World 200m Sprint Champion Allyson Felix Discusses Her Biggest Rival Ahead of U.S. Championship Trials

World 200m sprint Champion Allyson Felix says she doesn't think about her archrival Veronica Campbell-Brown anymore. The 23 year old who has started the training build up to defend her World 200m title in Berlin this August believes a race against Campbell-Brown only makes her run faster.

The 23-year won three gold medals in Osaka, Japan in 2007, the 200m title and two relay gold's for the American team. She's only the second women in history to achieve such honours at the World Championships.
