Bolt hopes to become London 2012 legend

Usain Bolt says he wants to try to become a "legend" by winning four gold medals at the 2012 London Olympics.

The triple Olympic gold medallist from 2008 wants to run for the Jamaican 4x400m team, as well as competing in the 100m, 200m and 4x100m relay.

"If I'm fit, I definitely want to go for the 4x400m," he told BBC Sport.

"That would put something extra on trying to be a legend by winning four gold medals, it would make my victory just a little more greater."

In an exclusive interview, the world's fastest man explained it was his team-mate and good friend, Jermaine Gonzales, who persuaded him to try and emulate fellow sprinters Carl Lewis and Jesse Owens by winning four medals at a single Olympics.

"Jermaine Gonzales asked me last year if I would run in the four by four and I said 'no, I'm not fit enough. If I go on your team, I'll probably be the weak link'," said Bolt.

"But, if I'm fit enough, I'm ready and I will definitely try."

But Bolt has also confirmed he intends to extend his career by a year to compete at the World Athletics Championships in 2017 after London won the bid to host the event.

The 25-year-old, who will be 31 in 2017, had previously said he would retire following the 2016 Olympics in Brazil.

"If this Olympics goes as well as I want it to go then I will definitely stay on. It will be a good look to run at a last World Championships and then retire in London. We'll see," said Bolt.

Asked what events he would aim to compete in, he said: "I'll just pick one - probably the 200m. It depends on how my career goes. But I can't worry about that right now."
