Trail Races in October in Spain 2026

October paints Spain's trails with autumn colours and offers fantastic racing conditions. Temperatures are cool but pleasant, forests are at their chromatic peak and the days, though shorter, allow most races to be completed in daylight. It is a month with a high density of events across the territory: from the beech forests of the north to the Mediterranean sierras. October marks the start of the rainy season in many areas, which can make terrain more slippery and technical. For many runners it is the month to close the season, the last big objective before the winter rest.
