The largest canton in Switzerland, Graubünden brings together the Engadine, Davos and Chur, with high-altitude trails, a swimrun, a backyard ultra and mountain passes for cyclists, from June to September, for all levels.
The largest canton in Switzerland, Graubünden boasts more than 150 valleys, hundreds of lakes and peaks that rise above 4,000 m 🏔️. For races in Graubünden, there is no shortage of choice, from the trails of the Engadine to the alleys of Chur, the oldest town in the country. Three languages coexist, German, Romansh and Italian, and each valley keeps its own identity.
The territory reads like a relief map. In the north, the Rhine valley and Chur form an urban gateway. In the center, Davos and Lenzerheide open onto the alpine pastures and the great ridges. In the south, the Engadine and Piz Bernina tower over the lakes, while Mesocco already looks toward Italy. The climate remains dry and sunny, with a racing season that runs from June to September. Winter, for its part, belongs to skiing 🎿, giving you time to prepare for the following season.
The Graubünden race calendar opens in June with the Swiss Irontrail in Savognin and the Bernina Ultraks in Pontresina. July brings the Engadin Ultra Trail in Samedan, the Race Across Switzerland in Klosters and the Ötillö Swimrun Engadin in Silvaplana 🏃. In August, the Transalpine Run leaves from Lenzerheide, while the Backyard Ultra Chur puts your nerves to the test in Chur. To choose your discipline, head to the pages on trail running in Graubünden or mountain races in Graubünden.
The Glacier Express crosses the canton while boasting of being the slowest express train in the world 🚂, a lesson in patience that ultra runners know by heart 😄. Dario Cologna, four-time Olympic cross-country skiing champion, is a reminder that endurance is an old tradition here. From a 5 km valley run to a multi-day ultra, everyone will find their race according to their level and their appetite for altitude. To broaden your horizons, the mountain race calendar in Switzerland awaits on the other side of the passes.
A next-gen platform helping sports enthusiasts of all levels discover territories and heritage through races tailored to them.
