Bolt eyes four years of rule
Usain Bolt aims to preserve his sprint dominance and add to his collection of six Olympic gold medals before he ends his glittering career after the Rio de Janeiro Games in 2016.
"I have pretty much four more years in the sport, so now it is all about dominating for those four years," Bolt stated.
"I am looking forward to the next Olympics to do something that has never been done before, so that is one of my biggest things right now."
The Jamaican – who has been nursing a hamstring strain this year – makes his European season debut at tomorrow's Golden Gala meeting that will also feature American Justin Gatlin and 2003 world champion Kim Collins.
