While both athlete’s main focus is on the World Athletics Championships in Moscow from August 10-18, Farah’s invite to the Jamaican fastest ever man may have legs.

They are friends and have the same agent – Bolt donated his 100m winning shoes to Farah’s foundation.

“He’s got his charity foundation, I’ve got the Mo Farah Foundation,” Farah said. “It would be great to do a distance where people, proper athletics fans, vote in on what distance they think is most suitable.”

Farah said a distance between 600m and 800m would be about right.

“Are you up for that?” he asked Bolt. “Come on, you’ve got to do it. Let’s get it on.”

Bolt said. “It sounds like fun,” he said. “It would be tough, but for charity. 600 would be better for me.”

Farah was speaking at the London Anniversary Games, at which he won the 3000m.

Bolt won his 100m and relay with the Jamaican team at the Grand Prix event which also celebrate a year since the London Olympics.

Bolt has previously turned down a challenge from Kenyan 800m world record holder David Rudisha to a 400m race.
