"People can't understand why a man runs. They don't see any sport in it. Argue it lacks the sight and thrill of body contact. Yet, the conflict is there, more raw and challenging than any man versus man competition. For 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 master himself and his emotions."
American runner, Olympic Games medalist
