Usain Bolt has intimated that he would be willing to run a race against Mo Farah for charity.
Farah recently challenged the six-time Olympic gold medallist to a race at a compromised distance, and Bolt admits that the idea appeals to him.
"That sounds fun. It's going to be hard but it's charity so it's all about fun and enjoyment," Bolt told Sky Sports News.
"[1500m is] way too far. 600m, for sure I can try because I've done 600m in training."
Farah is a double Olympic champion, having won both the 5,000 and 10,000m at last summer's Games.
