Ultra-Trails in the Canton of Jura

The ultra-trail in the canton of Jura is experienced on terrain made for endurance: deep forests, wooded pastures and ridges that follow one another without ever crushing the runner 🌲. The Franches-Montagnes plateau offers hours of smooth, runnable trails, ideal for working on your pace over long durations. Further west, the gorges of the Doubs add technical sections and descents that test the quadriceps. All of it can be prepared for without long journeys, from any village in the canton.

To aim for 80 km and more, preparation is all about consistency: long weekend runs, nutrition tested in real conditions, alternating fast walking and running on the climbs 🥾. The Jura lends itself well to this learning process, with few people on the paths and frequent water points thanks to farms and village fountains. The cool nights of spring and autumn also get you used to managing the cold.

The Les Courses du Mont-Terrible is the canton's long-distance gathering: on April 11, 2027, it starts from Porrentruy with a course that climbs up to 106 km in the heart of the massif ⛰️. The shorter formats, starting at 5 km, let you test yourself before taking the step up to ultra. The ultra-trails in the canton of Neuchâtel, very close by, extend the season.

After the race, Saint-Ursanne and its collegiate church invite you to stroll through a medieval setting 🏰. The canton of Jura is also discovered at the table, with Ajoie sausage and Tête de Moine cheese, two specialties that restore your strength 🧀. Build your ultra step by step: a 20 km trail, then a 40 km, then the long distance. The calendar of ultra-trails in the canton will guide you through this progression, season after season, all the way to the finish line.
