Richard Hammond, Gary Lineker, Davina McCall, Patrick Kielty and Claudia Winkelman bring together the BBC's biggest brands in a huge celebration to try and top 2006's fund-raising total of ??18 million.

The star-studded night of entertainment includes Sport Relief Does Strictly Come Dancing featuring Mark Ramprakash, Eastenders star Kara Tointon, Elaine Paige and football heartthrob David Ginola.

Jonathan Ross goes head to head with Sir Michael Parkinson for a very special Friday Night with Jonathan Ross as well as taking on Jimmy Carr in a celebrity tennis match at the Albert Hall. Other highlights include Sport Relief Does the Apprentice, the Top Gear team embarking on makeover madness, Leona Lewis performing the Sport Relief single and comedian Alan Carr taking on the Arsenal ladies football team. The golden boy of breakfast TV, Ben Sheppard, squares-up to singer Lemar over three gruelling rounds in the boxing ring, and Jimmy Carr hosts a very special one-off edition of Question of Sport Relief.

The night also sees the culmination of the Sport Relief One Show Challenge as football legend Alan Shearer and Adrian Chiles complete their cycling challenge from Newcastle to London live in the studio, and we find out whether James Cracknell, with the help of David Walliams, can complete one of the most difficult sporting challenges ever as he undertakes a triathlon from England to Africa. Chris Moyles also completes his Radio One Challenge live in the studio.

And as ever, it's up to you the viewer to rise to the challenge to make the difference. The money raised will go towards helping vulnerable people both at home in the UK and across the world's poorest countries.
