Gear recommendations
Bring a waterproof jacket (63% chance of rain)

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

Ultralight Gore-Tex Shakedry waterproof jacket (110 g). Full waterproofing without an inner membrane, highly breathable. The benchmark for mountain runners.

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.

Aloñako Igoera
Aloñako Igoera is a mountain race starting from Oñati (Gipuzkoa) through the mountains of the Basque Country interior. With its motto Hell awaits you!, the 21st edition in 2026 confirms its reputation as one of the most demanding races in the Basque Country.
The course
22.6 kilometres with 1,868 metres of elevation gain. The km-to-elevation ratio is brutal: an average of over 80 metres of climbing per kilometre. The terrain is mostly technical with just 3 km of asphalt — the rest is mountain trails, grass and rock.
The start is at Plaza de los Fueros in Oñati at 9:30 in the morning. Runners face a course with 6 aid stations that takes them through the peaks surrounding the historic town of Oñati.
Oñati, a noble town
Oñati is a gem of inland Gipuzkoa. The Sancti Spiritus University (the first university in the Basque Country), the Arantzazu Sanctuary carved into rock, and a history stretching back centuries. The town combines cultural heritage with a first-class natural environment at the gates of Aizkorri-Aratz Natural Park.
Technical Basque terrain
The Aloñako Igoera terrain demands shoes with aggressive grip. The wet grass typical of the Basque climate, combined with rock sections and technical trail, makes footwear choice critical. Read our best trail running shoes guide for advice on choosing the right shoe for wet Basque terrain. The gradients are sustained and in some sections extremely steep, making this race a complete test of strength and technique.
