Jamaican sprinter Usain Bolt has revealed that he is keen to compete in the 4x400m relay at the Olympic Games in London next year.

The 25-year-old, who won Olympic gold in the 100m, 200m and 4x100m relay in Beijing, has also confirmed that he has made his intentions known to the Jamaican team coach.

"If I can help to get them a gold medal, I will want to go on that team," Bolt said. "I've expressed that to my coach. If I am fit and I think I can do it.

"I definitely would want to try because if I do as well as in Berlin, the 4x4 would top it off and even make it a little bit much better.

"I will probably be in good shape and I know the guys are really stepping up the 400 level in Jamaica."

Should Bolt be granted his wish, he will only have to compete in the final of the two relay events.
