Monte Rosa Walserwaeg by UTMB

A world-class trail on the Walser tracks

The Monte Rosa Walserwaeg by UTMB is the trail running race that has brought the international UTMB World Series circuit to Valle d'Aosta. It takes place in the Monte Rosa area, based in Val d'Ayas and passing through the Municipality of Brusson, along the historic paths that for centuries have connected the Matterhorn slope to that of Monte Rosa.

The meaning of the name: the Walser paths

"Walserwaeg" means "the Walser path". The Walser are a population of Germanic origin, who left Upper Valais in the Middle Ages to settle on the highest slopes of the Alps, particularly in the Lys Valley and Val d'Ayas. Their heritage is still alive in the wood and stone architecture, traditions, and language, an ancient variant of High Alemannic German. Running this trail means traversing eight centuries of human history, through stone villages like Antagnod, Champoluc, and the high-altitude pastures.

Spectacular alpine terrain

The routes wind through perennial glaciers, flowery meadows, larch and fir forests, and the characteristic villages of Val d'Ayas — Challand-Saint-Victor, Challand-Saint-Anselme, Brusson, Antagnod, and Champoluc — always under the gaze of the great peaks of Monte Rosa. It is technical and challenging terrain, ideal for those seeking an authentic high-mountain running experience.

An event for Valle d'Aosta

Entry into the UTMB World Series circuit has placed the Monte Rosa territory and the Valle d'Aosta Region on the international trail running map. In addition to the long races for experienced athletes, the program includes short distances and events for younger participants, making this a widespread celebration of mountain running.
