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. Racing sleds weigh 21–25 kilograms (46–55 lb) for singles and 25–30 kilograms (55–66 lb) for doubles. Luge is also the name of an Olympic sport. Lugers can reach speeds of 140 km per hour (87 mph). Manuel Pfister of Austria, reached a top speed of 154 km per hour (95.69 mph) on the track in Whistler, Canada prior to the 2010 Vancouver Winter Olympics. Lugers compete against a timer and on artificial tracks are timed to a thousandth of a second, making luge one of the most precisely timed sports in the world. The first recorded use of the term "luge" is 1905, from the Savoy/Swiss dialect of French "luge" meaning "small coasting sled", and is possibly from a Gaulish word with the same root as English sled.
