Usain Bolt plans to retire in 2017

Usain Bolt plans to retire after the 2017 world championships in London, the record-setting Olympic sprinter told British newspaper The Daily Mail.

Bolt previously had indicated that he would end his storied career after the 2016 Olympics in Rio de Janeiro.

But the six-time Olympic gold medal winner acknowledged to The Daily Mail that his sponsorship commitments have forced him to continue sprinting until 2017.

"That was the initial plan [to retire after the Rio Games]," Bolt told The Daily Mail. "But my sponsor has asked me to go on for another year, to 2017 and London.

"I'll be doing one event, the 100. I've already discussed it with my coach. I can concentrate on that, and on retiring on a winning note."

Bolt, 28, is the world-record holder in the 100, 200 and 4x100 relay.
