Triathlon La Petite Trace in Marcel 2027

If you’re craving a real breath of fresh air in the Doubs, the Triathlon La Petite Trace in Marcel in Mouthe is holding the poles out to you: here, you glide right into the heart of nature, between forests and wide-open spaces, in the typical Haut-Jura vibe, Bourgogne-Franche-Comté style 🏔️.

You choose your track depending on your mood that day: 5 km to treat yourself without burning out, 6 km for the right balance, or 9 km to go after that little “Marcel, I want more” (promise, you’ll keep smiling)! 😄

And after the effort, stick around: take a detour to the Source of the Doubs, breathe deeply at the Remoray Lake Nature Reserve, or head to Chaux-Neuve to extend the fresh-air feeling—all just a stone’s throw from Mouthe 🧭.

If you’re coming as a duo or with family, you can also turn the day into a mini getaway: a little forest walk, a hot chocolate in the village, and a “red noses, warm hearts” photo session before hitting the road again (and then you’ll be able to say you really tracked it in the Doubs) ❄️.
