The inspiration for the marathon was a man named Philippides. According to Greek myth, Philippides ran from the battlefield at Marathon all the way to Athens to announce Greece’s victory over Persia. He ran roughly 26 miles as fast as his legs could carry him – an amazing athletic achievement.
No one seems to remember though what happened next to Philippides: he collapsed and died on the spot.
Training for a marathon is an increasingly popular activity these days. For a lot of folks the marathon represents the absolute pinnacle of fitness. “If I can run a marathon,” the thinking goes, “then I’ll really be in shape.” Chances are you’ll wind up in some shape, it just might not be good shape.
I think that the volume that training for a marathon requires is far too much for the majority of us and leads to unnecessary wear and tear on the joints. There’s a certain point at which the exercise that we do ceases to be beneficial and actually becomes harmful. Sometimes it’s difficult to recognize this point because exercise is promoted as being good for us; so logically more of it must be better. Not so. Exercising too much can raise levels of stress hormones causing our bodies to break down muscle and store fat. Just take a look at a marathoner. Most don’t look at all like pictures of health; they look like they’re wasting away to me.
Don’t get me wrong: I think that running can be great for fitness. But there’s a sweet spot where we can get most of the benefit while avoiding much of the harm. (It varies from individual to individual.) Perhaps running briskly for 20 minutes doesn’t gives us the same bragging rights that running a marathon does, but it might do us better at the end of the day.
