Rylan Clark, Oti Mabuse and Emma Willis share freezing night in Scottish mountains for Comic Relief

Rylan Clark, Oti Mabuse and Emma Willis have told of the freezing conditions they are currently facing while tackling a Scottish mountain climb for Comic Relief.

Former Big Brother hosts Clark and Willis have joined forced with Dancing On Ice judge and ex Strictly dancer Mabuse to raise money in a Red Nose Day challenge where they are trying to reach the snow-capped summit of Cairngorm mountain.

The trio set out on Wednesday and camped overnight in sub-zero temperatures, before pushing on with their 40lb (18kg) backpacks on a night of little sleep.

Clark told the PA news agency on Thursday: “My body is shot. I’ve managed to somehow bruise my face (and) my collarbones from the rucksack so today carrying that (will) be quite difficult.

“I’ve not actually slept, which is quiet gutting because my… sleeping bag didn’t fit me. It’s been a bit of a nightmare so far.”

Asked if he thinks he can make it on the second day, he said: “I’ve not really got a choice… in an ideal world, I would just get on a plane and go home, but then I’ve not done the challenge so I need to just keep going.

“Luckily, the girls have slept, so I’m sure they’re going to be dragging me through today.”

The Circle presenter Willis said that they were “too scared” to leave the tent from 7.30pm until 6.30am due to outside temperatures being around minus 2C.

She said: “I feel like I’ve been awake every hour because every time you turn over you wake up so it’s kind of delirious asleep. I think I’ve slept but actually I feel like I’ve been awake all night.”

She added: “So we’ve kind of had a really good downtime from (the backpacks) but I think the minute we put them on this morning, it’s going to be pretty savage again.”

Mabuse added: “When we got to camp, I fell to my knees and I felt like crying at the end of the day one; day two is even more walking.”

The trio still need to reach the summit of the mountain, which is 4,085ft (1,245m) above sea level.

Mabuse said it has been “quite hectic” for her as she finished judging ITV’s Dancing On Ice on Sunday and then got ready to hike the mountain this week.

She added: “I’m (going to) hope that we will be fast enough and we actually make it but, you know what, it’s what I do. I’m (going to) show up anyway (on Sunday for the show) and I’m (going to) give 100% of my best.

“I feel like I’m (going to) struggle. I feel like there’ll be a lot of pep talking. I had to put on an audio book to kind of disappear and go into my mind so that I can get over it.”

A documentary, Frozen: Emma, Oti and Rylan’s Red Nose Day Challenge, will air on BBC One and iPlayer in the run-up to the charity day on 17 March.
