Gear recommendations
Bring a waterproof jacket (33% 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 8°C)

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.

Ecomaratón de Montaña La Donaira: what to expect
Ecomaratón de Montaña La Donaira brings mountain runners to El Gastor (Cádiz) on November 21, 2026. The organiser, La Donaira (con el Ayuntamiento de El Gastor), offers 2 routes (Trail 25K / Trail 15K) for people who enjoy trails and the atmosphere of a grassroots race. It donates 10% of entry fees to environmental causes and adds a 12 km hike, a kids’ race and a play area; the 500-place cap is already full.
Route and elevation
- Trail 25K: 25 km with 1250 m of climbing.
- Trail 15K: 15 km with 700 m of climbing.
Expect a mix of trail, track and the odd technical descent. If it is your first time at this distance, start steady and save energy for the second half.
How to prepare
Combine weekend long runs with hill repeats. In the last six weeks, accumulate climbing similar to race day and practise descending, where most legs are lost. At this time of year also train in the cold and with a headlamp in case of an early start.
Gear and logistics
Shoes with medium lugs, a light pack with two bottles or soft flasks, gels and a warm layer are the basics. The Pack 360 on this page brings together gear, nutrition, accommodation and transport. Find more nearby events in the regional race list and plan your season with the planner.
