Chris Moyles will set off on a seven day mountain climbing adventure in Africa with fellow BBC Radio 1 presenter Fearne Cotton and a host of celebs to raise money for Comic Relief.
The pair will climb Mount Kilimanjaro in Tanzania along with Cheryl Cole, Kimberley Walsh, Alesha Dixon, Ben Shepherd, Ronan Keating, Denise Van Outen and Gary Barlow.
Moyles says he only agreed to it because Gary Barlow rang him up and asked him, now he is regretting it, he jokes on the official Red Nose Day video.
The breakfast team climbed Snowdon in Wales at the weekend as a practice.
