Trail races in Basque Country — October 2026
The Basque Country is the birthplace of Spanish skyrunning with the legendary Zegama-Aizkorri. Green mountains, technical trails and an Atlantic climate that challenges even the most prepared runners.
2 races scheduled
Climate in Basque Country: The Atlantic climate means frequent rain year-round, but also mountains that are always green and mild temperatures. There's no truly bad season for running, though November to February combines rain with short days. From May to September days are long and temperatures pleasant (15-25 °C), though rain can appear without warning. Running here always requires a waterproof jacket in your pack — but that mud and mist are part of the Basque character.
