Kenya's Mary Keitany set a new world record to win the women's London Marathon.
Keitany broke Paula Radcliffe's 12-year women's only marathon record after posting two hours, 17 minutes and one second.
"I want to say it was a great day for me. It was really amazing," she told the BBC after her third win in London.
Keitany crossed the line well clear having broken away from the pack after just five kilometres.
She also set a new course record as she beat Radcliffe's previous women's only record of two hours 17 minutes and 42 seconds, set at the London Marathon in 2005.
Radcliffe still holds the women's world record of 2:15.25, set at the London Marathon in 2003 when she ran against men and women.
Keitany beat Ethiopia's Tirunesh Dibaba, who finished second, after Dibaba began to struggle on the Embankment, even stopping at one point as she appeared to clutch her stomach. Ethiopia's Aselefech Mergia finished third.
Alyson Dixon was the first British runner across the line, finishing 14th, to seal her spot in GB's squad for the summer's World Championships as five-time Olympian Jo Pavey dropped out after 16 miles.
Dixon ran a personal best of 2:29:06 while Charlotte Purdue and Tracey Barlow are now also expected to qualify for the World Championships after finishing 15th and 16th respectively.
In the women's wheelchair race Switzerland's Manuela Schar took the title for the first time.
