"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" .
Glenn Cunningham,
  two-time U.S. Olympian
