White marathon (1935)

Documentary on one of the first editions of the Trofeo Mezzalama, the highest ski mountaineering race in Europe, at more than 4,200 meters above sea level, which takes place on the glaciers of Monte Rosa, from Breuil to Gressoney-La-Trinité, crossing the summits of Castor (4,199 meters) and Nez du Liskamm (4,100 meters). The film recounts the last hours of feverish preparation before the start, the teams preparing for the race linked in ropes, then follows the stages of the competition by following the groups of skiers from a plane. Created in 1933, the Trofeo Mezzalama was contested until 1938, before falling into oblivion during the war. A second version was organized from 1970 to 1973. A third biannual version has been organized since 1997.
