As he nears the biggest race of his life, against Usain Bolt at the world championships on Sunday, the American hopes the world recognizes he is more than that - much more.

The 100m showdown in Beijing matches the 33-year-old, undefeated for two years in sprints, against Jamaican world record holder Bolt in the blue riband event.
