Daniel Wanjiru claimed a surprise London Marathon win ahead of a resurgent Kenenisa Bekele, while Kenyan compatriot Mary Keitany lit up the women's race on Sunday.
Wanjiru, 24, secured the biggest triumph of his career with a bold run that left Ethiopia's Bekele, last year's Berlin Marathon winner, with too much to do.
Despite a strong finish, Bekele could not close the gap as Wanjiru held off the 5000 and 10,000 meter world record holder, with Bedan Karoki third.
Keitany knocked 41 seconds off the women-only world record, the 35-year-old crossing the line in 2:17.01 — the second fastest time in history by a woman.
It marked her third marathon success in London as she finished ahead of Tirunesh Dibaba and Aselefech Mergia.
Keitany's time is the quickest in an exclusively female race, while Paula Radcliffe's long-standing world record of 2:15.25 came when she ran against men and women.
