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.
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
Chubasquero Gore-Tex Shakedry ultraligero (110 g). Impermeabilidad total sin membrana interior, altamente transpirable. El referente para corredores de montaña.
Nike

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
Chaqueta cortavientos impermeable ultraligera (135 g). Costuras selladas, capucha ajustable y ventilación trasera. Se pliega en su propio bolsillo.
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.
TRIWONDER
TRIWONDER Polainas Impermeables Trail
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 (11h sunshine, up to 26°C)

Backyard Haciendo Sed Burgos
Backyard Haciendo Sed takes place every August in Sedano, a village in northern Burgos nestled in the Valle de Sedano. It’s a charity race with all proceeds going to Asociación Autismo Burgos.
The format
The third edition starts on August 29, 2026 at 9:00 with the classic backyard ultra format: a 6.706 km loop every hour, until only one runner remains. The race can extend into the following day if the competitive level allows.
Sedano and the valley
Sedano is surrounded by plateaus, limestone canyons and holm oak forests. The northern Burgos landscape is austere and beautiful — far from the usual tourist routes. The loop runs through this low mountain setting with around 150 metres of elevation gain per lap.
Charity
What sets Haciendo Sed apart is its charitable component. In addition to the backyard category, there’s a solidarity walk open to everyone from €5. Over €1,000 in prizes are distributed across individual, women’s and team categories.
August on the northern plateau
The thermal contrast is the big challenge: hot days exceeding 30°C and nights that can drop below 10°C. Managing clothing, nutrition and rest between loops is fundamental. Plan your fueling with our nutrition calculator for long endurance efforts.
