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.

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.

The race
The Gran Trail Sobrarbe was born in Aínsa, created by the Club Atlético Sobrarbe, and is now one of the most complete spring events in the Aragonese Pyrenees. With close to 1,200 entrants in 2025, it offers four main routes for every level, from the 14 km ZTrails Cruz Cubierta to the 69 km flagship.
The route
Start and finish are in Aínsa, a medieval town overlooking the meeting of the Cinca and Ara rivers. The courses follow trails, tracks and passes through Sobrarbe and link villages such as El Pueyo de Araguás, Tella-Sin, Laspuña, Puértolas, Labuerda and Boltaña. The 69K has 3,043 m of climbing and the 44 km marathon 2,090 m. Trail Zona Zero Pirineos (25 km, 980 m) is the ideal entry point for mountain running, and the 14 km ZTrails (510 m) is perfect for a first race.
When to go and what to expect
In late April the Pyrenees mix sun, mud and wind at altitude. You often start cold and finish in short sleeves, so carry a light windproof layer and a cap.
How to prepare
The organisation publishes the tracks before the race and offers a 15-week training plan. Recce the technical sections and train the descents, which punish the quads.
