Jemima Sumgong of Kenya survived a bad fall late in the race to win the women's London Marathon for the first time on Sunday.

Sumgong banged the side of her head off the road when three runners went down after clashing at a drinks station, but she rejoined the leaders and eventually outpaced last year's winner, Tigist Tufa of Ethiopia, over the last mile.

It was the Kenyan's first major marathon victory since Rotterdam three years ago and followed runner-up finishes in Boston, Chicago and New York.

She posted an unofficial time of two hours 22 minutes and 58 seconds, five seconds ahead of Tufa with third place going to Florene Kiplagat of Kenya in 2:23:29.

The men's event also saw Kenyan glory as Sumgong's compatriot Eliud Kipchoge took first place, setting a new course record in the process.
