Instead of forcing myself to run, perhaps it would have been smarter if I’d walked. A lot of other runners were doing just that. Giving their legs a rest as they walked. But I didn’t walk a single step. I stopped a lot to stretch, but I never walked. I didn’t come here to walk. I came to run. That’s the reason—the only reason—I flew all the way to the northern tip of Japan. No matter how slow I might run, I wasn’t about to walk. That was the rule. Break one of my rules once, and I’m bound to break many more. And if I’d done that, it would have been next to impossible to finish this race.
