Bolt may retire 'on top' after 2012

Usain Bolt may retire from sprinting after the 2012 London Games, the triple Olympic champion disclosed yesterday.

"Definitely I will go one more Olympics for sure and from there I will decide what I want to do," the Jamaican 100 and 200 metres world champion said. "My coach may want to go to another one but we will determine how I am going because I definitely want to retire on top, like Michael Johnson," added Bolt, referring to the retired American who holds the 400 metres world record.

"I asked him why he retired and he said he'd done everything he wanted to so there was no reason for him to continue. He was on top, so I'm thinking if I'm on top and I've done everything I want to do maybe I'll get out."

Bolt stormed to world record times in the 100 and 200 at the Beijing Olympics and then smashed the marks at the World Championships last year.
