Mo Farah 'excited' about running 2013 London Marathon

Double Olympic gold medallist Mo Farah says he is excited about taking part in the 2013 London Marathon, and sees it as an opportunity to "test" himself.

Farah won gold in the 5,000m and 10,000m at the London 2012 Olympics, and plans to run only half of the 26.2-mile course in this year's marathon on 21 April as "practice" for running the full distance in 2014.

Farah sees the event as a chance to thank the public for their support at the Olympics, especially as spectators do not have to pay for tickets to watch the marathon.
