The Olympia Bob Run St. Moritz-Celerina, at 1,800 m above sea level, is not only the oldest bob track, but also the only natural ice run in the world. Within three weeks, the track builders from the South of Tyrol create it each year anew. The team models the run by hand and thus without big machines.For more than hundred years, this 1,722 m long ice sculpture excites athletes, fans, spectators and holiday visitors. All in the heart of purest nature. In the course of its 125-year old history, it has staged events for two Olympic Winter Games, as well as 24 World Championships.
