Fastest marathon ever run in Boston

5:52 am on 19 April 2011

Kenya's Geoffrey Mutai has run the fastest marathon in history to win the 115th Boston Marathon while compatriot Caroline Kilel took the women's crown.

Mutai took two hours, three minutes and two seconds to complete the mainly downhill course and also broke the Boston record set last year by another Kenyan Robert Kiprono Cheruiyot: 2:05:52.

He defeated countryman Moses Mosop by four seconds.

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.

New Zealand's Kimberley Smith had to pull out at the Mile 20 mark.

Smith, who's based in Rhode Island, had been leading the women's elite pack when she appeared to stumble 90 minutes in, struggled to run on and was quickly overtaken by the pack of Kenyan and Ethiopian women behind her.
