Usain Bolt and Mo Farah set for Block-Buster showdown

The two fastest men in the world in their own rights are set to face off in a 600 metres race for charity.

Usain Bolt who is known as the king of sprint won two individual gold medals at the last olympics, Mo Farah also won two olympic gold medals in London last year and he's highly regarded as the 'Kabiyesi' of long distance race.

The race could raise money for their own foundations by going head to head at the rarely run distance.

Farah said yesterday: '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 challenged Bolt: 'Are you up for that? Come on, you’ve got to do it.'

Thirty-year-old Farah, Olympic champion at 5,000m and 10,000m, said the distance would have to be between 600m and 800m.

'Let’s get it on,' Farah said.

Bolt replied, 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.'

In an interview shown on Sky News, Bolt, world record holder at 100m and 200m, said running 1500m 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.'

This is not the first time sports fans will be treated to an anomaly, in 2007 King of clay Rafa Nadal went on a showdown with the King of Grass Roger Federer in 'The battle of surfaces'. The match was played on a unique court with a clay surface on one side of the net and grass on the other.

Also sometimes next month there is due to be a battle of the sexes where reigning Wimbledon champion Andy Murray will play no 1 ranked female tennis player Serena Williams (HERE).
