Riaño Trail Run

About this event

The Riaño Trail Run offers a genuine mountain adventure across three days in northwestern Spain's wild landscapes. Runners tackle stages ranging from 21.5km to 36km through three stunning protected areas: Fuentes Carrionas, Picos de Europa, and Montañas de Riaño y Mampodre. The semi-autonomous format means managing resources while moving through remote alpine terrain — this is raw trail running at its finest. Participants can choose their challenge level: a single day (26.1km), two consecutive stages (47.6km total), or the full three-day experience (84km). With its rugged mountain character and commitment to authentic trail running, this event attracts seasoned runners looking for something beyond the ordinary. The stunning natural parks provide a constantly changing backdrop of limestone peaks, deep valleys, and high mountain passes.
