Mary Keitany won her second straight New York City Marathon on Sunday to become the first woman to repeat since Paula Radcliffe in 2008.

Kenya's Stanley Biwott was the men's winner.

Keitany, a 33-year-old Kenyan, defended her title in an unofficial time of 2 hours, 24 minutes, 25 seconds, beating Ethiopia's Aselefech Mergia by 67 seconds.

Keitany pulled away around the 21-mile mark to become the eighth woman to win more than once in New York.

The two-time London Marathon champ had twice finished third in New York before breaking through last year when she won by just 3 seconds. That was her first marathon since 2012 because of the birth of her second child.

Ethiopia's Tigist Tufa took third.

Biwott won his first major marathon title after finishing second in London last year. He finished in 2 hours, 10 minutes, 34 seconds, beating countryman Geoffrey Kamworor by 14 seconds. Reigning Boston Marathon champ Lelisa Desisa was third.
