B2H Trail: the two great peaks of the Berrueza
B2H Trail — in Basque Berrotzako Bi Haundiak, “the two great peaks of the Berrueza” — is a mountain race held in Mirafuentes, a tiny village of barely fifty residents at the heart of the Berrueza comarca, in Tierra Estella (Navarre). It’s organized by Club Deportivo Mirafuentes Kirol Taldea, and its name honors the two summits that define the course: climbing “the two great ones” is the central challenge of the race.
A middle-mountain course with character
The race offers a single course of 17.4 km with about 1,000 m of elevation gain.
The route starts and finishes on Mirafuentes’ main street and crosses the Kostalera and La Plana areas, with steep pitches that test the legs in very few kilometers. It’s a middle-mountain race, without major technical sections, but demanding in concentrated elevation gain — the kind of race that rewards climbing strength over flat-ground speed.
A village race with soul
Unlike the major events on the Navarrese calendar, B2H Trail keeps the spirit of a race organized by and for the village: limited bibs, a close-knit atmosphere, and a course every neighbor in Mirafuentes knows by heart. It’s a good choice for runners seeking grassroots trail running, far from the crowds, deep in the Berrueza comarca.
Tierra Estella beyond the race
Mirafuentes sits just 15 km from Estella-Lizarra, the capital of Tierra Estella and a historic stop on the Camino de Santiago, with a medieval old town and a good range of accommodation and dining. The Berrueza comarca, dotted with small villages like Mendaza, Acedo, and Sansol, makes a great destination for combining the race with hiking routes and rural tourism. Check out more races in Navarre and plan your season with the planner.
