I run because I enjoy it — not always, but most of the time. I run because I have always run — not trained, but run. What do I get? Joy and pain. Good health and injuries. Exhilaration and despair. A feeling of accomplishment and a feeling of waste. The sunrise and the sunset.

In running, it doesn't matter how fast or slow you are relative to anyone else. You set your own pace and you measure your own progress. You can't lose this race because you're not running against anyone else. You're only running against yourself, and as long as you are running, you are winning.

I always tell beginning runners: Train your brain first. It's much more important than your heart or legs.

Courage is crossing a starting line.

The most powerful lesson you can learn in running? You're capable of much more than you think.

Why run? I run because I am an animal. I run because it is part of my genetic wiring. I run because millions of years of evolution have left me programmed to run. And finally, I run because there’s no better way to see the sun rise and set... What the years have shown me is that running clarifies the thinking process as well as purifies the body. I think best - most broadly and most fully - when I am running.

Success does not come to the most righteous and rigorously disciplined but to those who continue running.
