A Luge is a small one- or two-person sled on which one sleds supine (face up) and feet-first. Steering is done by flexing the sled's runners with the calf of each leg or exerting opposite shoulder pressure to the seat. Lugers can reach speeds of 140 km per hour, and the Guinness world record is held by Tony Benshoof of the United States at a speed of 139.9 km per hour although some athletes, including Sam Edney of Canada and Felix Loch of Germany have reached speeds exceeding 150 km per hour on the track in Whistler, Canada.
