Rio 2016 will be my last Olympics, confirms Usain Bolt

Usain Bolt has confirmed that Rio Olympics will be his last, snuffing out the possibility of extending his career to the 2020 games in Tokyo.

The 29-year-old Jamaican sprint champion, who has won six gold medals in 100-metre, 200-metre and relays in the past two Olympics, says he doesn't have the desire to compete at Tokyo in 2020.

However Bolt said subsidiary 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."

"My biggest dream at the Olympics is to win three gold medals again," he said.

"That's my focus, that's what I want. And that's what I'm aiming for because that's my goal and that's my dream."
