The Jump - Season 4

Channel 4's epic celebrity winter sports competition returns. The contestants include Bradley Wiggins and Robbie Fowler, with tonight's live challenge being the parallel slalom.

The 13 brave celebrities race downhill on snow skates in the treacherous snowcross event. The losers then face possible elimination by The Jump.

The remaining celebrities take on the nerve-shredding skeleton, racing face-first on a sled down a twisting ice track. One of the losers then faces elimination by The Jump.

The celebrities tackle two winter sporting disciplines - speed ski then ski cross. Fast-paced and adrenaline-packed, the ski cross race is one of the hardest events on the slopes.

The competitors battle it out for a place in the final. If the Ski Jump itself is a long jump, then the Air Jump is the high jump, and to progress to the next round the competitors need to jump as high as they can in this event. Then there's the Giant Slalom - longer and steeper than the Parallel Slalom. The celebrities go faster with the Giant Slalom than on any other course in the competition, as they bid to stay in contention for being crowned The Jump Champion 2017. Presented by Davina McCall.

The remaining celebrities battle it out in the live final, to be crowned winner of The Jump 2017 and take home the coveted cowbell trophy. Over the last five weeks the competitors have honed their alpine skills and tonight they will have to dig deep as they go head to head in the Snow Cross and Ski Cross races, before heading to the top of the Ski Jump for the last time. Only one person can win. Who will jump the furthest? Presented by Davina McCall. Exec Pros: Melanie Leach, Andrew Mackenzie, Caroline Davies;
