Backyard Ultra Valais

03 April 2026

Backyard Ultra Valais - Ardon

In the heart of the Valais, in the Ardon region, this running race offers a complete immersion into the world of the Backyard Ultra. An atypical ultra-endurance format, based on consistency, mental strength and a collective atmosphere, with a start and finish at the same place, the Couvert des Aprages.

The course takes place over a 6.7 km loop, to be completed every hour. As long as several riders are still in the running, the race continues. The course alternates footpaths and rolling roads, With a moderate gradient, it is accessible but demanding over time.


The Backyard Ultra concept

The principle is simple and formidable:
