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.
Forecast for 2 October

Anboto KB
Anboto KB is the vertical kilometre of the Duranguesado: it climbs from the Arrazola district (Atxondo, Bizkaia), at the foot of the north face, to the summit of Anboto (1,331 m), gaining around 1,092 metres of positive elevation in under 5 kilometres. It is organised by Asuntze Mendi Taldea and scores for the Basque Country Vertical Kilometre Cup.
A 5-kilometre course, all uphill
The race starts already steep on meadows and beech-wood paths, and from halfway it becomes a scramble over grass and limestone rock with ramps of more than 40%. The final section, on the ridge, forces you to use your hands. There is not a metre of flat or downhill: it is continuous effort, almost breathless, from 30 minutes for the best to an hour and a half for the rest.
The Saturday of the Anboto weekend
Anboto KB is held on the Saturday, and the next day Sorginen Lasterketa runs the same massif from Axpe. Many runners do both races as a themed weekend around the most myth-laden mountain in the Basque Country, home of the goddess Mari.
Atxondo beyond the race
Arrazola is a handful of farmhouses at the foot of an imposing wall; Axpe, a few kilometres away, is famous for its food, and the Urkiola pass with its sanctuary and beech wood rounds off the plan. See more races in the Basque Country and plan your weekend with the planner.
