Trail Races in August in Spain 2026
August continues with July's dynamic: intense heat in lowlands and ideal conditions in high mountains. It is a month when the Cantabrian coast (Asturias, Cantabria, Basque Country) gains prominence thanks to cooler temperatures and green mountains. The Pyrenees remain the epicentre of major summer events. August is also a popular month for races in tourist settings, combining competition with family holidays — a factor many runners appreciate. Terrain conditions are dry across most of the country, with compacted trails that favour fast paces.

Tips
If running in northern Spain, do not be complacent: fog and rain can appear even in August on the Cantabrian coast.
Carry salt tablets or electrolytes: in August the risk of hyponatraemia is real if you only drink water.
Make the most of cool hours for training: 7-10 AM and after 7 PM are the optimal windows.
