A red-jowled David Cameron braved muddy streams and wet marshes as he took part in the Great Brook run in Chadlington, Oxfordshire.

Panting and sweating, the PM pounded the British countryside for the fun run, at one point no less than ankle-deep in swirling waters.

The track saw Cameron on his hands and knees as he navigated through the babbling brooks of the Cotswolds, but despite the undignified position he managed a boisterous smile for the cameras.

After a mile on the rough terrain the PM eventually made it to the finish line, a bandage wrapped around his slender knee, his black and neon green Nike top streaked with mud.

Cameron didn't win the fun run, but as any politician will tell you, it's not about winning, it's about taking part.

All proceeds from the fun run go to The Friends of Chadlington School, a charitable group which supports the local primary school.
