Top 5 trail races in Spain to enjoy this summer (intermediate level)
Spain offers some of the most spectacular trail running terrain in Europe. During the summer months, the high mountains become accessible, the days are long, and the race calendar is packed with events that combine technical trails, altitude, and breathtaking scenery.
If you already have experience in trail running and feel comfortable with distances between 25K and 50K, these five races provide the perfect balance between challenge and enjoyment. They are demanding, but achievable for intermediate runners who train consistently and manage elevation well.
Below are five of the best summer trail races in Spain for intermediate level runners.
1. Canfranc Canfranc
Location: Canfranc, Aragón (Spanish Pyrenees)
When: July
Why it stands out: High mountain atmosphere and technical terrain
Canfranc Canfranc has grown into one of the most respected mountain races in Spain. While it includes ultra distances, it also offers mid-distance options that are ideal for intermediate runners looking to test themselves in true alpine terrain.
The race takes place in the Aragón Pyrenees, near the French border. Expect steep climbs, rocky ridgelines, and technical descents. However, the course is well-marked and professionally organized, making it accessible if you have solid mountain experience.
What makes Canfranc special is the authentic high-mountain environment. You run above 2,000 meters in sections, surrounded by dramatic peaks. If you want to experience real Pyrenean trail running without committing to an ultra, this race is an excellent choice.
Recommended for: Runners comfortable with technical terrain and significant elevation gain.
2. Gran Trail Aneto-Posets
Location: Benasque Valley, Aragón
When: July
Why it stands out: Iconic Pyrenean landscapes
The Gran Trail Aneto-Posets is a classic in the Spanish trail calendar. While the event is known for its ultra distances, it also offers shorter formats suitable for intermediate runners.
The race takes place in the Benasque Valley, home to the highest peaks in the Pyrenees, including Aneto. The scenery is extraordinary: glacial lakes, granite ridges, and wide alpine valleys.
Although some sections are technical, many parts of the course are runnable, which makes it ideal for runners transitioning from shorter mountain races to longer, more demanding events. You will need good climbing legs, but the terrain rewards rhythm and pacing strategy.
If you want a race that combines beauty, prestige, and a well-established organization, Aneto-Posets delivers.
Recommended for: Intermediate runners looking to step up in distance while enjoying iconic mountain scenery.
3. Desafío Somiedo
Location: Somiedo Natural Park, Asturias
When: July
Why it stands out: Wild landscapes and less crowded trails
Desafío Somiedo offers a different type of mountain experience. Located in northern Spain, in Asturias, the race runs through the Somiedo Natural Park, a UNESCO Biosphere Reserve.
Here, the terrain feels wilder and less commercial than in the Pyrenees. Expect green valleys, high pastures, and long climbs with panoramic views. The technical difficulty is moderate, but the elevation gain can still be demanding.
For intermediate runners, the mid-distance options provide a solid challenge without overwhelming exposure or extreme altitude. The atmosphere is welcoming, and the race retains a local, authentic character.
If you prefer lush landscapes over rocky alpine ridges, Somiedo is a fantastic summer option.
Recommended for: Runners who enjoy long climbs, natural scenery, and a quieter race environment.
4. Trail Valle de Tena
Location: Tena Valley, Aragón (Pyrenees)
When: Late August
Why it stands out: Technical Pyrenean trails with strong mountain identity

The terrain is classic Pyrenean: rocky paths, steep ascents, and exposed sections with dramatic views. You will likely encounter high-altitude segments and sustained climbs that require steady pacing.
This race rewards preparation. If you train on technical trails and feel confident on uneven terrain, Valle de Tena can be a deeply satisfying challenge.
Moreover, the race atmosphere is vibrant, and the organization is known for its professionalism.

Compared to some other Pyrenean races, the technical level varies depending on the chosen distance. Intermediate runners can find an option that is challenging but not extreme.
Running in Ordesa is a unique experience. The combination of vertical walls, waterfalls, and wide open spaces makes every kilometer memorable.
Recommended for: Runners who want a scenic yet demanding mountain race in a legendary national park.
How to choose the right summer trail race in Spain

Technical difficulty: Rocky terrain and steep descents require specific training.
Altitude exposure: Some Pyrenean races reach above 2,000 meters.
Heat management: Although mountain races are cooler than coastal ones, summer conditions can still be demanding.
If you train consistently, practice uphill hiking efficiency, and develop downhill control, these races are well within reach.
