The Cresta Run is the world's oldest purpose-built bob run, a natural ice track built each winter since 1884 between St. Moritz and Celerina. Riders travel face-down on small steel sleds called "skeletons," reaching speeds up to 140 km/h around the run's famous bends — including the notorious Shuttlecock corner, where ejections are common and celebrated with a bottle of champagne presented by the club.
The track is built by hand each November by the St. Moritz Tobogganing Club from the water of an adjacent stream, which freezes naturally on the channel's walls before being shaped by hand to its characteristic profile. The run is open to fee-paying members and their guests on certain mornings; watching from the Shuttlecock viewpoint on the bank is free and provides all the excitement without any of the risk.
