Usain Bolt is celebrating 200m win at Beijing athletics world championships on Aug. 27, 2015.
Usain Bolt has confirmed he will retire after this year's Olympic Games in Rio de Janeiro despite calls to prolong his career.
The six-time Olympic gold medalist suggested in January that he could continue competing until the 2020 Games in Tokyo on the advice of his coach Glen Mills.
But the Jamaican said success in Rio would leave him with little reason to continue at the elite level.
"It'll definitely be my last Olympics," the 29-year-old told AFP on Monday. "It's going to be hard to go four more years for me, to keep the motivation that I want, especially if I accomplish what I want to in Rio.
"It's going to be hard to keep the motivation to go on for four more years so it'll definitely be my last one."
