Their ordeal will be broadcast live on CH4 and ordeal is no understatement for those sitting on the seat of the in-run of a ski jumping training hill – this really will be a gruesome moment for even the bravest of them. As well as Sir Steve Redgrave there will be Ritchie Neville, Anthea Turner, Marcus Brigstocke, Amy Childs, Sinitta, Nicky Clarke, Henry Conway, Kimberly Wyatt, Melinda Messenger, Darren Gough and Laura Hamilton competing in this winter sports spectacular in Innsbruck. For those still in one piece after the ski jump the contestants will be competing in bobsleigh, skeleton, speed-skating, slalom skiing and cross-country.
