The Mezzalama Skyrace was an international high altitude endurance race competition, defunct in 2008,[1] in upper Valtournenche Valley, in the Aosta Valley, Italy. The summer event in the Monte Rosa's massif has been carried out annually by the Mezzalama Trophy association since 2000, and was also named in honor of the mountain guide Ottorino Mezzalama.
The starting point is in Saint-Jacques (1,680 metres a.s.l.), a hamlet in Ayas. The participants pass Verraz (2,380 metres a.s.l.), Saint-Oyen, and then the Blue Lake (French: Lac Bleu), then they take back the main track and meet to the moraine of the Grand Glacier of Verraz (French: Grand glacier de Verraz, Italian: Grande Ghiacciaio di Verra) to reach the Refuge Ottorino Mezzalama, which is the turning point of the circuit. Total course length is 15 kilometres with a 1,356 metre altitude difference, to be finished in a maximum time of 4 hours.
