Jamaica's triple Olympic champion Usain Bolt revealed on Wednesday he would compete in the Bislett Games in Oslo on June 7 as he cranks up his preparations for defending his titles in the London Olympics in August. The 25-year-old, world record holder in the 100 and 200m, said that he hoped his run in Oslo would be an important step on his way to London. "My preparations have been good this fall," said Bolt, who surrendered his world 100m title last year when he was disqualified for a false start in the final. "I am injury free, working hard and everything is going according to plan. I hope to come to Bislett prepared and ready to run a great race. "This year is really important for me as it is an Olympic year and I am aiming to defend my three gold medals from Beijing. My 100 metres race at Bislett stadium June 7th will be an important stepping stone towards that goal." The meet organisers were ecstatic to have got him to run there. "We are proud of having the biggest sport stars in the world lined up for our 100 metres race," said meeting director Steinar Hoen. "There is only around six weeks to go to the London Olympics after this race and there is no doubt it will be surrounded by an enormous amount of interest." In addition to his three gold medals from the 2008 Olympic Games - the 4x100m relay being the other, Bolt has won five world titles - two in the 200m and 4x100m relay and one at 100m - and also holds the World record in the 100m, 200m, and 4x100m relay along with his Jamaican teammates.
