I'm going to work so that it's a pure guts race at the end, and if it is, I am the only one who can win it.

Having a true faith is the most difficult thing in the world. Many will try to take it from you.

The best pace is a suicide pace, and today looks like a good day to die.

You have to wonder at times what you're doing out there. Over the years, I've given myself a thousand reasons to keep running, but it always comes back to where it started. It comes down to self-satisfaction and a sense of achievement.

Every once in a while I think, 'What am I doing out here running, busting myself up? Life could be so much easier. The other guys are out having fun, doing other things, why not me?'

What I like most about track is the feeling I get after a good run.

No one will ever win a 5,000-meter by running an easy two miles. Not against me.
