A luge /luːʒ/ is a small one- or two-person sled on which one sleds supine (face up) and feet-first. A luger steers by using the calf muscles to flex the sled's runners or by exerting opposite shoulder pressure to the seat. Racing sleds weigh 21–25 kg (46–55 lb) for singles and 25–30 kg (55–66 lb) for doubles. Luge is also the name of an Olympic sport. The first recorded use of the term "luge" dates to 1905 and derives from the Savoy/Swiss dialect of the French word luge, meaning "small coasting sled".
