L'anneau de vitesse
|Full name||Anneau de Vitesse du Sauvay|
L'anneau de vitesse (French: Olympic Oval) was a speed skating venue located in Albertville, France. As of the 2014 Winter Olympics, it is the last outdoor venue to hold speed skating as all following Olympic events have been held indoors. For the 1992 Winter Olympics, they hosted the speed skating events.
The stands which are still up were constructed as an airfoil from aerospace designs. The ice was made using 70 km (43 mi) of piping using R32 and brine refrigeration to cool the track to between −5 and −8 °C (23 and 18 °F) with 4 cm-thick (1.6 in) ice. Before this the surface was covered with 1.20 m (3 ft 11 in) of base sand in order to lay down the piping.
