One is the world’s fastest man, the other is one of Britain’s most successful athletes, and they could be going head-to-head in a race for charity.
Speaking to Sky, UK athletics star Mo Farah challenged Jamaican Usain Bolt to run over a distance of between 600 metres and 800 metres.
Farah, 30, is more used to competing over 5,000m and 10,000m, while Bolt specialises in the 100m and 200m.
They won their respective events at last year’s Olympics and struck up a special connection during the London Games.
So the charity race, if it happens, would be over an intermediate distance, raising money for their own foundations.
Farah, who is also in form in middle distance running as he recently broke the British 1,500m record, said: “He’s got his charity foundation, I’ve got the Mo Farah Foundation.
“It would be great to do a distance where people vote in – proper athletics fans – on what distance they think is most suitable.”
He then told Bolt: “Are you up for that? Come on, you’ve got to do it.”
Bolt, 26, replied he would be prepared to take on the challenge, saying: “That sounds fun.
“It’s going to be hard but it’s charity so it’s all about fun and enjoyment.
“I’m up for anything, for anything’s possible.”
Bolt, also the world record holder at 100m and 200m, said running 1,500m would be out of the question.
“It’s way too far,” he said. “Six hundred (metres) for sure I can try because I’ve done 600m in training.”
