Olympic champion Peres Jepchirchir (30) won the women's London marathon in a world record time of 2 hours 16 minutes 16 seconds for a women's only race on Sunday.
The Kenyan came home in front of Tigst Assefa and Joyciline Jepkosgei to break the world record mark without male pacemakers.
Jepchirchir beat the women's-only course record of 2:17:01 set by Kenya's Mary Keitany in 2017.
Retired British star Paula Radcliffe ran a time of 2:15:25 in a mixed-sex marathon in London in 2003, using male pacemakers.
World record holder Assefa had been the pre-race favourite but she could not live with Jepchirchir's kick for the finish line inside the final kilometre.
Both she and Jepkosgei also finished inside the previous women's-only record time.
Two-time former London marathon winner Brigid Kosgei finished fifth behind Megertu Alemu.
