Haut'Marn Triathlon 2026

If you want a triathlon that smells like nature and lakes & ponds, the Haut'Marn Triathlon in Chaumont ticks all the right boxes—no fuss, and scenery with every push 🏞️.

Here, you come to enjoy yourself as much as to push your limits: you choose your format depending on how you feel, from the 10.3 km to get started, to the 103 km to live a real full-day story 💪.

The Haute-Marne terrain is the perfect mix: fresh air, water, green corners, and that “sporty holiday” feeling that makes you want to come back even before you’ve finished 🏊‍♂️.

And if you come as a tribe, it’s even better: the event also thinks about kids & juniors, perfect for turning the weekend into a little family adventure (and for creating ultra-motivated supporters)! 👨‍👩‍👧‍👦

After the race, I’ll guide you just a stone’s throw from the start: go gain some height at the Chaumont Viaduct, take a stroll in Parc des Silos to come back down gently, then head into the town center for a terrace break around the Saint-Jean-Baptiste Basilica and the old streets (Chaumont is as much to be savored as it is to be sweated through) 🍹.
