Astu Trail 2026

Astu Trail is a mountain running event held in Astudillo, a small town in Palencia, Spain. It is scheduled for late October, with registration opening in early September and closing shortly before race day. The event provides two trail distances: 21 km for those seeking a longer mountain race, and 11 km for a shorter run. The exact route is not specified, but the format is distinctly local trail running, not a road race. The 11 km option is non-competitive, suitable for walkers, newer trail runners, or anyone wishing to participate without aiming for a specific rank. The Ayuntamiento de Astudillo organizes the event, linking it closely to the town rather than operating as part of a large commercial series.
