<Tr> <Th> Olympic </Th> <Td> since 1924 </Td> </Tr> <P> Bobsleigh or bobsled is a winter sport in which teams of two or four teammates make timed runs down narrow, twisting, banked, iced tracks in a gravity - powered sleigh . The timed runs are combined to calculate the final score . </P> <P> The various types of sleds came several years before the first tracks were built in St. Moritz, Switzerland, where the original bobsleds were adapted upsized luge / skeleton sleds designed by the adventurously wealthy to carry passengers . All three types were adapted from boys' delivery sleds and toboggans . </P> <P> Competition naturally followed, and to protect the working class and rich visitors in the streets and byways of St Moritz, bobsledding was eventually banned from the public highway . In the winter of 1903 / 1904 the Badrutt family, owners of the historic Kulm Hotel and the Palace Hotel, allowed Emil Thoma to organise the construction of the first familiarly configured' half - pipe' track in the Kulm Hotel Park, ending in the village of Cresta . It has hosted the sport during two Olympics and is still in use today . </P>
