On the first day, you run from Gondo through the imposing Gondo Gorge to Simplon village, then to the Simplon Pass and the highest point on the Bistinen Pass (2417 m above sea level), into the Nanz Valley and through the Saltina Gorge to Brig. In memory of the first event in 2002, when the bridge was swept away by the storms, the mountain stream is crossed 2 km before the finish (secured by the fire brigade).
On the second day, the route leads from Ried-Brig along the legendary Stockalperweg and the Talweg Ganter to the Simplonpass, then down to Simplon-Dorf and Gabi, where a steep climb to the Furggu awaits. Through the Zwischbergental valley back to Gondo.
Mostly you walk on single trails, again and again on alpine paths and only very rarely on asphalt. You experience wild valleys, sparse mountain forests, colourful flower meadows, alpine pastures and southern-looking pine forests.
The first day can also be run as a single marathon (on Saturday).
For the anniversary, a relay is offered in which the team members themselves decide how to split the distance.
