Couses natures de Niederbronn - Niederbronn-les-Bains 2027

Couses natures de Niederbronn is a trail-running and hiking series held in Niederbronn-les-Bains, Bas-Rhin, eastern France. The event utilizes Vosges terrain, offering five routes: a 63 km trail with 2,350 m elevation gain, a 43 km trail with 1,700 m, a 27 km trail with 1,100 m, a 13 km discovery trail with 420 m, and a 12 km walking route. The longest race, La Trace des Brigands, begins before dawn. The other races start throughout the morning, from the 43 km Grand défi des Vosges to the shorter Vosgi'gazelle, Vosgi'balade, and Mac VI routes. Les vosgirunners organize the event. This format accommodates diverse participants on the same day: long-distance trail runners, individuals opting for a shorter mountain run, and walkers who wish to explore the Niederbronn paths without competing in the longer races.
