Spring Trail Races 2026 — March, April & May

Spring is the golden season for trail running in Spain. From March to May, temperatures are perfect for mountain running: no extreme winter cold, no crushing summer heat. Trails turn green, rivers run strong, and snow still caps the highest peaks creating spectacular landscapes. It's also the period with the highest concentration of races, from classic mid-distance events in Catalonia and the Basque Country to the first ultras in Andalusia and the Canary Islands. If you can only run one season a year, make it this one. We've gathered all March, April, and May races with their complete Pack 360 so you can choose the one that fits your level and your schedule.
