Wherever they began, sled races quickly became popular.The famous Cresta Run, named after the Swiss town near the base of its course, was built in 1885 using snowbanks.The first organized competition was in 1898, hosted by the first bobsled club in nearby St.Moritz (a city in Switzerland)．It was then that sledding began to separate from the luge to include two new sports: bob sledding, and skeleton sledding (俯式冰橇)． Cresta Run is considered the birthplace of the skeleton, a particularly daring form of sledding.Unlike the luge, where competitors ride feet-first on a sled with metal runners, the skeleton sledding is a steel sled with a slim appearance.Riders lie down on the sled headfirst, then drop suddenly down an ice track.Bobsledding, meanwhile, involves teams of two to four in which the person in front controls directions and the player in back brakes when needed.It earned its name after competitors started swinging back and forth to speed up the sled. Bobsledding initially overtook skeleton sledding in popularity, becoming one of a handful of sports played at the first Winter Games in 1924.The skeleton sledding was limited to the Cresta Run for decades because other bob runs around the world were not built for the steel skeleton sled.But in the 1970s, adjustments were ma
