Bolt clinches sprint double

Jamaica's Usain Bolt on Wednesday night became the first man to win the Olympic sprint double for 24 years with his second world record in five days in Beijing.

Bolt, who casually shaved 0.03 seconds off his own record in winning the 100 metres title in sensational style on Saturday, clocked 19.30secs to break Michael Johnson's 12-year-old record of 19.32s.

Churandy Martina of the Dutch Antilles and American Wallace Spearmon were initially credited with silver and bronze, only to both be disqualified for running outside their lanes. That gifted American Shawn Crawford the silver medal with team-mate Walter Dix claiming bronze.

Bolt admitted it was 'dream come true' to complete the sprint double, setting world records in both and said: "It's great. I have a great feeling. This is a dream come true really."

He added: "You come out here every day as an athlete to be a champion and this is just more than I can handle really, I'm just happy for myself.

Bolt didn't feel the world record was a possibility as the exertions of the heats and 100m were starting to take effect.

"To tell you the truth I was worried because after the semi-finals I was kind of feeling a bit tired and I was saying 'coach, it's going to be rough'.

"But I just told myself and I told everyone I was going to run hard here and leave everything on the track and I did just that.

"I feel great, I can't explain how I feel. I just proved to the world that I'm a true champion and that with hard work you can do anything possible."

Britain's Christian Malcolm finished fifth after the disqualifications in 20.40.
