The Jump 2015 contestants are preparing to take on Snow Cross tonight - and it promises to be one of their most brutal experiences yet.
A brand new event to the show, it's sort of The Jump meets Total Wipeout - an epic course sculpted out of thousands of tonnes of snow, full of sharp turns, steep inclines and obstacles that the celebrities have to skirt around.
But to make it even more dangerous, they'll be doing it three at a time, going at speeds as fast as a car - and injuries are almost guaranteed, the most common being a broken coccyx. Ouch!
Watch a preview of the Snow Cross below, and tune in to Channel 4 at 8.00pm tonight to see how the stars cope on the slopes...
