As reality show challenges go, this one is pretty extreme. Well, it's no eating kangaroo balls in the jungle, but intense all the same. This new series sees 12 celebrities battle it out in some of the most challenging winter sport disciplines, including speed skating and giant slalom. Sounds a bit more difficult than a few twirls on Dancing On Ice anyways. Taking to the slopes in Austria are Steve Redgrave, Ritchie Neville, Darren Gough, Sinitta, Marcus Brigstocke, Amy Childs, Nicky Clarke, Kimberly Wyatt, Henry Conway, Anthea Turner, Laura Hamilton and Melinda Messenger, and each night two of them face a live ski jump to keep their place in the competition. So... basically all the usual suspects to appear in a 'celebrity' reality show, but their challenges sound legitimately terrifying - so on this occasion, will have to say fair play for taking part. Davina McCall and Alex Brooker present.
