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.

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

The Jura ultra, between France and Switzerland
The Ultra Trail des Montagnes du Jura starts in Métabief and heads into the ridges of the massif, with sections that touch Swiss soil before returning to France. The flagship race adds up to 175 km and 7,000 m of climbing, gentle but relentless, almost all on forest track and fir-lined singletrack.
The race starts on Friday evening and finishes on Sunday: two nights of effort, with the hardest stretch on the descent towards base camp in the small hours of the second night. The 105 km and 75 km share much of the route, so the atmosphere is the same at every aid station.
A relay format too
Besides the individual races, the UTMJ offers a 300 km relay and a 175 km team event, a way into ultra running without going solo.
Weather and preparation
In early October the Jura brings fog, rain and 5 °C nights. Train with a headlamp, test your warm layers and plan nutrition hour by hour.
Métabief has resort hotels and apartments, and Pontarlier is 15 minutes away. More ultras at /en/races/francia/borgona-franco-condado/ and kit at /en/planner/.
