They are best known for being the face of prime time shows, accustomed to glamorous wardrobes and mingling with the stars.
But Emma Willis, Rylan Clark and Oti Mabuse will be out of their comfort zone in their Red Nose Day Challenge.
The trio will be worlds away from their comfortable lives in television studios as they brave the elements to climb to the top of Cairn Gorm mountain in the Scottish Highlands, all for the charity, Comic Relief.
The expedition will be broadcast in a BBC special on Tuesday and it’s sure to be entertaining to watch with Rylan as he’s “never been camping in my life”.
Before the show, here’s everything you need to know, from how to donate to more information about their overwhelming expedition.
No Mountain High Enough: Emma Willis, Rylan Clark and Oti Mabuse will push themselves out of their comfort zone in their Red Nose Day Challenge
What is the Emma, Oti and Rylan Red Nose Day Challenge?
In the challenge, Emma, Oti and Rylan will face off against a wild camp and, equipped with ice axes and crampons, they will battle the ever-changing elements to reach the top of Cairn Gorm Mountain.
The trio spend three days and two nights trekking through the brutal landscape of Cairn Gorms National Park in the Scottish Highlands, immersed in a vast winter landscape with no roads and few shelters.
Setting out from Braemar, the party becomes completely self-sufficient, relying only on what supplies they can take with them.
Rylan, 34, who is already in Scotland to start training, doesn’t exactly see himself as a Bear Grylls-style outdoors extraordinaire.
He said: ‘I’ve never been camping in my life. I have never slept in a tent. I have never worn camping clothes. The only camping I do is camping on a Saturday night!
He continued: I think the hardest part for me throughout this whole challenge is going to be… the whole challenge.’
‘I’m not going to lie to myself, this is not what I am used to, and this is not what I would choose to do. But here I am, and I just hope I get out of this in one piece and not lose any varnish in the snow.

‘The only camping I do is camping on a Saturday night’: TV personality Rylan admitted he doesn’t have a lot of outdoor experience
Challenge Accepted: The trip spends three days and two nights hiking and camping in the brutal landscape of the Cairngorms National Park in the Scottish Highlands.
The presenter, however, recognized, despite the arduous task ahead, the importance of the challenge.
He said: ‘I think the thing that will carry me through the whole challenge is obviously the girls and knowing that we’re doing it for a great cause. The better we do, fingers crossed, the more money we’ll raise.’
“Knowing where the money is going to definitely go will be my motivation when I’m ready to throw it all away and call in the helicopter.”
Travel companion and TV presenter Emma, 46, seemed a little more optimistic about the trek.
She said: ‘I said yes to taking on this Red Nose Day challenge for a couple of reasons. The first is when Comic Relief asks, you should always say yes. The second is that I love to do things that take me out of my comfort zone, and earlier this year, I promised myself that I would do the things that scare me.
Even the Voice UK presenter, however, saw that this would be no easy task.
It will be difficult. And the more I talk about it, the more difficult it seems. I think you have to switch your brain to ‘there’s no choice but to succeed’ mode.
“I was able to visit a Comic Relief funded project a few days ago that supports homeless youth and they were phenomenal, so they will be the people I have in mind.”
