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.

Uharte-Arakil Beriain Km Bertikala: Sakana’s Vertical Kilometer
The Km Bertikala is the vertical kilometer race connecting Uharte-Arakil with the summit of Beriain (San Donato), the most iconic peak in the Sakana valley in Navarra. Now in its 16th edition, it’s one of the most established vertical races on the Navarrese calendar, counting for both the Navarre Championship and the Euskal Herriko Kopa.
The 5 km course climbs 1,023 m of elevation gain, starting from the town square at 471 m and finishing at the chapel of San Donato at 1,494 m. A pure, grueling ascent that tests endurance and mental toughness.
The Course: From Oak Forest to Summit
The race starts from the Uharte-Arakil town square, passes through the Itxesi neighborhood to the swimming pool area, and enters a dense oak forest. The woodland gradually gives way to beech forest as altitude increases, before the final open sections leading to the summit.
Key course details:
- 5 km distance, 1,023 m D+
- Cutoff at Auntzaldapa (km 3.3): 50 minutes
- Maximum time: 1 hour 45 minutes
- Staggered pair start
- Finish at the San Donato chapel with panoramic views of all Sakana
Uharte-Arakil and the Sakana Valley
Uharte-Arakil is a small Navarrese municipality at the foot of the Aralar mountain range, in the heart of the Sakana valley. Well-connected by train and road, it’s a strategic base between Pamplona and the Basque Country.
The summit of Beriain (1,494 m) is the highest point of the Andia/Urbasa range visible from across the valley. At the top stands the San Donato chapel, a traditional pilgrimage site. On clear days, the views from the summit span from the Pyrenees to the Cantabrian coast.
