Thousands Set To Complete London Marathon
Runners including Princess Beatrice, a host of celebs, and fun runners are taking part in the London Marathon
More than 36 thousand people will take on the 26 mile course through the capital's streets - raising money for countless charities.
Four brothers will make a noble attempt at running the 26 mile course by donning full suits of plastic armour.
The Cameron brothers are running in memory of their father Alastair, who died of a heart attack in 2004 at the age of 70.
And they will be chasing their very own Lady Guinevere along the route.
