Mary Keitany wins women's London Marathon

Mary Keitany has claimed victory in the women's London Marathon for the second successive year.

The Kenyan equalled her personal best to record the fourth-fastest time in the event's history and book her place at London 2012.

Keitany's unofficial time was an African record of 2:18.36 to edge out second-placed Edna Kiplagat, who finished just inside the 2:20 mark.

Priscah Jeptoo came in third to round off a all-Kenyan top three.

Claire Hallissey was the first British athlete to cross the finish line, recording a score of 2:28, which may be enough to claim her a place at the Olympic Games.
