In September 2026 I am planning a Trans Alps traverse from Chamonix in France via Switzerland to Innsbruck in Austria covering 670km / 43000m elevation gain over 18 days (35km/day) across 32 mountain passes (“Cols”). This is part of the Trans Alpina route (1900km, 109km+) which goes across the entire alps from Monaco (West) to Trieste (East) and requires about 2 months to complete.
Plan is to go lightweight (4kg gears + resupply food along the way) and fast (35km/day). Below are the major food resupply points along the way:
You can download below GPX files in nakarte.me to review the route:
