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
Chubasquero Gore-Tex Shakedry ultraligero (110 g). Impermeabilidad total sin membrana interior, altamente transpirable. El referente para corredores de montaña.
Nike

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
Chaqueta cortavientos impermeable ultraligera (135 g). Costuras selladas, capucha ajustable y ventilación trasera. Se pliega en su propio bolsillo.
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.
TRIWONDER
TRIWONDER Polainas Impermeables Trail
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.

Flysch Trail Zumaia
The Flysch Trail Zumaia is a coastal race held inside a protected area of the Basque Coast Geopark. Its paths skirt the cliffs of the famous flysch, a sequence of sedimentary rock layers that makes this stretch of Gipuzkoa one of the most spectacular geological landscapes in Europe. Starting and finishing at Plaza Eusebio Gurrutxaga, it gathers 650 runners at most.
Two routes through the flysch
The 24K adds 1,007 m of positive elevation and the 14K 487 m D+. They are leg-breaking courses, with constant ups and downs on coastal paths, tracks and technical sections, at low altitude but with a very demanding profile for the distance.
Autumn on the Basque coast
In early October the temperature is pleasant, but rain is a real possibility and rock and mud turn slippery. Lugged shoes, a light jacket and your own container to drink from (no cups at aid stations) are the base of a good race.
Zumaia beyond the race
Use the trip to visit Itzurun beach, the path to the San Telmo hermitage or neighbouring Getaria.
If you are combining your trip with other races nearby, take a look at the races in the Basque Country and plan your season with the planner.
Mandatory Gear
According to the official race regulations
Cupless race at aid stations: bring your own cup or container
