Join Rob Brydon as he trips the light fantastic amongst the funniest, sweetest and silliest musical sketches and performances from the Comic Relief store cupboard. To make it to the finish line, Billy will have to walk further than he's ever had to before, kayak for the first time in his life and learn how to cycle again for the first time since his crash. But if anyone can do it, Billy can. As a successful racing driver, Billy is already used to pushing the limits of what can be achieved. Each stage of the journey takes place in a different part of the country, with Billy joined along the way by a host of surprise celebrity supporters. (thetvdb.com)
