O'xyrace trail blanc jurassien - Les Rousses 2027

The O'Xyrace Trail Blanc Jurassien is a winter night trail race on snow held in Les Rousses, within the Haut-Jura regional natural park. Centered around Lamoura and Prémanon, its race village is at the Espace des Mondes Polaires, placing the event firmly in Nordic ski territory, unlike a city road race. Participants can select from short discovery distances up to approximately 16 km. These routes feature moderate climbs made more challenging by snow, cold, and darkness. A 6.5 km hike and a Trail Blanc KID race for 12- to 15-year-olds are also offered, making the event suitable for families and regular trail runners alike. The primary courses consist of a single loop on marked, secured, and groomed tracks, incorporating sections of snowshoe paths and powder snow. The children's course is a straightforward out-and-back on a groomed track. Annually, the race attracts around 1,500 to 1,800 participants, including groups of friends, sports clubs, families, and those extending their stay for a mountain weekend. It is presented as the sole white trail in the Jura Mountains, with courses set within one of France's most extensive Nordic ski areas. The finish line offers a unique, festive element: runners cross onto a disco-themed ice rink. A prize perfectly suited to the region is also awarded: a 40 kg wheel of Comté cheese.
