A Winter Olympic sport involving high-speed descent down specially equipped ice tracks on steered bobsleds. The birthplace of bobsleigh is Switzerland. It was there, in St. Moritz, that the world's first bobsleigh club was founded in the late 19th century, where the basic rules were developed. The number of crew members and their gender composition have varied over time. Today, at the Olympic Games, men compete in two- and four-seater bobsleighs; women in single- and double-seaters.
