Snocross (also snowcross) is a racing sport involving racing specialized high performance snowmobiles on natural or artificially-made tracks consisting of tight turns, banked corners, steep jumps and obstacles. Riders race at speed of up to 60 miles per hour (96 kilometers per hour). Jumps are up to 30 feet (9 meters) tall, so riders travel up to 130 feet (40 meters) before they touch the ground.
