About the Event

Run with purpose and passion at the Gondo Marathon on August 8-9, 2026. This unique two-day double marathon on the Simplon Pass is a powerful tribute, born from a historic landslide, that challenges you across 84km of wild Valais trails. Away from the crowds, the event fosters a profound sense of community, offering a pure mountain running experience on single tracks through imposing gorges and over high passes. The Gondo Marathon is more than a race; it's a heartfelt journey of remembrance and resilience, connecting you deeply with the landscape and its history.
