About CollonTrek (Bionaz-Arolla)

The Collontrek is a long mountain race of about 22 kilometers (1,250 meters of positive vertical drop and 1,230 of negative difference in height). 

The route develops along ancient paths used, once, by the neighboring cross-border populations (farmers, smugglers, ...) of the Alta Valpelline (Italy) and Val d'Hérens (Switzerland) who have been able to preserve customs, traditions, and even common languages (Franco-Provençal dialect, the battle of queens, ...).

Collontrek's departure is predicted at the height of the upper crowning wall of the Place-Moulin Dam (1,989 m) in the municipality of Bionaz (Valle d'Aosta-Italy) and then continue up to the Italian-Swiss border coinciding with the Col Collon (3,080 m) and finish at 2,006 m. of Arolla, a Swiss town in the commune of Evolène (Canton of Valais).

The Collontrek runs along the trails that are part of the Matterhorn Tour, the Great Dams Tour and passes near the Tour des Combin. It is a mountain hiking path that runs at high altitudes until it reaches and crosses the Arolla glacier. Even the weather conditions that can be found along the way are typical of the alpine environment with changes in the climate, even sudden, so that in a short time you can pass from beautiful to cold, from wind to fog, from rain to ice and maybe even some Snowflake…. (The race can be classified as a hiking path in the T4 mountain according to the Swiss Alpine Club, EE according to the Italian Alpine Club and red dot according to Spirit Trail).

The characteristics of the route can be summarized as follows: 48% mountain trail, 16% glacier, 30% hiking trails and 2% asphalted sections.

One of the most unusual trail races anywhere, Collon Trek begins in Italy, in the hamlet of Bionaz in the Valpelline region, climbs a high pass, traverses a glacier, and finishes in Switzerland. The race reaches its high point of 3,080 meters when crossing over into Switzerland’s Eringer valley, at Col Collon. Runners use microspikes and other forms of traction, to assist during the glacier section. The run finishes in the village of Arolla, on the Haute Route between Chamonix, France and Zermatt, Switzerland. Collon Trek celebrates the shared culture of these two valleys. The race takes place every other year, with 2016-2018-2020 being off years. So see you in 2019!
