Runner LaShawn Merritt poses for a portrait at the U.S. Olympic Committee Media Summit in Beverly Hills, Los Angeles, California March 8, 2016. "I don't really listen to music when I train," said Merritt. "When I grew up I was in a band, so I listened to jazz a lot to calm me down. I played the trumpet and the baritone for 8 years."
