ALL-INN means from ALLGÄU to INNSBRUCK. This point-to-point route runs from Buching, Germany, across the Allgäu and the Ammergauer Alps, and finishes at the famous "Goldenes Dachl" in Innsbruck, Austria. Along the way, the route passes through beautiful alpine towns such as Garmisch-Partenkirchen, Mittenwald, and Scharnitz, which also provide opportunities for (self-)support. Covering just over 100 kilometers with more than 4000 meters of ascent and about 4400 meters of descent, it traverses varied alpine terrain including forest trails, open ridgelines, and high mountain passes. The course reaches a maximum elevation of about 2,280 meters and descends to the valley floor of Innsbruck at 579 meters.
The route combines long climbs (especially the last climb), technical descents, and scenic sections through alpine meadows and rugged mountain landscapes. It links multiple valleys and offers expansive views of the surrounding peaks while maintaining a clear directional flow southward toward Innsbruck. The mix of sustained elevation gain and descent makes this a demanding but rewarding alpine ultra-distance challenge.
