(Reuters) - Kenya's Brigid Kosgei improved on last year's second place to win her first London Marathon title on Sunday, finishing ahead of reigning champion Vivian Cheruiyot, with fellow Kenyan and three-times winner Mary Keitany down in fifth.
Chicago Marathon champion Kosgei opened up a commanding lead over pre-race favourites Keitany and Cheruiyot and impressively pulled away from the star-studded field to win in a personal best time of two hours, 18 minutes and 20 seconds -- -- over a second ahead of Cheruiyot in second and Ethiopia's Roza Dereje in third.
