In the run up to Red Nose Day on Friday 13 March, The Big Red Nose Climb follows a host of celebrities as they embark on a colossal ascent of Mount Kilimanjaro. This documentary follows Alesha Dixon, Ben Shephard, Cheryl Cole, Chris Moyles, Denise Van Outen, Fearne Cotton, Gary Barlow, Kimberley Walsh and Ronan Keating as they do Summit Funny For Money and undertake the climb of a lifetime to raise funds for Comic Relief.

At 19,340 feet above sea level, Mount Kilimanjaro in north-eastern Tanzania is the tallest mountain in Africa and the highest free-standing mountain in the world. The celebrity climbers are undertaking an exhausting eight-day trek and The Big Red Nose Climb will be there to capture every gruelling moment – recording every bump, slip and trip from the base camp to the summit.

The team’s incredible efforts will raise money to help change lives across Africa and the UK. In particular they will be exploring how they can help tackle malaria, which kills a child every 30 seconds across Africa. The disease is the leading killer of children in Tanzania.

With money raised through this extraordinary event, Comic Relief will be able to provide nets that can prevent potentially fatal mosquito bites in Africa, as well as helping extremely vulnerable, poor and disadvantaged people in the UK.
