Trail races in Castile and Leon 2026

The continental climate imposes extreme conditions. Winters are harsh, with abundant snow in the ranges until May, while July and August bring stifling heat on the plateau and storms at high altitude. Spring and autumn offer the best windows: mild temperatures, accessible peaks, and landscapes in full transformation. Mornings can be freezing even in June, so always go prepared.

Castile and Leon is the region of the solitary, resilient trail runner. Here you don't seek glamour, but a direct encounter with raw mountain: glacial cirques, shepherds still using their old trails, stone villages where the bar closes at ten. The trail community is strong but discreet, with veterans who know every Gredos pass and young runners rediscovering forgotten ranges. Races have epic names—Backyard Haciendo Sed, Ultrail La Covatilla—and the philosophy is clear: the mountain rules, the runner adapts.
