Les défis de la Comté is a four-stage amateur running challenge in the Haut-Doubs, with Pontarlier serving as the closing stop. The series is only three years old, offering local runners a way to move through this part of eastern France.
The other stages are Malbuisson, Levier, and Sombacour before the final leg in Pontarlier. The Pontarlier stage is new this year, going through the town center for the first time, with Commerce Pontarlier Centre helping organize it and runners invited to show up in costume.
