Izzard on blisters and ice baths

Eddie Izzard tells the BBC's Claire Heald about the state of his legs after embarking on a marathon Sport Relief challenge.

He set off from Trafalgar Square on 27 July in an attempt to run more than 1,100 miles around the UK in seven weeks in support of Sport Relief.

By the time he reaches Trafalgar Square at the end of his run, he will have covered a remarkable 43 marathons in 51 days and passed through all four nations of the UK.
