Gear recommendations
Bring a waterproof jacket (57% 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
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.
Bring thermal layers (low of 7°C)
Buff
Buff Thermonet
Thermal tubular Buff with Primaloft technology. Traps body heat, ultralight and versatile: hat, neck gaiter, headband. Ideal for high mountain.
Craft

Thermal top with a windproof ripstop panel on the chest and a highly ventilated soft jersey back. Built for high-intensity sessions in cold, windy conditions, with long cuffs and thumb loops.
HANKER
HANKER Thermal Neck Gaiter
Unisex thermal seamless neck gaiter in Soft Air Plus fabric (97% polyester). Seamless fit designed for trail running, cycling, motorcycling and outdoor sports. A budget alternative to Buff for moderate cold.
Icebreaker

Long-sleeve thermal base layer made from recycled fabric with anti-odour treatment. Active thermal regulation, ideal as a base layer in the mountains.
Odlo
Odlo I-Thermic Women's Longsleeve
Women's long-sleeve thermal top with insulating panels placed over cold-sensitive areas (lower back and kidneys). A mid-layer built for genuinely cold winter conditions, mountain outings or cross-country-style trail sessions.
ROCKBROS
ROCKBROS Thermal Windproof Balaclava
Thermal windproof balaclava covering head, ears, cheeks and neck. Designed for cycling and motorcycling, it works just as well on windy, freezing trail runs.
