Kenya’s Brigid Kosgei won the women’s title in 2:18:35, also a personal best. Ethiopia’s Roza Dereje was second in 2:21:18 with compatriot Shure Demise third in 2:22:15.
Two-time champion Florence Kiplagat of Kenya, returning to competition after dropping out of last year’s race with a thigh injury, was fourth, 7:33 adrift.
For Kosgei, it was a breakthrough win after runner-up showings last year in Chicago and this year in London.
She was among seven African runners that pulled ahead by more than 70 seconds after the first 5km and doubled that margin by the 10km mark.
Kosegi, 24, surged ahead by 45 seconds at 35km and stretched her lead to the finish line.
“I feel OK because last year I was position two,” she said after the race. “Today I have a bit of an injury but I broke my time. I was injured but the problem, the injury, I swallowed the pain.”
Kosgei wowed fans last year with a second place finish in Chicago, running the sixth fastest time ever run in the Windy City race.
She said she enjoyed the rain that fell on runners during this year’s race.
“I enjoy when the rain is coming. I enjoy the run more than no rain,” she said.
She opened her 2018 season with a boom, finishing second in London. With Sunday’s race, Kosgei has finished first or second in eight of her nine career marathons.
