Gear recommendations
Bring a waterproof jacket (60% 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.

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.

The Walser trails of Monte Rosa
Monte Rosa Walserwaeg by UTMB follows the tracks of the Walser community in the Aosta Valley: 120 km and 8,200 m of climbing starting and finishing in Gressoney, from 15 to 18 July 2027. On total ascent it is Italy’s hardest UTMB World Series race after the Tor des Géants.
The programme reaches down so nobody is left out: 82 km with 6,300 m, 43 km with 3,100 m, 35 km with 1,800 m and 15 km with 650 m, plus a kids race. Each distance has its own start day, so the valley lives four days of party.
A course of glacier and high meadows
The route climbs from Gressoney’s 1,600 m to the passes facing Monte Rosa, with snowfields, scree and alpine meadows. The hardest section comes at night: temperatures up high drop to 3-5 °C even in July.
Preparation and logistics
July in the Aosta Valley is warm in the valley floor and cold up high: run in layers and change them fast. Mandatory kit is the UTMB standard and it is checked at bib collection.
Gressoney is 90 minutes from Turin and two hours from Milan; a car is almost essential. Book accommodation in January and keep Ayas Valley or Champoluc as fallbacks. More mountain races at /en/races/italia/valle-d-aosta/ and kit at /en/planner/.
