Berroeta Mendi Maratoi Erdia
The Berroeta Mendi Maratoi Erdia is a mountain race organized by Berroetako Mendi Elkartea in the Baztan Valley (Navarra, Spain). A growing event that reflects the rise of trail running in one of the greenest valleys of the Navarrese Pyrenees.
The courses
From the square in Berroeta, the courses head into the Baztan mountains:
- Mendi Maratoi Erdia (21.6K) — 1,274m elevation gain on the full course. Climb to the summit of Saioa through beech forests and mountain trails.
- 15K — 737m elevation gain on a shorter but equally demanding course.
- New Route (10K) — A new addition for this ninth edition, designed for those seeking a more accessible distance.
Terrain and difficulty
The Baztan mountains offer forests, meadows, and mountain trails typical of the Atlantic Pyrenees. Humidity is constant in this area, making good-grip footwear essential. The full 21.6K course with 1,274m elevation gain is a serious mountain challenge, while the 15K and 10K offer more accessible options. Check the recommended trail running shoes for wet terrain.
Saioa and the Baztan Valley
Saioa (1,418m) is the reference summit on the long course. The Baztan Valley, with its scattered farmhouses and ancient beech forests, is one of the most iconic landscapes of Navarra. Berroeta is one of the 15 villages that make up the municipality of Baztan. Discover more races in Navarra.
May weather in the Baztan
May in the Baztan Valley is wet and green. Temperatures range from 10-18°C, but rain is frequent and fog can appear at higher elevations. It is the rainiest area in Navarra, so a rain jacket is a must in your pack.
