A superpipe is a large halfpipe structure used in extreme sports such as snowboarding, freestyle skiing, skateboarding, freestyle BMX and inline skating.
There is no standard definition for a super pipe. However, generally the term "superpipe" is used to describe halfpipe built of snow which has walls over 16ft (5m) on both sides. Other features of a "superpipe" are the width of the pipe is wider than the walls are tall and the walls extend to near vertical. In the FIS snowboard world cup rules the recommended width for 22ft (6.5m) walls is 19.5m. [1] [2]
A superpipe also requires extensive grooming by specialized equipment, for example, a normal halfpipe can be cleaned by a normal snow groomer.
