Kenya's Geoffrey Mutai won the Boston Marathon on Monday in an unofficial time of two hours three minutes and two seconds, the fastest time ever recorded over the distance.
Mutai slashed almost a minute off the existing world record of 2:03.59, set by Ethiopia's Haile Gebrselassie at Berlin in 2008, but his time was not ratified as a new record because he was aided by a tailwind on a downhill course.
"Boston marathon performances cannot be ratified as world records as the course does not satisfy two of the criteria for world records," USA Track and Field told Reuters.
Mutai's countryman Moses Mosop also smashed Gebrselassie's mark to finish second in 2:03.06 after the pair ran stride for stride before a final sprint down Boston's Boylston Street.
Ryan Hall of the United States finished third. His time of 2:04:58 was the fastest ever time by an American in the 115th running of the race.
Caroline Kilel ensured a Kenyan double when she won the women's race in a 2:22.36, outkicking U.S. runner Desiree Davila in the final few blocks. Kenyan Sharon Cherop was third.
Mutai and Kilel eached earned $150,000 for their wins while the 29-year-old Mutai, whose previous biggest win was the 2008 Monaco Marathon, would pocket a bonus for breaking the course record, which happened on the same day Gebrselassie celebrated his 38th birthday.
