Autumn Trail Races 2026 — September, October & November

Autumn is the second great season for trail running in Spain. After the summer break, September kicks off with races where heat eases and forests begin turning ochre and crimson. October and November offer perfect conditions for long distances: mild temperatures, good daylight hours, and firm terrain after the dry summer. It's the preferred time for ultras along the Cantabrian coast, races in Mediterranean natural parks, and the year's final events in the Canary Islands before winter season. If you're looking for races with autumn landscapes, pleasant weather, and fewer crowds than spring, here's your selection with complete Pack 360.
