LONDON, (Reuters) – Triple Olympic sprint champion  and world record holder Usain Bolt will fine-tune his world  championship preparations by running the 100 metres at the  London Grand Prix in July, organisers said yesterday.

Bolt took gold in the 100m, 200m and 4x100m relay in Beijing  last year, all in world record time, and the 22-year-old  Jamaican has confirmed that he will go over the shorter distance  at the two-day London Grand Prix at Crystal Palace on July  24/25, three weeks before the world championships in Berlin.

“London is a great meet and the fans there really get behind  everyone,” Bolt said in a statement.

“I normally base myself there during the summer so it is  like a second home. As usual there will be strong competition  but I guess that’s what I’ll need ahead of the world  championships.”

Last year Bolt warmed up for his Olympic feats by running a  19.76 second 200 metres at Crystal Palace, the fastest 200m ever  run in Britain.

“To win there in such style gave me a lot of pleasure. That  helped to build my confidence towards achieving the three gold  medals in Beijing a few weeks later,” he said.

Bolt will also run in England on May 17 when he goes over  150 metres in a street race in Manchester.
