All-star team ride for Sport Relief

He's already swum the English Channel and now Little Britain star David Walliams is to tackle the journey from John O'Groats to Land's End by bike.

Walliams is doing the 875-mile haul for Sport Relief in the company of comedians Jimmy Carr and Miranda Hart, and telly presenters Fearne Cotton and Davina McCall.

According to the Sun, the team reckon they can do the journey in four days by cycling in relays. But grim little B&Bs at the end of each day are out of the question - a luxury bus will accompany them at all times.
