Skeleton is a winter sport featured in theWinter Olympics where the competitor rides head-first and prone (lying face down) on a flat sled. It is normally run on an ice track that allows the sled to gain speed by gravity. It was first contested at the1928 Winter Olympics inSt. Moritz and again in1948 Winter Olympics, after which it was discontinued as an Olympic sport.
Skeleton is so-named as the first metal sleds introduced in 1892 were said to resemble a human skeleton. The sport is similar to, but not to be confused with,luge, another form of sled racing where the competitor rides on the back and feet-first. Often using the same courses, the racing physics are not identical.
