Kenyan clean sweep at NY Marathon

New York - Stanley Biwott and Mary Keitany ran to a Kenyan sweep of the New York City Marathon titles on Sunday.

Biwott took command by the 23rd mile and pulled away from his biggest challenger fellow Kenyan Geoffery Kamworor to claim the men's crown.

Fourth in London earlier this year, Biwott won in an unofficial time of two hours, 10 minutes and 34 seconds.

Kamworor came home in 2:10:48 with Ethiopia's Lelisa Desisa third in 2:12:10.

Defending champion Wilson Kipsang of Kenya faded to fourth.

Keitany surged to the front for keeps shortly after 18 miles and triumphed in an unofficial clocking of 2:24:25.

The tiny Kenyan quickly broke London Marathon champion Tigist Tufa of Ethiopia in the 22nd mile and ran the remainder of the race alone.

She became the first back-to-back New York champion since Briton Paula Radcliffe won in 2007 and 2008.

Ethiopia's Aselefech Mergia took second in 2:25:32 with compatriot Tufa third.
