Downhill run
The traditional trails of the resort were largely used for the men's and women's Downhill Race, as their general characteristics seemed satisfactory. It was however necessary to calibrate them, to get rid of bottle necks, and rock steps, to blow up rock masses, to cut down trees, etc...Some particular points demanded more important work:
— in the upper third of the Men's Downhill, two rocky ridges were split up to vary the tracing, just after the shoulder of the "Grand Couloir", and at the branch of "Arbre Mort". Another ridge was cut at the beginning of the "false plateau" called "des Grottes", and the "Couloir KRIEG" was banked up.
— on the Women's Downhill trail, a rocky ridge was split up at the start of the "Grand Couloir", and the "Arbre Mort" bend was completely remodelled. An embankment of 12,000 m3 was made at the Vernon stream, to limit the length of a "false plateau" before the finishing schuss.
Slalom
The slopes necessary for the organization of a special slalom must present relatively stiff characteristics and the equipment of a slalom stadium in the immediate proximity of the finishing zone required very important earth works; the natural terrain was in fact cut by a deep ravine, which had to be filled in, and marked by two rocky ridges which were blasted.More than 200,000 m3 of rock embankment had been made before the International Weeks. During these events, the summit zone of the Men's special slalom was judged to be still too flat and a starting hillock, 20 m High (35,000 m3 of rocky material) was heaped at the summit of this trail during the summer of 1967.
The work begun in July 1967 was completed in three months. It was financed by the Department of the Isère, which received a grant of 80% from the Ministry for Youth and Sport. It amounted to 4,400,000 F.
