London Marathon 2013: Men's contenders
BBC Sport provides the lowdown on the men to look out for in Sunday's London Marathon.
Last year's winner Wilson Kipsang and fellow Kenyans Patrick Makaou and Geoffrey Mutai are expected to be pushed all the way by Ethiopian duo Tsegaye Kebede and Ayele Abshero.
Great Britain's Mo Farah says he will only run half of the 26.2 miles, while Ugandan Stephen Kiprotich has already demonstrated his ability to go the full distance on London's roads after winning Olympic gold in 2012.
Coverage of the London Marathon will be available on BBC One, the Red Button, the BBC Sport website, on mobile, on the BBC Sport app and Connected TV.
