Bolt said today he wants to win more gold in Rio, set another world record in the 200 meters next year, and perhaps win a gold medal at the Commonwealth Games.
"So far, (it) is after the Olympics in Rio," Bolt said of his retirement plans. "I think if I am in great shape, I'll go there and do what I have to do. I think it will be a good time to retire, on top."
Winning another three golds in Moscow last month made him the most decorated athlete in world championship history with eight gold and two silvers. He has six gold medals from the Olympics.
Bolt won the 100, 200 and 4x100 relay at the 2008 Beijing Olympics and at last year's London Games. He won the same triple at the 2009 worlds before repeating that feat in Moscow last month.
At 27, Bolt has the experience to know that a lax season midway between Olympics can hurt him. In 2010, a soft entry into the year and subsequent injury cost him almost a full season.
