Boston Marathon officials say they will apply to the international track governing body to have Geoffrey Mutai's winning time of 2 hours, 3 minutes, 2 seconds certified as a world record.
IAAF rules say the Boston course is ineligible to set a record because it is technically downhill. The course's layout also allows for a tailwind that wouldn't be possible on a loop course like the governing body prefers.
But Boston officials say that the 115-year history of the race shows it is not an artificially fast course. The Boston Marathon is the world's oldest annual marathon — older than the IAAF itself.
Mutai and second-place finisher Moses Mosop, both Kenyans, both broke Haile Gebrselassie's sanctioned world record of 2:03:59.
