Usain Bolt said he is “50-50” on competing at the 2017 World Championships in London, which he previously stated would be his final competition before retiring.
He may retire after his fourth Olympics in Rio next year instead.
“I really want to run at London, but I think the sport is not as fun as it used to be,” Bolt said on BBC radio after winning the 200m at the World Championships in Beijing on Thursday night. “It’s more taxing. I can’t enjoy it as much as I want to because I have to be sacrificing a lot more, so, uh, it’s 50-50, I’m telling you.
