Before me, sprinters retired at 23 or 24. I run because I still like it, I can make a living, and I feel I was born to do it. And because people tell me I can't do it.Evelyn Ashford
Humans are built for endurance, not speed. We're awful sprinters compared to every other animal. We try to run our races as if they were speed races, but they are not. They're endurance races. Even a marathon, the way it's run now, it's not an endurance contest. Christopher McDougall
