Usain Bolt says his goal for 2014 is to break his own 200-metre world record of 19.19 seconds.
Speaking at a sponsor event on Friday, Bolt says "hopefully everything will go well with training and I can go out there and break a world record … it's all about not getting injured this season."
Bolt won the 100-, 200- and 4x100-metre relay at the 2008 Beijing Olympics and again at last year's London Games. He won the same three golds at the 2009 worlds before repeating that feat in Moscow in August.
Bolt, who has said he plans to retire in 2017, said he would like to go to the Tokyo Olympics in 2020 but only as a spectator.
