It is too late to slope off now for the 12 celebrities ski-suited and booted to take part in a new winter sports challenge TV show.
Olympian Sir Steve Redgrave is joined on the slippery slope by stars including Sinitta, Amy Childs and ex-England cricketer Darren Gough.
They will will battle it out in Channel 4's The Jump competing in sports including bobsleigh, skeleton, speed-skating, slalom skiing and cross-country skiing with the worst performers having to brave a huge ski jump to stay in the competition.
Also taking part in hair-raising feats on the snow and ice are former Pussycat Doll Kimberly Wyatt, presenters Anthea Turner and Melinda Messenger and Ritchie Neville of reformed boyband 5ive.
Winter Olympics stars skier Graham Bell and skeleton gold medallist Amy Williams will be among those training the hopefuls.
They will also be coached by daredevil Eddie 'The Eagle' Edwards, who won last year's ITV Splash! highdiving contest, as he teaches them how to ski jump.
He said: ''This competition is as much about mental strength as it is about physical agility. Winter sports are tough to master; it takes skill, guts and determination to get round a course.
''The ultimate test will be the jump itself. I know how hard it can be when the world is watching.''
The show starts on Channel 4 at 8pm on Sunday January 26.
