This is the quote on slideshow, it's one of my favorite and most appropriate running quotes that captures the heart of running and competiting. 

"People can’t understand why a man runs. They don’t see any sport in it, argue that it lacks the sight and thrill of body contact.

Yet, the conflict is there, more raw and challenging than any man vs. man competition.

In running, it is man against himself, the cruelest of opponents. The other runners are not the real enemies. His adversary lies within him, in his ability, with brain and heart to control and master himself and his emotions."
