The Jamaican sprint king had raised the prospect of prolonging his Olympic career in January after revealing that his coach Glen Mills had suggested his fitness would carry him through to Japan.
However, Bolt told AFP subsidiary SID in an interview that the curtain would come down on his Olympic career in this year’s games in Rio de Janeiro, where he is targeting three more gold medals.
“It’ll definitely be my last Olympics,” Bolt said. “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.”
