roller skating
A rink or other space for roller or inline skating, including flat, banked, and obstacle-equipped surfaces.
A roller skating facility is a rink, arena, or other space designated for roller skating or inline skating for recreational, training, or competitive purposes. It includes all forms of skating on shoes with wheels. The facility may be flat, or feature a banked track, or it may feature ramps, jumps, and other types of obstacles for skaters.
The skates are shoes with wheels, including inline arrangements. Training and competition are included alongside recreational use.
A flat rink is one possible layout. Banked tracks and surfaces with ramps or other obstacles also fall within this usage.
