Bolt wants four more years of dominance

Jamaica's Usain Bolt aims to preserve his sprint dominance and add to his collection of six Olympic gold medals before he ends his glittering athletics career after the Rio de Janeiro Games in 2016. "I have pretty much four more years I think personally, in the sport, so now it is all about dominating for those four years," Bolt, 26, said in Rome where he was preparing for Thursday's Golden Gala meeting.
