Usain Bolt accepts challenge from Mo Farah to race for charity
Farah, who won gold at the 5,000 and 10,000 metres at the London Olympics last year was the star turn of the Games along with Jamaican sprinter Bolt, who won the 100 and 200 metres.

Olympic sprint champion Usain Bolt accepted a challenge from Britain's Olympic middle- distance champion Mo Farah to race for charity, saying he would be prepared to meet over 600 metres.
Farah, who won gold at the 5,000 and 10,000 metres at the London Olympics last year was the star turn of the Games along with Jamaican sprinter Bolt, who won the 100 and 200 metres.
"It would be great to do a distance where people - proper athletics fans - vote on what distance they think is most suitable," Farah told Sky Sports.
He then turned to the camera and said: "Are you up for that? Come on, you've got to do it."
In a separate interview, Bolt was shown the footage and said he would be prepared to take on the challenge. "That sounds fun," Bolt said. "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."
