The elite women's race starts at 0900 BST under blue skies and unseasonally high temperatures that will pass 20C

A leading group featuring Gete Wami, Zhou Chunxiu, Berhane Adere and Lornah Kiplagat set the early pace

Kiplagat passes the halfway point in first place, clocking a time of 1:09.58 ahead of Adere and Zhou

She fades, however, allowing Zhou to break at the 22-mile mark and win in two hours, 21 minutes and 38 seconds

With Wami and Constantina Tomescu-Dita taking second and third, Mara Yamauchi's sixth makes her the best-placed Briton

The top male athletes lead off the rest of the field at 0945 BST with Haile Gebrselassie and Paul Tergat set to challenge

At just over 12 miles, the pacemakers lead the way over Tower Bridge with Gebrselassie and Felix Limo just in front

Gebrselassie drops out with seven miles to go, leaving Limo and Martin Lel to lead the way in the closing stages

A group of six runners approach the Mall with Lel eventually edging home in two hours, seven minutes and 41 seconds

In the wheelchair events, British athletes have a superb day with Shelley Woods and David Weir both winning
