A bob run is an extremely complex construction. The one at Cesana Pariol is 1.5km (0.9 miles) long, and has three entrances, 19 curves (11 left and eight right) and a height difference of 125m.

The maximum speed reached in bob races is about 130kmph (81mph). The run contains a labyrinth of cooling pipes with a total length of about 87km (54 miles). The liquid is regulated via sensors under the thick layer of ice. It is a technological masterpiece guaranteeing a constant ice thickness of 5 to 10cm.

Vittorio Salusso and the German bob run expert Udo Gurgel, the Italian engineer Franco Pavan and the Italian bobsleigh manager Ivo Ferriani cooperated on the construction of the bob run. Roman ruins were discovered during the construction work. Fortunately, they were found not to be particularly valuable, so it was possible to continue with the project.

However, during the first trials on the run, several bobsleighers were catapulted out of the course and were badly injured. Work on the run was almost called off. This would have meant that the events would have to be held elsewhere. But it finally proved possible to make the bumpy course more even and to change one of the curves.
