The Truth About Sprinters vs. Marathon Runners

130 Comments | Training

If you’re even slightly into fitness and have been interneting on the internet for the past few years, you’ve do doubt come across the picture below.

sprinting body

To summarize the picture above:

Marathon runners = skinny, weak, no muscle, pale.

Sprinters = lean, ripped, muscular, dark and handsome.

But there are some huge misconceptions about sprinting and running which I cover below.

Running does not make you lose muscle.

This is the most popular myth that a lot of fitness pros love to spread. Their argument is that due to the long distance nature of running, you’re burning your muscles for fuel.

But there’s really no proof to back this up. When asked for proof, all anyone says is blah blah blah look at the pic above.

Dude…look at marathon runners. They’re so skinny and weak, obviously they’re burning muscle when they run.

Truth: Just think about it logically. Maybe the reason a marathon runner is so skinny and doesn’t have any muscle is because they’re not trying to build any muscle and they don’t have much muscle in the first place.

Marathon and long distance runners train for their sport and that sport is running for a very long time without stopping. For a runner, lifting weights is just time wasted that could be focused on improving their running.

Marathon runners can gain muscle…if they want

You’re right, I’ve never seen someone look like Arnold Schwarzenegger compete and win in a marathon but there’s a damn good reason for that.

Here’s what you need to know:

1) Running is an aerobic exercise and doesn’t involve the explosiveness of sprinting or weight lifting. It’s all about endurance and running for as long as you can.

2) Runners don’t try to gain muscle. Their focus is on running fast and far.

3) Train for your sport. Bodybuilders train to look as lean and muscular as possible. Sprinters train to run as fast as possible over a short distance. Runners train to run as fast and far as possible. You train for your sport so you can’t criticize a runner for the physique they have.

Pick your battles

Sprinting and running are 2 very different sports. Sprinting is usually done in conjunction with weight lifting and runners tend to be laser focused on well…running.

A person who’s running 10 miles a day will simply not have the energy to hit a heavy weight lifting session as well.

It’s not that a runner’s body lacks the ability to gain muscle, it’s simply that runners don’t try to gain muscle. It’s counter-intuitive to their goal.

Also note, runners tend to have a diet that is much higher in carbs and lower in protein, so once again this is the polar opposite of most sprinters/weight lifters who put a larger focus on eating massive amounts of protein which you need to maintain muscle mass.

So should you be running or sprinting for the best look physique?

Obviously, most of you guys are not marathon runners.

I know most of my readers simply want to look and feel good and that’s great. And if that’s the case, just stick with a couple heavy lifting sessions per week and maybe throw in a quick workout finisher at the end.

My main point that I want to drill into your head is – don’t believe that doing a little or even a lot of cardio will cause you to lose muscle. The act of running itself doesn’t cause muscle loss, but it does take your focus and energy away from things like weight lifting.

What are your thoughts? How do you incorporate running or sprinting into your workout routine?

Long distance cardio is terrible for your health, especially your heart. It’s a tremendous strain plus it weakens your immune system. I do only HIIT and interval-style cardio and weights. I’ve had three babies and I have a abs and wear a size two. Oh, and I eat. A lot.

Wow, this is the dumbest thing I’ve read in a while.

Great article! I’m so tired of people body shaming marathon runners. As a female, I would never want to look like I could bench press my own weight. I personally don’t find extreme body building physiques attractive. I don’t go around shaming them for the way they look. If you’re not into endurance sporting, don’t run long distances. If you aren’t into heavy weights don’t lift. What a marathon runner may lack in physical strength, they make up in endurance and the opposite goes for body builders. These are two completely different ways to exercise. Sheesh!

    Coming from the male point of view that I know of. I think running has the inferior physique 😛

    I would say it goes the other way too

I came here looking for information for my persuasive essay I am writing. Keith, you have a good start, I am a body builder personally but both my parents prefer the distance route and have run multiple marathons. Distance running does in fact burn muscle fiber though. Our bodies adapt to what it’s thrown into. I think one of the biggest reasons, which while reading this article I was waiting for, is supplying oxygen to a muscular frame is far more extensive than a thinner one. A muscular person can be good at running but they will never be as good as Dathan Ritzenhein for example, who is freakishly skinny in my opinion. If someone runs as much as a distance runner has to in preparation for a marathon, their bodies would immediately start eliminating it’s muscle which makes it easier to supply more oxygen to it.

This is also highly dependent on ones VO2 level, which is the rate that someone can consume oxygen. All humans have a peak and that’s roughly 85 ml/kg/min, where as a horse for instance has a maximum of 200ml/kg/min. This is why they can run so much longer then we can. Our muscle requires high amounts of oxygen while it’s being used and running by far requires the most when it’s for that long, the only way for the body to adapt to that much running at some point is to simply eliminate muscle so it doesn’t need to fuel as much of it.

Great concept to write on but I’d get a little more information though.

Well, I must say, my muscle mass has diminished quite a bit over the past year, since beginning long distance running (about 25-30 miles per week on average). That said, my waist is slim, bodyfat at all time lows, and I feel great. What is equally puzzling is, my strength is up some-despite the loss of mass. So, am I experiencing muscle loss due to the running, or some sort of restructuring of the fibers, etc? It is odd I would lose so much volume, but still benching and curling the same amount of weight.
