Gear recommendations
Bring a waterproof jacket (37% 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.
Sun protection essential (10h sunshine, up to 20°C)

The trail of the corsair city
The Trail de la Côte d’Émeraude is the coastal race of Saint-Malo, the walled city guarding the Rance estuary. The 54 km starts on Saturday and follows the coastal path through beaches, dunes and small harbours, with 1,200 m of climbing in boardwalks and short rises.
Sunday brings the 32 km, gentler and aimed at anyone wanting the distance without Saturday’s price. Both finish by the sea with the walled city as the backdrop.
A popular race
The organiser is Saint-Malo Sports Loisirs, with over 1,000 volunteers across the two days. The route passes the Pointe de la Varde, Rothéneuf and the Conchée fort, with views to the Chausey islands.
Preparation
This is a runnable trail with little climbing, but dune sand and Channel wind punish the quads. Train steady paces and get a session or two on sand. Mandatory kit is minimal: windproof, reusable cup and charged phone.
September in Brittany is mild but can rain. Sleeping inside the walls turns the weekend into a break. More Breton races at /en/races/francia/bretana/ and kit at /en/planner/.
