At the end of the New York City Marathon, Mary Keitany was back where she was a year ago — in first place at the finish line.

Keitany, the 33-year-old mother of two and the defending champion from Kenya, won easily in an unofficial time of 2 hours and 24 seconds, becoming the first woman to repeat as winner since Paula Radcliffe in 2008. Her 67-second margin over Ethiopia’s Aselefech Mergia was the largest since Radcliffe’s in ’08. Ethiopia’s Tigist Tufa took third.

Stanley Biwott, a 29-year-old who is also from Kenya, was the men’s professional winner. For Biwott, who finished in 2:10:34, the victory is his first major marathon title. He edged Geoffrey Kamworor of Kenya by 14 seconds, with Lelisa Desisa, the Boston Marathon winner, third and Wilson Kipsang, the defending NYC champ, fourth.
