This weekend, 50,000 runners will toe the line at the New York City Marathon (the world's largest 26.2!)-and we're guessing that, throughout their training, many of them could relate to the narrator in the quick flick below: “I'm 15 miles into this run,” he says, groaning. “I have another seven to go. I'm losing steam, my legs are cramping, I can barely breathe. I don't know if I can make it another mile!”
While we hope the marathoners feel better than that on Sunday morning, we'll admit it: We've been there.
The video, from the American Chemical Society, goes on to explain the science behind why we “bonk,” “hit the wall,” or, if we're lucky, catch the drug-like runner's high. (Hint: It's got a lot to do with proper training.)
Whether you're racing this weekend or not, give it a watch. Then get out there and go chase that dopamine rush-through NYC's five boroughs or wherever you love to pound the pavement. Good luck, marathoners!
