Marathon des 3 Pays du Rhin 2026

The Marathon des 3 Pays du Rhin is a road race that takes place around Basel and the Rhine border region, connecting Switzerland, France, and Germany. It is known as a “3 in 1” event because participants run through Basel, Saint-Louis, Huningue, and Weil am Rhein, crossing national borders. The event has offered 5 km, 10 km, half-marathon, and full marathon distances, along with a duo option for pairs tackling the longer distances. The course begins in Basel, a Swiss city on the Rhine. It then proceeds through the adjacent border towns of the Upper Rhine region, making it a cross-border event on public roads. The French segments run through Saint-Louis and Huningue in the Haut-Rhin department, and the German section goes to Weil am Rhein. While described as an established event, sources indicate the marathon has had its final edition, suggesting it is a race with a distinct local history rather than a recurring annual fixture.
