The Jamaican triple Olympic champion says he has been working to become faster out of the blocks, and that when he gets the start just right ''it should be a world record.''

Bolt is unlikely to threaten his mark of 9.58 seconds when he runs the 100 meters at Friday's Golden Spike meet. But he says he has still time to find his optimal form before London.

Bolt says: ''All I have to do is to work on transition and technique. We have probably two months to get it right, so it shouldn't be a problem. I'm definitely on the right track.''
