Though I wouldn’t call any of this philosophy per se, this book does contain a certain amount of what might be dubbed life lessons. They might not amount to much, but they are personal lessons I’ve learned through actually putting my own body in motion, and thereby discovering that suffering is optional.

Muscles really are like animals, and they want to take it as easy as possible; if pressure isn’t applied to them, they relax and cancel out the memory of all that work. Input this canceled memory once again, and you have to repeat the whole journey from the very beginning.

Competing against time isn’t important. What’s going to be much more meaningful to me now is how much I can enjoy myself, whether I can finish twenty-six miles with a feeling of contentment. I’ll enjoy and value things that can’t be expressed in numbers, and I’ll grope for a feeling of pride that comes from a slightly different place.

All I have to go on are experience and instinct. Experience has taught me this: You’ve done everything you needed to do, and there’s no sense in rehashing it. All you can do now is wait for the race. And what instinct has taught me is one thing only: Use your imagination. So I close my eyes and see it all. I imagine myself, along with thousands of other runners, going through Brooklyn, through Harlem, through the streets of New York.

From out of the failures and joys I always try to come away having grasped a concrete lesson. (It’s got to be concrete, no matter how small it is.) And I hope that, over time, as one race follows another, in the end I’ll reach a place I’m content with. Or maybe just catch a glimpse of it. (Yes, that’s a more appropriate way of putting it.)
