Cameron runs in charity mud race

Version 0 of 1.

Conservative Party leader David Cameron has taken part in an annual charity mud race in his west Oxfordshire constituency of Witney.

He joined a record number of people on the fourth Great Brook Run in the village of Chadlington on Sunday.

Runners on the one-mile (1.6km) cross-country course have to tackle freezing water and pass through a tunnel.

Mr Cameron said: "The main thing is to complete the run, survive and to get home to have lunch."

He finished the course in about 15 minutes, while the winner made it in 8.5 minutes.

Mr Cameron added: "I enjoyed it. It's for charity and it's a good thing to do, it brings everyone together, it's a nice day out, 'ish'.

"It's called a brook, but it is more like a river and it is quite cold in there."

The race started at the Tite Inn and wound its way through muddy fields before finishing back at the pub.

Mr Cameron was met by his wife Samantha after the run, when he and the other competitors were given a medal for taking part.
