LONDON - TRIPLE Olympic champion Usain Bolt will run the 4x100 relay at the London Grand Prix later this month.

Bolt had already announced his participation in the 100 race at the event, as he prepares for the world athletics championships in Berlin next month.

The London Grand Prix is held July 24-25.

Bolt said Monday that 'racing at Crystal Palace in two different events over the two days will be the ideal tuneup for me ahead of Berlin.'

Bolt established himself as the world's fastest man with astonishing performances in Beijing, setting world records in the 100, 200 and relay event. -- AP
