Trail le Hibou is a mid-January trail race held in Fismes, a town in France's Marne department, near Reims. The primary listed distance is 11.3 km, commonly referred to as a 10K, featuring a single loop with approximately 140 metres of elevation gain. This event is organized by US Fismes C.A. and is part of a larger series of race formats.
The course follows paths and trails connecting Fismes and Blanzy-les-Fismes, offering a semi-nature running experience rather than a typical road 10K. Participants begin and conclude at the boulangerie de Fimette, pass the birthplace of Albert Uderzo, co-creator of Asterix, in Fismes, and traverse the village of Blanzy-les-Fismes. The organizers describe the 11.3 km race as the distance designed to bring people together, and a past edition attracted over 300 runners.
