bobsledding

A venue for recreational or competitive gravity-powered sledding by one or more riders on a snow or ice course.

Bobsledding is a winter sport in which one or more persons ride a gravity-powered sled along a defined or open course, often with twists, humps, drops, or obstacles. It may be used for recreational or competitive bobsledding.

Gravity supplies the motion of the sled, and one or more people can ride it. The existing usage includes recreation as well as competition.

The course can be defined or open and can include changes of level or direction. A particular team size is not required by this definition.
