Bolt, Powell to clash again in London

The fastest man in the world Usain Bolt and his Jamaican teammate former world record holder Asafa Powell will race against each other in the 100 metre at the London Grand Prix on July 24.



This will be the final race between the two before the World Championships in Berlin, which start on August 15.



The 26-year-old Powell is unbeaten over the distance at Crystal Palace, winning on his three previous visits.



Bolt won both the 100 and 200 at the Beijing Olympics and set a world record in both events. He and Powell were part of Jamaica\'s 4 x 100 relay team, which also won gold in record time.



Bolt, who was last beaten on the track by Powell in Stockholm last July, will also run the 4 x 100 metres.



American Tyson will also run in London, but in the 200 metre.
