Kenya's Keitany wins London Marathon in record time

London (AFP) - Kenya's Mary Keitany set the fastest time in a women-only marathon as she won a third London Marathon on Sunday in an unofficial 2hrs 17min 01sec.

The 35-year-old, who also has three New York Marathon victories, beat Ethiopian track great Tirunesh Dibaba by almost a minute.

Keitany went out at breakneck speed, helped by a pacemaker, and was on record pace when left on her own with about 10 miles to go.

Dibaba was the only one who looked capable of throwing down some sort of challenge.

Keitany started to pay for her early efforts but Dibaba -- known as the "Baby Faced Destroyer" -- made little inroads into the Kenyan's lead, trailing her by over a minute at the 18-mile mark.

However, the Ethiopian did make some ground up as the Kenyan slowed, but just as she had Keitany in her sights, Dibaba started to feel her stomach and came to a halt briefly.

Dibaba managed to get going again but her chance of victory was gone and Keitany came home alone to great roars from the massed crowd on The Mall.
