2017 C'ships Bolt's last

Jamaican sprint icon Usain Bolt has reaffirmed his decision to make next summer's Olympics in Rio de Janeiro his last, also revealing that he plans to retire from the sport after the 2017 World Athletics Championship in London.

The 29-year-old announced he will begin preparations for Rio from next Monday after enjoying a break away from athletics.

"I start training for the Olympics on October 12. It will be my last Olympics," Bolt said on Wednesday.

"I should have one more World Championships but I'm not too sure what I want to do after retiring. Some people say I should try acting but I think I will stay in sport and figure out what I can do," the six-time Olympic champion added.

He also revealed he was instructed to take up running by his former coach Pablo McNeil, at a time when he used to play cricket.
