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

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.

Trail Trans Serra da Groba
Trail Trans Serra da Groba is the mountain race of Baiona (Pontevedra), at the southern tip of the Rías Baixas. It runs through the Serra da Groba, a low but genuinely wild coastal massif covered in gorse and Atlantic scrub that drops straight into the ocean. The long race is 29 kilometres with around 1,000 metres of positive elevation, and there is a 16.5-kilometre Trailiño for anyone looking for a first mountain experience.
A 29-kilometre course
The route climbs from sea level to the ridges of the range on forest tracks and paths through the gorse, with technical granite-rock sections and muddy patches in the hollows. There is no single big climb, but the terrain breaks your rhythm constantly and the Atlantic wind hits as soon as you gain height. The views over the Cíes islands, the Vigo estuary and the mouth of the Miño are the reward.
The wild horses of A Groba
The Serra da Groba holds one of the largest populations of wild horses in Galicia, the so-called garranos or bestas, which graze free all year and gather in herds managed by the local besteiros. You are very likely to meet several during the race. Watch them from a distance, without disturbing or feeding them.
Baiona beyond the race
Baiona was the first port in Europe to receive news of the discovery of America, when the caravel La Pinta arrived in March 1493. The old town, the Monterreal fortress (now a Parador) and the seafront promenade make for a perfect weekend trip. See more races in Galicia and plan your weekend with the planner.
