Skeleton is a winter sliding sport in which a person rides a small sled, known as a skeleton bobsled (or -sleigh), down a frozen track while lying face down (prone). Unlike other sliding sports of bobsleigh and luge, the race always involves single riders. Like bobsleigh, but unlike luge, the race begins with a running start from the opening gate at the top of the course. The sport (and the sled) were named from the bony appearance of the sled.
Previously, skeleton bob appeared in the Olympic program in St. Moritz, Switzerland, in 1928 and again in 1948. It was added permanently to the Olympic program for the 2002 Winter Olympics, at which stage a women's race was added.
