"People say it was degrading for an Olympic champion to run against a horse, but what was I supposed to do? I had four gold medals, but you can't eat four gold medals."

"I always loved to run. It was an escape from everything else."

"I let my feet spend as little time on the ground as possible. From the air, fast down, and from the ground, fast up."

"The world needs more heroes, but it also needs more people who are willing to fight for what's right."

"The only way to achieve greatness is to work hard."
