Half-pipe skiing is the snow sport in which athletes compete on performing tricks while riding on a half-pipe wearing snow skis.
A halfpipe is a U-shaped ramp or course which has been purpose-built for sporting use. It’s typically used by skateboarders, BMX riders, snowboarders and skiers, who use the ramp to propel themselves into the air, where they’re able to pull tricks before landing again and continuing on to do the same on the other side of the pipe.
It’s great fun to watch. Each athlete drops into the halfpipe individually and completes a run down the length of the pipe, doing as many jumps and tricks as he or she can manage, to the best of their ability, and then whoever comes out the pipe at the bottom with the best score wins.
