Trail Races in March in Spain 2026

March marks the start of the trail running peak season in Spain. Temperatures begin to rise, days grow longer and the mountains come alive with the arrival of spring. It is one of the months with the most races on the calendar, especially in the southern half of the country where conditions are already spring-like. Courses are at their best: dry but not dusty trails, green vegetation, streams with water and temperatures that allow comfortable running without excessive heat or cold. Many runners plan their first major season objectives in March, capitalising on peak fitness after the winter preparation months.
