BUFF® Epic Trail 105KM - 42KM - 21KM

Barruera, Vall de Boí 9th of July

BUFF® Epic Trail 105KM - 42KM - 21KM


BUFF® Epic Trail 21KM Barruera - Barruera

Aigüestortes and Lake Sant Maurici National Park is one of the fourteen national parks in the Spanish State, and the only one within Catalonia. Located at the heart of the Pyrenees, it constitutes -together with the parks of Ordesa and Monte Perdido and the one in the French Pyrenees- an excellent sample of the main ecosystems that we can discover in the Catalan high mountain areas.

Peaks of more than three thousand meters height; rivers, ravines, water falls and marshes which make us truly feel in the land of water; more than 200 mountain lakes varying in shape and color; and a great diversity of animal and vegetal species that struggle to survive in a harsh environment, all of which give life to this protected natural space, unique in the South of Europe.

The race starts in Barruera and climbs towards the village of Erill la Vall, with the first kilometer of the course running along a narrow trail that forces runners to fall into place before leading to a fast trail to Erill. With its extremely slight grade this section of the race can be run very quickly.

These first kilometers share the course with the Ultra race, but the half marathon continues along the Camí de l’Aigua along a shady path to the intersection with the Montanyeta valley, where the trail begins a fairly straight 500-meter climb with uneven terrain through the forest. At the end of this climb runners will find themselves at the top of valley and will enter high-mountain terrain at 2,000 meters above sea level, running along the Comaminyana valley to the peak of the same name, at 2,619 meters the highest point of the race with spectacular views of the Barrabés, Boí and Sant Nicolau valleys, and famous mountains like Bessiberris, which it feels like you can touch, Punta Alta and Aneto; and, of course, the summit of Roies de Cardet, site of the popular "Vertical Kilometer" race.

The course continues from the top of Comaminyana along an open ridge that boasts the same outstanding views, descending to Port de la Gelada (once again along the same course as the Ultra). The trail then continues downhill through high-mountain meadows and an open valley, passing by the Sant Salvador hermitage, and ends back in Barruera, where you pass through the village to reach the finish line.

Only two sections of the course are on asphalt: through the village of Erill and at the entrance to Barruera. The rest of the race is ALL run on trails and high-mountain areas, at times without any trails or paths.
