Designed by Luciano Galli and built from spring 1966, this all-concrete track was the bobsleigh venue of the 1968 Grenoble Winter Olympics, after a test at the 1967 World Championships. Its start sat at 2,030 m and its walls rose to about 4.5 m. The course faced the sun, so the ice melted: three curves needed ammonia or liquid nitrogen cooling, and races were run at night. Ten months after the Games, the Swiss press reported that it would not be reopened, as preparing it cost too much for one or two races; no later race on it has been found.
- Races were run at night to keep the sun off the ice.
- Curves 6 and 9 were cooled with ammonia, and curve 12 with liquid nitrogen.
- Its designer, Luciano Galli, also designed the Lago Blu track at Cervinia.
Today
Concrete fragments of the track can still be seen at the Col du Poutran, at about 1,956 m.
