Monte Rosa Walserwaeg by UTMB
Monte Rosa Walserwaeg by UTMB is listed from Thursday 15 July 2027 at Gressoney-Saint-Jean in the Aosta Valley, a UTMB World Series event with 20K, 50K, 100K and 100 Miles distances. The 2026 edition ran from 17 July, so mid-July is the slot.
The race takes its name from the Walser paths, the old routes of the German-speaking communities that settled the high valleys around Monte Rosa, and the courses follow them across the passes between Gressoney, Alagna and Champoluc. This is high alpine terrain: the long distances go well above 2,500 m and July snow on the passes is possible.
Running Stones from Monte Rosa count toward the UTMB finals in Chamonix, which is three weeks later and a valley away, so a number of athletes use it as their final long run. Turin airport is about two hours by road. Registration is on mrww.utmb.world.
