Brussels: Usain Bolt will run the 100 meters in the fastest field ever assembled at the Van Damme Memorial on Friday, seeking to break the world record for the third time this season.

The Olympic champion will face Asafa Powell, the former record-holder who matched the second fastest 100 of all time on Tuesday, and Tyson Gay, the world champion seeking to recapture his form after a hamstring injury.

They are the three fastest men ever and have posted the 10 fastest 100 dashes ever run. Meet organizer Wilfried Meert said such a select field is unique.

"This has never happened before," Meert said.

All eyes at the 50,000-capacity King Baudouin stadium will be on Bolt.

The Jamaican won three gold medals and set three world records in Beijing last month to become the face of the games alongside swimming great Michael Phelps.
