Ice racing is a form of racing that uses
cars,
motorcycles,
snowmobiles,
all-terrain vehicles, or other motorized vehicles. Ice racing takes place on
frozen lakes or
rivers, or on groomed frozen lots. As cold weather is a requirement for natural
ice, it is usually found at higher latitudes in
Canada, the northern
United States, and in northern
Europe, although limited indoor events are held in warmer climates, typically on ice hockey rinks (motorcycles and ATVs only). Tracks in North America vary from 1/4 mile (~400 m) long ovals to several mile-long road course designs.
