Les Colberyennes is a trail race held in Schirmeck, Bas-Rhin, France, utilizing the Bruche Valley for its courses. Taking place in late April, it offers participants three distances: 5 km, 14 km, and 29 km. The event focuses on forest paths and natural terrain, distinguishing it from road races, with even the shorter distances maintaining a trail running character.
The 29 km course is the primary attraction, drawing the largest number of participants and featuring approximately 1000 metres of elevation gain. This distance presents a significant mountain-style trail challenge. The 5 km and 14 km races cater to less experienced runners or those seeking a shorter run. The event is designed for both beginners and seasoned trail runners, aligning with its location in Schirmeck. The valley setting allows for courses that include woods, ascents, and a distinct immersion in the Grand Est landscape, without requiring an ultra-marathon format.
