La Couteliere is a nature race held in Biesles, a village in Haute-Marne, northeastern France. Participants can choose from 15 km and 7.5 km trail races, plus a 2.5 km youth race. The Association des Parents d'Eleves de Biesles organizes the event, giving it a local community feel.
The 15 km race begins at the Biesles football ground. A notable feature is a steep 15% climb, adding difficulty beyond what the distances might imply. Runners have options for the longer nature course, the shorter 7.5 km route, or the youth race, welcoming both adults and younger participants.
