Assefa dominates to claim victory at London marathon

Ethiopia's Tigst Assefa shattered the women's-only world record in winning the 45th London Marathon on Sunday, while Kenyan Sebastian Sawe made a brilliant tactical decision to demolish a stacked men's field en route to victory.

The 28-year-old Assefa, silver medallist in the event at last year's Paris Olympics, pulled away from Joyciline Jepkosgei of Kenya over the final couple of kilometres after the two had set a blistering early pace.

She crossed the finish line in two hours, 15 minutes and 50 seconds, beating the previous women's-only record of 2:16:16 set last year in London by Kenyan Peres Jepchirchir, and said the blazing London sun helped, with temperatures approaching 20 degrees Celsius by race's end.
