Desert Trek for Red Nose Day

Embarking on the toughest physical challenge of their lives, nine celebrities will attempt to cross one of the world's most inhospitable deserts in Northern Kenya to raise cash for Comic Relief. The brave trekkers are aiming to raise as much cash as possible which will help people living unimaginably tough lives both across Africa and the UK.

It could even help to prevent thousands of people in Africa from going blind - something which affects many people living in the region where the trek is taking place. Every minute, a child goes blind somewhere in the world and the effect is truly devastating. Tragically, up to fifty per cent of all children who lose their sight will die within two years.

What makes these figures even more astonishing is that eighty per cent of all blindness is preventable and just £5 could pay for a sight-saving operation for someone in Africa who's suffering from a debilitating eye condition called trachoma.

You can donate to Comic Relief right now by texting the word DESERT to 70011.

Texts cost £1 plus your standard network message charge and the whole £1 goes to Comic Relief.

You must be 16 or over and always ask the bill payers permission. Full terms and conditions are below.

Its going to be a gruelling challenge - and you'll be able to hear from Scott and all the celebrities (including Kara Tointon, Olly Murs, Dermot O'Leary, Ronni Ancona, Craig David and Nadia Sawalha) from Monday 21st February on Radio 1 as they trek across the desert.
