Comic Relief

To raise money for this year's Red Nose Day, Emma Willis, Oti Mabuse and Rylan are taking on the unforgiving, subarctic terrain of the Cairngorm Mountains in the Scottish Highlands. It's a once in a lifetime challenge, taking place over three gruelling days and two freezing nights, and the trio need to adapt to the elements as they trek through this vast and sometimes dangerous landscape, before attempting to summit Cairn Gorm, the majestic and intimidating mountain that gives the area its name.

Embarking from the historic town of Braemar, the challenge begins with a hero's send-off from locals and the king's personal representative in Aberdeenshire, the lord lieutenant. Carrying heavy, energy-sapping backpacks that contain everything they need, Emma, Oti and Rylan leave the town and toilet facilities behind as they make their way into the wilderness, where the strong winds and steep ascents soon leave them wondering if they have bitten off more than they can chew. A night camping in the freezing rain leaves sleep-deprived Rylan the worse for wear, and after another day facing down the unrelenting elements, the trio arrive battered and bruised at their second camping site in the foothills of Cairn Gorm. Day three is meant to be their attempt on the summit, but the trio wake up to some shocking news.

The UK's biggest night of comedy and entertainment, with hilarious sketches, live performances, big surprises and stunning music acts, all to raise much-needed cash for good causes at home and across the world.

David Tennant is joined in the studio by Paddy McGuinness, Zoe Ball, Joel Dommett and AJ Odudu.

Comedians Flo and Joan perform their mischievous tribute to 35 years of Comic Relief. Oti Mabuse and Rylan Clark return after their epic battle against the elements in the Cairngorms. We celebrate the wonderful Gethin Jones, whose Strictly Fitness: Gethin Keeps Dancing challenge saw him dance for 24 hours with the help of some showbiz pals. And throughout the evening, a series of films highlight incredible and inspiring stories of the people supported by some of Comic Relief's projects in the UK and around the world.
