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.
Gore Wear
Gore Wear R7 GTX Shakedry
Ultralight Gore-Tex Shakedry waterproof jacket (110 g). Full waterproofing without an inner membrane, highly breathable. The benchmark for mountain runners.
Nike
Nike Pegasus Trail 5 GORE-TEX
The best-selling gateway trail shoe: comfortable, cushioned and versatile for moving from road to trail. Waterproof GORE-TEX version, perfect for beginners and easy runs on mixed terrain.
Salomon
Salomon Bonatti Pro Waterproof Glove
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
Ultralight waterproof windproof jacket (135 g). Taped seams, adjustable hood and back ventilation. Packs into its own pocket.
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.
Shokz
Shokz OpenRun
Open-ear bone conduction headphones with IP67 rating: they take rain, mud and a rinse under the tap. Up to 8 h of battery and quick charge (10 min for 1.5 h). The most rugged pick of the range for training in bad weather.
TRIWONDER
TRIWONDER Waterproof Trail Gaiters
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.
Sun protection essential (11h sunshine, up to 22°C)

Riaño Trail Run
The Riaño Trail Run is a multi-stage trail race held every June in the Riaño Mountains (León, Spain). Organised by TerraIncognita, the event offers three modalities: 3xTrail (84 km over 3 stages), 2xTrail (47.6 km over 2 stages) and Riaño Open (42.9 km single stage). The course traverses three distinct mountain ranges: Picos de Europa, Montaña Palentina and the Riaño and Mampodre Mountains.
The stages
- Stage 1 (Friday 25 June) — Oseja de Sajambre → Caín de Valdeón. 36.3 km. Start at 8:15 AM. Cutoff: 6:15 PM.
- Stage 2 (Saturday 26 June) — Valverde de la Sierra (loop). 21.5 km. Start at 9:00 AM. Cutoff: 3:00 PM.
- Stage 3 (Sunday 27 June) — Riaño. 26.2 km. Start at 8:30 AM. Cutoff: 2:30 PM.
The Riaño Open starts on Sunday from Lario at 7:00 AM, covering 42.9 km with 2,120m D+ and finishing in Riaño.
Three mountain ranges, one race
What makes the Riaño Trail Run unique is that it connects three mountain systems in a single event. The first stage crosses Picos de Europa on the Leonese side, linking Oseja de Sajambre with Caín de Valdeón along high mountain trails. The second stage explores the Montaña Palentina from Valverde de la Sierra. The third covers the Riaño and Mampodre Mountains, finishing in Riaño itself. Use our nutrition calculator to plan your fueling across three consecutive mountain days.
The reservoir and the village
Riaño is a village rebuilt above the waters of the Riaño Reservoir, inaugurated in 1987. The old village lies beneath the water, and the new one was built on the hillside overlooking the lake. The surrounding landscape is spectacular: limestone mountains rising vertically above turquoise waters, beech and oak forests, and wildlife including chamois, roe deer and golden eagles. It’s one of the wildest and least-known corners of the Cantabrian Mountains.
Stage race format
The Riaño Trail Run is a pure stage race: each day features an independent race with its own start and finish, and the overall classification adds up the times from all stages. The organisation arranges transfers between start and finish points, and offers Riaño Camp as a base camp for participants. The experience goes beyond competition: it’s a three-day mountain journey through the Leonese highlands.
