Will Snow Hit London Marathon On Sunday?

Runners and spectators at this weekend's London Marathon could have to deal with a fresh challenge for the first time in the event's 35-year history – snow. Weather forecasters say it is possible that showers sweeping the country on Sunday could include sleet or even wet snow over London. Celebrities including former Olympic champion Dame Kelly Holmes, Top Gear host Chris Evans and ex-England footballer Danny Mills will be among those hoping predictions of snow are off the mark.
