Asics
Asics Gel-Trabuco 14 GTX
A best-selling beginner trail shoe: GEL cushioning, good stability and a waterproof GORE-TEX membrane. Versatile and reliable for training on mixed terrain in any weather.

Berghaus
Berghaus Paclite 2.0 GTX
Waterproof jacket with a Gore-Tex Paclite membrane (around 330 g). Fully waterproof with taped seams, fixed adjustable hood, storm flap behind the zip and cuff adjustment. Packs down small in a vest. Heavier than a pure running hardshell, but it meets the waterproof-breathable membrane requirement in race rules and is the affordable route into Gore-Tex.

Brooks
Brooks Cascadia 20 GTX
The Cascadia 20 with a GORE-TEX membrane: stability and protection for rocky mountain terrain, keeping the foot dry on cold, rainy days.

Gore Wear
Gore Wear C5 GORE-TEX Glove
Glove with a fully waterproof, windproof GORE-TEX membrane and light insulation. The pick for running in snow, sleet or heavy rain while keeping your hand dry.

Gore Wear
Gore Wear M GORE-TEX Thermo Glove
Warmer variant of the Gore Wear C5 GORE-TEX: the same fully waterproof, windproof membrane, with extra thermal lining for intense cold on top of snow or rain. The pick when the problem isn't just water, but water AND hard cold at once.

Chubasquero Gore-Tex Shakedry ultraligero (110 g). Impermeabilidad total sin membrana interior, altamente transpirable. El referente para corredores de montaña.

Lightweight waterproof glove built for running, not just standing still in the snow: a waterproof membrane with more dexterity and less bulk than a thick membrane glove, for sustained rain without giving up handling gels or poles.

Salomon
Salomon Bonatti WP
Chaqueta cortavientos impermeable ultraligera (135 g). Costuras selladas, capucha ajustable y ventilación trasera. Se pliega en su propio bolsillo.

Salomon
Salomon Speedcross 6 GTX
The Speedcross 6 with a GORE-TEX membrane: the same aggressive 5 mm lugs for mud and soft ground, now waterproof for winter, rain and snow.

Sealskinz
Sealskinz Waterproof Lightweight Glove
Lightweight waterproof glove from a brand that specializes in outdoor sport waterproofing. A solid middle ground between a thin windproof glove and a thick membrane glove: genuinely waterproof without the bulk or price of the Gore C5.

TRIWONDER
TRIWONDER Polainas Impermeables Trail
Waterproof, breathable low gaiters for trail running, hiking and mountain use. Under-shoe strap and adjustable elastic band. A budget-friendly alternative to premium technical brand gaiters.

Trail La Grajera
Trail La Grajera is a mountain race through the forests and passes of the Campoo region in southern Cantabria, starting and finishing in the small village of Lantueno (Santiurde de Reinosa). Organized by Club Deportivo Elemental La Grajera with the help of sponsors and village volunteers, the race has become a reference event for trail runners looking for mountain terrain off Cantabria’s better-known coastal routes.
A 21 km route through the heart of Campoo
The long course covers 21 km with 1,400 meters of elevation gain (2,800 m accumulated), running through beech and oak forest along the ravines of Santiurde and Valleja Negra, with steep sections that test runners with mountain experience. The organization sets a time limit of 5 hours 30 minutes and reserves the right to apply cut-off points along the course.
The hikers route, open to everyone
Runners looking for a more accessible challenge can choose the 13 km route with 500 m D+, designed for hikers: there’s no age-category classification or podium, so each participant can take it at their own pace. It’s the perfect entry point for exploring Campoo on foot without the pressure of a stopwatch.
Campoo, beyond the race
Lantueno sits within the Campoo-Los Valles region, one of the areas in Cantabria most reliant on rural tourism. A few minutes away are Reinosa, the region’s main town, the source of the Ebro river and the Ebro reservoir, as well as the Alto Campoo mountain resort. Make the most of race weekend to explore this green, less-traveled inland Cantabria. Check out more races in Cantabria and plan your calendar with the season planner.
