Boston - Kenya's Geoffrey Mutai set an official world record for the men's marathon at the Boston Marathon on Monday, slashing almost a minute off the previous mark.
Mutai completed the course in an unofficial time of two hours three minutes and one second, shattering the existing record of 2:03.59 set by Ethiopia's Haile Gebrselassie at Berlin in 2008.
Mutai held off countrymen Geoffrey Mosop in a sprint down Boston's Boylstron Street after favorably cool temperatures and a significant tailwind combined to set the stage for fast times.
Kenyan Caroline Kilel won the women's race in an unofficial time of 2:22.36.
