Kenya’s Ruth Chepngetich obliterated the field to win the women’s Chicago Marathon in 2:22:31 on Sunday, as Ethiopia’s Seifu Tura claimed victory in the men’s race.

Chepngetich, who won gold at the 2019 world championships, went out fast, securing a 27-second lead through the first 10 kilometres and never let up, finishing a minute and 49 seconds ahead of second-placed American Emma Bates.

It was the first major title for Tura, who held off 2017 champion Galen Rupp through the final stretch to finish 23 seconds ahead of the American in 2:06:12.

Tura’s compatriot Shifera Tamru got the men’s race off to an aggressive start, leading by a 15-second margin through the first 15 kilometres but he faded to finish fifth.
