Live coverage from BBC Sport Interactive of the 2013 London Marathon men's race.
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.
