The celebs have already flown into Inssbruck, Austria to start their training ahead of the start of the show, on 26 January.
It will be broadcast live over nine nights, with each programme showing the highlights of the day’s event.
The two individuals with the lowest scores in that event will then have to compete in a live ski-jump jump-off to see who will be eliminated from the show.
The Jump is being presented by Eddie the Eagle, with Winter Olympics star skier Graham Bell and skeleton gold medallist Amy Williams among those training the hopefuls.
