Trail races in Basque Country — April 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.
1 race 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.

Tips for running in Basque Country in april
Always carry a lightweight waterproof windbreaker in your pack: spring storms arrive without warning.
April is a transition month: you may need short sleeves in the valley and long sleeves at the summit in the same race.
Springs and streams usually carry water in April: even so, do not drink from natural sources without filtering.
