It's impossible not to watch Usain Bolt when he's on the track.
The Jamaican sprinter is seeking an unprecedented third straight gold at the 100 meters Sunday night at the Rio Olympics.
Bolt won his first heat in 10.07 seconds Saturday and is still a favorite, despite a sore hamstring that forced him from the world championships last month.
American Justin Gatlin posted the fastest time in the Rio heats. Others in the mix include Andrew Fisher, a Jamaican who competes for Bahrain, Jamaican Yohan Blake, Americans Marvin Bracy and Trayvon Bromell and Frenchman Christophe Lemaitre.
