This week, the celebs had to ski down a 350 metre course full of obstacles including a 'wu-tang', rollers, kickers and a 'cheese wedge' finish.
Before that, they faced a 'speed ski' mini event, the results of which would decide who raced each other on the ski cross.
Spencer Matthews scored the fastest speed, 62.8 km/h, and took on joint third-placers Gareth Thomas and Louis Smith (both 62.2 km/h).
Runner-up Sir Bradley Wiggins (62.4 km/h) would also have joined them, had he not been forced to quit the competition.
Louis ended up winning their race, while Gareth took a tumble and crashed in to Spencer.
Fellow rugby star Jason Robinson (61.9 km/h) then beat Emma Parker Bowles (61.8 km/h) and Amy Willerton (61.7 km/h), with Amy trailing in last after suffering her own slip-up.
Heat three had a surprise winner, with TOWIE's Lydia Bright - who had the slowest speed ski score of 60.6 km/h - overtaking early leader Kadeena Cox (61.6 km/h) and Jade (60.9 km/h).
As Caprice was taken ill before the show went on air, she did not take part and was given a bye to next week.
The three winners then went head-to-head, with Louis claiming his third mini cowbell trophy as the overall champion.
As always, the losers had to fight to remain in the competition on the ski jump. For Gareth and Jade, it was the first time they had to jump live on air.
Emma escaped this fate after beating Kadeena in a second-chance race - but due to his crash, Spencer was unable to take part in any further events.
Therefore, he had to rely on the result of a contingency jump pre-recorded before the live show.
