normal for an asthmatic. I’ve enjoyed many of your posts, but I’d have to disagree with this one as well.

    Have you seen ultramarathon runners? They’re not emaciated in the least for the most part! They’re often quite sturdy-looking … and they *far* exceed the measly *26.2* of a marathoner. (As a note, I recently began my running journey a few months ago. I’ve completed two 5Ks and was working towards a 10K. I don’t think marathon runners are Weenies 😉 ). I think a method of running is also important. There is a method called the Galloway method (formulated by Jeff Galloway) that is based on run-walk-run, inserting walking breaks into a run to keep you fresh. This bit of rest makes a lot of sense I think.

        Thanks Sarah,
        I think if we would stay busy doing all these daily type activities we would have less weight problems. I am really trying to do this. I will also add the push hard, rest and see what happens. Personally, I can’t exercise to the point of exhaustion anyway. I would be in bed for 2 days. 20 yrs ago I got an autoimmune disease that affected my joints and lost my kidneys 13 yrs ago from it..I agree that too much hard and long exercise (marathon running)can be risky.. So glad I have found the real food “way” of eating. I feel so much better. My joint problems are better. No doubt I caused my problem by the way I ate yrs ago.. the SAD diet.

    People can drop dead during most any activity, I don’t think marathon running causes death. People have heart attacks just sitting on the couch, or driving to work, or playing golf.

    I just ran my first marathon this year. I have run several half marathons and 25ks. I am not skinny and I do not look emaciated on any part of my body. I cross train and get regular chiropractic adjustments and I have been injury free. I feel strong physically and mentally when I run regularly. I have not had a cold or flu in many years. I am one of the few runners I know who fuels with high protein and quality fat before and after a run. Unless I’m running for more than 1.5 hours, I rarely need more than plain water and/or coconut water. I stay away from all the sports drinks and artificial stuff.

      Body type is going to determine whether you are skinny running marathons. Some folks will never be skinny no matter what. It is very telling that marathoners at the top of their game look horrible and emaciated. Folks who don’t have this body type could never compete in marathons at the highest levels.

      Look at other sports that are interval training based rather than endurance training.

      Tennis, soccer, short sprints and medium distance runs .. these people look AMAZING at the top of their profession.

        I’d have to agree with the article, in my opinion. Of course, that the marathoners coming to the defense of their sport doesn’t surprise me at all, and they have the right to their opinion (even if they have a “don’t confuse me with the fact” attitude). Well, 2 days ago, at the Chicago marathon, another sad death. Typical comment is- Oh , he must have had an “undiagnosed” condition. That’s almost always the response to these type of deaths. The other response might be, well he/she hasn’t trained enough. Well folks, I’d guess that it’s not an undiagnosed condition, AND, in fact, that those that train very heavily are probably in even worse shape- BECAUSE it’s the CHRONIC inflammation of continous training, possibly coupled with the fact of trying to beat your best time, that causes the death on the actual day of the marathon. Relatives of the dead marathoners seem to frequently say- “he/she was in the best shape of their life”… Oh really, how can you be in the best shape of your life and dead at the same time? It’s an INCORRECT assumption, that just because someone can run for a long while without stopping, they are in great shape. All it means is that they’ve trained their body to run for a long while…you can’t assume anything else other than this.

      You are absolutely correct My husband is a Sports Nutritionist and endurance athlete coach (cycling & track and field). He believes that nutrition is very important for endurance athletes. Many of these types of athletes read the literature and eat diets that are high in processed carbohydrates. Although these diets work to replenish depleted glycogen storage. They do very little to compensate for the catabolic nature of the oxidative energy system that breaks down fat and muscle proteins for conversion to glucose and subsequently ATP. Furthermore, the body will release cortisol as product of the training stress that breaks down muscle and converts it to glucose in the liver. This is why endurance athletes require high amounts of protein and fat in their diet. Unfortunately most are missing it.

    I hafta tell ya’ll – – one of my clients teaches a spinning class. Now, I’m from a different generation than most of my clients, keep that in mind. When she said spinning, I thought she meant with a spinning wheel – you know, like quilting or sewing type spinning of yarn. :slaps forehead:

    But the really funny part is that this girl is quite a bit overweight herself, yet she is “teaching” this class? I can only imagine her clientele. If this spinning idea was so great, how come this girl is still so overweight?? She teaches the class three nights per week. I’ve known this girl for a little over two years and her weight hasn’t budged one bit up or down since I’ve known her.

    The other funny thing is that her husband is a marathon type runner (although I don’t think he’s participated in any) and he looks, physically, on par with the guy in the first photo above (from Finland or whatever it says on his shirt). Skinny as a rail, all bones, and looking very anemic and undernourished.

    She is short and heavy – he is quite tall and super-skinny. What is supposed to be healthy about either of those body types? Not a dang thing from what I can see just from this one couple.

    Me, I eat WAPF as much as possible and I probably have 15 pounds I don’t need, but I am not 20 anymore, and I feel pretty good most of the time considering I had two medical issues to deal with before I ever started WAPF. I grew up eating a very healthy WAPF-type diet (grew up on a farm with little store-bought food) but of course in my 20’s and 30’s I ate low-fat and yada yada because that’s what I thought I was supposed to be doing (thank you Uncle Sam for all the misinformation over the years). When I started feeling crappy I knew it was time to talk to Mom! She told me my body needed nourishment from real foods and I listened because I knew in my heart she was right.

    I am glad that you brought up this intersesting point. I have always been shocked by the appearance of marathon runners. I remember two women crossing the line at the Greek summer Olympics and how they shook and were horribly dehydrated from the heat. This, along with their frightening thin bodies, made sure they looked exactly like concentration camp victims crawling along the ground and I remember being troubled by it. I know this is controversial, but especially in women just a lack of body of fat is contrary to health. While I am not a “fat-vocate” I certainly know that fertility is a function of feminine health and when fat drops too much, women are infertile. This indicates a health problem.

    It seems many of the people here who are arguing against the “overtraining” idea are missing the point. The author is not saying running a marathon or training to run one is ALWAYS BAD. Those of you saying “hey I run marathons but” are actually supporting her point – you mention interval training, not being emaciated, etc. You are training in the way she is saying is the BETTER way. One of you said “I don’t carbo load” – well that’s great, you are already following the author’s advice and hey look…it’s working great for you!

        Paul hit it spot on. While I have no desire to run a marathon some people do; done so with the proper diet and training and not in excess it can be accomplished without ill health effects. While many “professionals” are too skinny, a lot of amateurs are too fat. It’s the lack of strength and interval type training coupled with excessive carboydrate intake.

    Obviously this isn’t true for every person who runs a marathon..but it can be for some. I have a friend who I would consider addicted to, not only marathons, but excercising. That’s all she does, she has let go of all her other interests and spends less time with her kids…just so she can excercise. She had a baby 3 weeks ago and is already back into it hard core…and I don’t think that’s quite enough time for your body to recover. I think it just becomes an obsession, and that’s when it’s dangerous.

    As a recovering anorexic/bulimic from my younger days, (15 years wasted!) I can attest to the validity of this article. It is HIGHLY addictive to continually over-exercise and live in the “endorphin moment!” It has taken me years to get back to normal, with lots of twists and turns. The real moment of truth came when my sweet little daughters began worrying about their weight. It absolutely repeats itself in the next generation if you aren’t totally honest about why you exercise. Taking care of our bodies is a very good thing, even commanded by God. (He really does want what is best for us!) Moderation is key. I knew there would be some flack about this subject. Many aren’t ready to stop and look at whether or not they are addicted to the highs ( deceptive feelings of power) from this type of behavior. Thanks again Sarah! It is so good to get it out there and talk about it! Helps all of us!

    Please show me real hard data on how marathon training/running causes the following, and I quote:

    Tendonitis and other repetitive strain injuries

    Recurrent upper respiratory infections

    Increased oxidative damage (free radical production)

    Decreased fat metabolism

    Susceptibility to injury

    Loss of bone density

    Depletion of lean muscle tissue

    Coupled with the common high refined carbohydrate intake promotes a dangerous level of continuous systemic inflammation.

      Only a portion of your quote is correct. I did not say nor imply that “marathon training/running” causes the above conditions but that “excessive endurance training” or “movement at a chronically sustained high intensity aerobic pace” is well known to lead to those conditions. I am talking about people that are logging 30-90+ miles a week, over and over a period of time. Cumulative damage prevails.

      A few quick Google searches should pull you all the “very real hard data” you desire. And as for “high refined carbohydrate intake promoting systemic inflammation”, try reading Taubes book, Good Calories, Bad Calories. Lots of hard data there.

    I’m a new runner (okay, more of a jogger) and I just wanted to address this statement made by Paula: “Aside from the disastrous results mentioned above why is high intensity aerobic pursuit such a dead end? One reason is the high level of carbohydrates consumed needed to sustain this activity leads to chronic inflammation. You’ve all seen it–Sally and Johnny are running a 5 K so they load up on a big bowl of pasta the night before and chow down on bagels and juice immediately after their 36 min 5 K. Type 2 here we come.”

    I’ve been on the GAPS diet the whole time I’ve been running (and a bit before) and have had no problems whatsoever with energy. I’m only “training” for a 5K so it’s not like I’m running the huge marathons, but it is possible to eat well and still run.

    And the ToughMudder looks awesome. I don’t have time to train for the one closest to me, but it looks like something my husband would love to. I’m interested in seeing your training schedule. Maybe we’ll plan for it next year!

    Lol this is hilarious. Of course elite runners overtrain to a point that is likely not great for long term health, as do elite athletes in pretty well every sport. However, to the typical recreational runner (even one aiming to run a marathon) she is preaching to the choir and saying nothing new. I am a runner and belong to several running communities online and in real life. We ALL cross train. We ALL use intervals in our runs. We ALL do strength training. Some of us are thin, some fat, some in the middle. The few emancipated looking runners I know I believe look that way because they are prone to that sort of body type or very disciplined dieters/exercisers and would likely get super skinny whatever thier exercise of choice.

    Also, nobody except perhaps a non-runner doing it once for fun or charity carb loads before a 5k. That is laughable. If I truly felt carb loading was required before running 5k…I’d be eating pasta almost daily…which I assure you I am not.

    This is a bold article! We all know that regular exercise is good for us. Not everyone likes the same form of exercise and we all have our own reasons as to why we exercise. Finding something that you enjoy doing on a regular basis is the most important and then the other is that you need to increase your training as your body adapts. If you overdue with any sport or exercise program you are putting yourself at risk for injury. Genetics, nutrition and hydration all play an important role in what we do and how we perform as well. I had a neice tell me she did a “boot camp” class recently and she could barely move for a few days…How healthy is that… ? I also have friends that train on a regular basis to run marathons. These ladies look healthy and most importantly they are doing something they enjoy. This article was too narrowminded and judgmental.

    After recently reading the Primal Blueprint by Mark Sisson I have to agree with many of the points Paula makes in the article . Mark was an extreme marathon runner and he suffered from most of the sysmptoms of degeneration due to excessive excercising ( the man experienced eight upper respiratory infections in one year ! ) He thought he was extremely healthy but realized that he was actually killing himself. I know everyone is different but one must analyze if all this working out is really worth it in the long run.

    I understand your point about the comparison with concentration camp victims, but not all marathoners look like the one in the photo you chose and if you compare them to photos of real concentration camp victims you will see a marked difference. I think it important to note, as someone who is related to survivors (and those who did not survive), that there is a very, very, very real difference between someone who chooses to run a marathon (however unhealthy and hard on the body) and someone who is forced to live in a concentration camp. It is a sensitive point, which could easily have been avoided in the article.

    That said, otherwise this was an interesting article.

    That is why periodization in training is important. Many self coached endurance athletes never take a break. Continued training at high intensity and high volume will lead to overtraining syndrome. A properly periodized training plan with a proper mixture of aerobic, anaerobic, and load bearing exercise is important for athletic success. I would argue also that nutrition plays a big role. Just another argument why endurance athletes should be coached properly.

    I am an avid trail runner. I love my trail, I love running alone on my trail. I like slow long runs sometimes, and when I say long I mean 6 miles…because the human body was not meant to do much more than that. All it takes is a little common sense, look at those long distance runners, they look like they’re dying! On top of it all, athletes…often…are not well nourished. They’re all about their protein and sweet electrolyte drinks, but totally don’t understand real nutrition, or how their intense workouts are not just damaging their joints, but every cell in their body with free radical damage.

    I don’t agree with everything in the article, but that doesn’t matter since it seems to have been written with intentional exaggeration to make a point, and I think the point is a good one. My anecdotal experience is this: after years of no running I decided to do a relay marathon with my family and am on the hook to run 1/4 of it in a few months. I was running running running at the gym, at home and it was pretty rough, not fun at all. And not much improvement. Then, I sprained my foot playing with the kids in the yard. When I started doing some light running a week later to get back at training I made myself take walk breaks, a lot of them. After a week I noticed a huge difference, I was enjoying running and running faster in between my walk breaks. I have totally moved over to training in an interval training style and I am NOT going back. The run run run tell you drop thing is no fun and probably bad for you too.

    The writer is off target on this article. While I am willing to believe that extensive high intensity exercise is rough on the “system” that is about where my agreement ends. Firstly, you are not supposed to train like that for endurance sports. The vast majority of your training is long slow easy mileage so that you DON’T overextend yourself, prepare your body and then you up the intensity only in the weeks before your races.

    Hundreds of thousands of runners complete marathons every year and don’t die. The numbers tell the truth here

    Millions die from Chrinic disease each year that is a direct relation to lack of exercise and proper diet.

    You don’t have to eat copious amounts of starchy carbs to compete in endurance. Sticking to low GI foods like legumes and brown rice get the job done just fine and don’t throw your Glucose levels out of wack. besides if you are burning off your carbs you are essentially just refilling the tank anyway, not overflowing it like most people do that don’t train for enduracne sports.

    This article is a good example of ” a little knowledge is a dangerous thing”.

    Being able to run a marathon is not and should not be a standard of health.

    I disagree with most of the points made here. It’s true that marathons and marathon training place lots of stress on the body, but that doesn’t have to produce these ill effects. Logging lots of miles strengthens the bones and tendons and increases blood volume when mileage is increased gradually and adequate nutrition is consumed. As long as you take rest days when you feel you need them and eat well, marathon training will only make you healthier.

    Also, not nearly all elite marathoners look like the “concentration camp victims” mentioned in this article. The picture is clearly chosen to support the article and not a realistic depiction of the typical marathoner. Look at athletes like Haile Gebrselassie, Kara Goucher and Ryan Hall. They’re certainly thin, but look pretty healthy to me. Elite marathoners are thin because that’s the body type that suits the sport most.

    You’ve left a lot of room for large discussions. Just last week during a half-marathon in NC, a 35-year-old man collapsed between the 10- and 11-mile markers, and a 31-year-old man died near the finish line. Both were taken to hospitals where they were pronounced dead. Obviously, it’s an incredible stress on the body. We hear about deaths during races but not shortly after or a week later, so we don’t know for sure the true impact. But they could just as easily have died mowing the lawn. No one knows for sure.

    I was a 3 mile a day runner for decades. I think that’s reasonable and I didn’t go fast. But, I’m not a competitive type.

    I doubt the body is made for such intensity, but I could say the same thing about cross fit. I am in the best shape I’ve ever been in (strong, flexible) and I only use 3-5 pound weights. in the classes I take. When I had a guy trainer, I sustained two injuries with heavy weights, which took long healing process. Now I’m in the best training program, and I can feel the difference.

    If someone really wanted to do something for our culture, figure out a way to keep people in after age 45 when they drop out. I’ve been in the gym for over 30 years, but I’m rare. Cross fit is specifically designed for the 20-45 age group (who is well off and can afford the $250 a month).
    Running does break down barriers of age and wealth. I’d like to see more people of all ages involved in fitness. It would be interesting to know the stats on how long a person sustains a running life style vs. a cross fit life style. Not trying to put cross fit down, but I’ve noticed that if people are into cross fit, they look at others like “we don’t get it.” I know what I do get. Consistency. The key to health and fitness is not amazing abs, it’s a consistent doable life style. This consistency I’m talking about seems to be achieved most by the running community (for whatever reason).

    Still, a good conversation, and I do agree, don’t use the “concentration camp” example. Not a good choice of words. I flinched a little when I read them.

    I started running to loose weight after being encouraged by a running friend in 2007. I lost 75 pounds by 2009 and ran my first half that fall. 2 halfs in 2010 and a tri & full marathon in 2011. It was 2 weeks before that marathon I started to become ill with horrible fatigue swollen lymph nodes. I completed the marathon but have never ran more than 5 miles since. I have spent so much money on test after test and new doctors trying to figure out what was wrong with me. When I look back at pictures I see my weight started creeping up in 2010 and 2011 when I was running more and more miles. So far have been dx with hypothyroidism, adrenal fatigue pernicious anemia, CFS. I don’t know if training for a marathon caused my problems but I think I overtaxed my body to the point that basic systems started to shut down. My diet was pretty good but i consumed a the gels and gatorade and carbs the night before. All my experienced alete running friends do or did. Also the night before the marathon we went to a pasta place and was amazed at seeing very well fit runners with huge plates of pasta in front of them. I couldn’t eat like that or I’d gain 5 pounds. Lots of people run ultras and marathons with no problems, yes. Unfortunately, I wasn’t one of them.

    What this article fails to realize is that A LOT of olympic marathoners are heavily encouraged by their coaches to maintain abnormally thin weights in the misguided belief that it will lead to more endurance (which it doesn’t). So, are these health ramifications listed in the article really the result of marathon running/endurance training or the result of long term eating disorders combined with intense training? I would go with the latter. Oh, and I’m not a runner in any stretch of the word. I hike, swim, and do a couple stints on the eliptical machine a few times a week (it’s easy on the joints), but no more than 30 minutes at a time. Generally, olympians are not doing their sports for “health” reasons. They are in to win a gold medal. They know the long term health risks of the intense training they do, and they are willing to accept the risk for the chance at a gold medal.

    A lot of assumptions being made in these comments… I trained for a marathon in my postpartum year after my first child was born. My bladder strength and control improved, I had no joint issues, and I was able to get pregnant within weeks of the race. I honored my body through the training process. I ate so well. I was so in touch with how food made me feel. I ran at a pace that worked for me. And when I crossed the finish line I felt insensible joy. I learned a lot about myself that day. I come back to that moment often to remind myself how strong I am after a life of doubting. I came back to it when I birthed my second child naturally after a long labor. The psychological benefits themselves were enough! I could go on. There are good and less good ways to do everything. Excess is always a possibility. But a marathon in and of itself, moving your body for 26.2 miles, I don’t think is inherently excessive.

    It might be the 3rd re post but some things bear repeating. “Man was not designed for movement at a chronically sustained high intensity aerobic pace.” – continue to over do and most people will at some point find themselves with the above mentioned negative effects.

    Nothing wrong with running long and slow if you enjoy it–done in moderation and in conjunction with other activities. It can help facilitate recovery and clear the mind.

    Participating in a triathlon or marathon if desired can be done with minimal damage to the body provided the training is intelligent and adequate recovery periods are factored in between events.

    The picture may be extreme and is meant to make a point but it’s most on the mark. Your training will dictate what the body will look like along with your genetics.

    This is a very broad generalization about half marathoning and marathoning. While many people have had injuries (myself included) I can tell you it is because they are either increasing their mileage ridiculously fast not having run a marathon before or are not following a proper training (that includes strength and conditioning training nor a proper nutrition plan that supports the body through the training. I just think the generalizations made about long distance running are very broad.

      There is absolutely NO evidence that shows or even suggests that people are ‘devolving’. ‘Devolving’ isn’t a thing that is possible – you, like many people, have been the victim of poor teaching on the subject of ‘evolution’. Evolution merely means that a type of organism is changing through random mutation over many generations – it doesn’t necessarily mean that the type of organism is improving through random mutation over many generations.

The finish line of a marathon trumps the finish of any WOD for some people, and to post this stereotypical generalization of anyone that runs marathons is offensive, and is exactly what gives Crossfit a bad name. I love both, but I’m tired of the holier than thou attitude that Crossfitters often project. And, to talk about the “appearance” of runners… Really? People are born with different body types, different amounts of fast and slow twitch muscles. Skinny dudes are great, if it’s natural and healthy. Chicks with bulky muscles are great, if it’s natural and healthy. And, lastly, why don’t you go run a marathon…. Before preaching about how unhealthy it is.

    Have you ever trained for or ran a marathon? Just curious. I agree with you saying that logging loads and loads of mileage on in a training program may lead to injury, most of those injuries being doing too much too soon, but running and training properly for marathons is not bad for you. I’d love to see an article about all the debilitating injuries that have happened doing Crossfit… I’ve known young people that have permanently ruined their backs from lifting WAY too much weight too soon, and further screwing up their backs from kipping on pull ups because they were trying to finish the workout faster during an AMRAP workout… You can spout out all day long how running is bad, Crossfit is bad, etc… Any type of physical activity has injuries associated with them. It’s all about being smart with training and yes nutrition. But please don’t give running, or training for marathons a bad rep. I’d love to see a Crossfit person run a 2:08 marathon like Meb did at Boston on Monday… Yea not gonna happen. You know what his pre race meal is? Pasta. And lots of it. Just because not everyone eats Paleo, doesn’t mean they are carb loading up on doughnuts or pastries either…..

      Actually I’ve run a Tough Mudder (11.5 miles); using a CF Endruance training template which worked well. I personally do not enjoy long distance running. I didn’t say “running and training properly” is bad for you should one desire to run a marathon. It’s the people that log excessively and do too many miles that end up with the negative effects and injuries.

      Any exercise program–CF and weightlifting included when done improperly or too much too soon can certainly result in injuries. Kipping pull ups should never be done before one has the strength and shoulder stability to do strict pull ups.

      You get good at what you train for. Mainstream CF is not intended for marathon runners but for general physical preparedness. A combination of the 2 can greatly benefit the distance runner saving time and minimizing injuries.

      I don’t put a “Paleo” or “Primal” label on my nutrition; I eat traditional healthy real food. And if you think a bowl of genetically modified processed wheat is healthy perhaps you should do some nutritional research.

    Just too much to try and say here. It’s not running a marathon that is dangerous. It’s wrong training methods and wrong eating habits.

      If I may add. The 25 year old is a 100 – 200 meter sprinter max. Compare him to a 400 meter specialist, and then a 800 meter, 1500 meter, etc. and you will find that he is doing what he is best suited for. 99% of people could train all they want to and never, never look anywhere close to his physique.

      You’d THINK he was 60 years old, but the truth is you just MADE THAT UP to prove your point, which means on top of being a LIAR, you are WRONG. The picture is of Janne Holmen who even NOW isn’t even 40!


      So much for your “balancing facts”. Lies can be an effective way of pretending like you’re right, but only if other people don’t have access to the truth. So be careful in your future bullshitting and good luck!

    Hello! Have you seen a marathon lately? Kara Goucher? Shalane Flanagan? These women are beautiful and not a bit scrawny. They have ab muscles and thigh muscles and lord, watching them run is like watching beauty in action.
    As a woman in her 50s who runs marathons and is training for a 50-mile race, I have to say that my body hasn’t fallen apart, I don’t look like a concentration camp victim and my diet doesn’t consist of huge plates of pasta, either. (And please–your reference about carbo loading for a 5K? Who does that? You body doesn’t need extra glycogen for such a short distance.)
    I’m think that the real reason why most CrossFit instructors probably dislike running is that it costs almost nothing! You can do it almost anywhere! All you need is a good pair of shoes!
    Yeah, not a lot of CrossFit instructors making money off of running, eh?
    P.S. There is a HUGE difference between running an 11.5 mile race and a marathon, honey.

      Kara and Shalane are scrawny and very unhealthy looking to me.

        You are either obese or used to the stereotypical American so-called healthy lifestyle, where they incorporate all the animal junk and fast foods. Look at the Asian and African athletes and people in general for a moment. When compared to the them, it is a far fetched claim to say that Americans are even close to healthy. I wonder why they are much more fit and perform way better than what you refer to as healthy. Do your own research, man was not designed for animal products.

      I’d have to agree. They have beautiful faces but it is apparent from their arms and bodies that they are underweight.

      I also agree there is a HUGE difference between a 11.5 mile race and a marathon: A 11.5 mile race is fairly damaging to your joints, whereas a marathon (and the detrimental training required to get to that level) is EXTREMELY DAMAGING.

      That’s a bunch of bull. Sure, women have big fat hips and thighs no matter what but they do start to look almost more linemen after running a lot. Their cheek bones and body start to look weird and bony with thick thighs. The truth of the matter is ALL long distance running damages your internal organs without a doubt and they were never meant to strain so long to begin with. Go on now and act like you are in shape by running then try some kettle bells and cross fit and you will see how your heart can truly pump and endure. It’s funny listening to people who run, sure it doesn’t cost anything but the fact that all runners like it when cars drive by and watch them “run” and be “in shape” in front of the world. It’s a super narcissistic excercise that says “look at me everyone! I’m running, therefore I’m in shape”.

      At age 52 and 6’5″ 190 lbs. I have since discovered that “moderation” is indeed the secret to fitness. Having completed 17 marathons between 2:58 – 3:36 in my late 30’s/ early 40’s along with an 11 hour Ironman Triathlon, and in a prior life mid 20’s to mid 30’s engaged in a cross-fit lifestyle with a 500 lb dead lift & 245 lb power clean. While I commiserate with a Runner’s “passion” … I must say the Long-Term effects of LONG distance running definitely IMPACT the joints. Now, I find myself living a life a “hybrid” fitness, casual running (under 5 miles) mountain biking (hills), swimming, and moderate kettlebell work (40 – 70 lbs) to attain short bursts of intensity- 10 minutes snatches. I guess everyone wants to “push the envelope” and get that endorphin rush…. BUT really the goal of fitness is to be FIT for the LONG-TERM …. strength, flexibility, stamina into our 70’s, 80’s and hopefully beyond. Every time I see my 93 year old neighbor walking all over town that’s my GOAL (Mobility)- NOT to be in my 60’s in a wheel chair or hobbling along with a cane due to excessive running or weight lifting. Be REALISTIC understanding our bodies are indeed FINITE …. Carpe Diem!
