Dahu Trail 2026

The Dahu Trail is a vertical alpine unsupported ultra-cycling adventure. It will take you on a journey through the high altitudes of the Western Alps. The route will cross the borders between Italy, France, and Switzerland eight times.
This event was born from a simple idea: adventure doesn’t need to be found far away. Our desire is to offer an epic challenge, in the spirit of friendship, respect, smiles, and grinta that bring us together.
