Lelisa Desisa of Ethiopia is the men's elite winner of the 2013 Boston Marathon, finishing with a time of 2:10:23. This was only Desisa's second marathon; he previously won Dubai in January. Finishing behind Desisa was Micah Kogo of Kenya, and in third, Gebregziabher Gebremariam of Ethiopia.
While Americans Jason Hartmann and Fernando Cabada broke out to lead the pack in the early stages of the race, the latter part of the race was dominated by a pack of Kenyan and Ethiopian runners. The last mile of the course was a neck-and-neck race until Desisa sprinted ahead during the last few blocks. Despite their best efforts, neither Kogo nor Gebremariam were able to close the gap.
