(BOSTON) -- Kenyan Geoffrey Mutai won the Boston Marathon Monday with the fastest time ever recorded for the 26.2-mile race: two hours, three minutes and two seconds. That's an impressive average speed of 4.69 minutes per mile.
The bad news: his mark won’t be counted as a world record by the International Association of Athletic Federations, the world governing body for track and field, because part of the course is downhill.
American Ryan Hall finished fourth in two hours, four minutes and 55 seconds. It's the all-time fastest marathon time by a U.S. runner under all conditions.
Kenya’s Caroline Kilel won the women’s race in two hours, 22 minutes and 36 seconds. Desiree Davila of the United States led for much of the latter half of the race and swapped leads with Kilel twice in the final minutes before finishing two seconds off the pace.
