Swiss Bike-Adventure takes riders on a demanding journey around Switzerland, linking remote valleys, mountain lakes and some of the most spectacular Alpine passes in Europe. Starting and finishing in Andermatt, the fixed route crosses the country’s different linguistic regions, with a short detour into Italy along the way.
The 2027 route covers 1,337 km with 27,230 metres of elevation gain, featuring 15 major climbs. Highlights include the Susten Pass, Grosse Scheidegg, Col des Mosses, Chasseral, Albula Pass, Bernina Pass, Splügen Pass, San Bernardino Pass, Nufenen Pass and Furka Pass. The route is almost entirely paved, with just one short gravel section of approximately 4.3 km near Chasseral.
This is a road-focused endurance challenge where the climbing is relentless. Riders move between high Alpine passes, quiet country roads and scenic lakeside sections, experiencing the contrasting landscapes and cultures of Switzerland along the way.
The event follows a self-supported format: no help from friends or support vehicles is permitted, and riders must rely on commercial services for food, accommodation and supplies. Participants can ride solo or in pairs, with GPS tracking provided by the organiser. There is no overall time limit, leaving riders to manage their own pace and recovery throughout the journey.

Swiss-Bike Adventure's terrain calls for a Endurance Road Bike, ideally running 30-35mm Tubeless tires. On the drivetrain side, a 46/30T-50/34T (2x) chainring matched to a 10-36T cassette gives enough range for the climbing involved.
We rate Swiss-Bike Adventure as Extreme overall. Riders should be ready for mostly smooth, fast-rolling surfaces, relentlessly mountainous, climbing almost the entire way elevation gain, and mild and generally comfortable conditions.
