David Cameron has put on his running shoes to raise money for Sport Relief.
The Prime Minister and wife Samantha Cameron took part in a one-mile charity run in Oxford, as part of The Sainsbury's Sport Relief Games.
After the event, David Cameron said: "Sport Relief brings together some of the best things about Britain - we are a great sporting nation, but also one of the most generous countries when it comes to contributing to good causes.
"This is the third time I have run the Sport Relief mile and I am delighted to have taken part in such a fantastic event that is bringing people across the UK together to get active, raise money and change lives."
While the Prime Minister turned out in a tracksuit top and shorts, his wife got into the spirit of the event wearing a bright red onesie and Sport Relief headband.
