The 3 Mills Loop 2026

The 3 Mills Loop is the kind of meetup where you come to run… and you leave feeling like you’ve traveled, between nature, forest, and little stretches of “town to town” villages just the way we like them 🏞️.

Starting from Saint-Jean-sur-Reyssouze, in the Ain, I promise you a simple, genuine vibe: awesome volunteers, cheers that carry you, and a course that makes you forget the stopwatch so you can enjoy the scenery 🌳.

You choose your adventure: 4.5 km to have fun without burning out, 8 km, 12 km, 15 km or 18 km in “I’m savoring this” mode (in non-timed formats), or you go for 11.5 km, 16.5 km… and even 21 km if you want a truly full loop (promise, you won’t be running in circles) ! 🥇

And after the finish, keep the fun going just nearby: a little walk along the Reyssouze, a detour to Pont-de-Vaux for a break at the marina, a trip to Châtillon-sur-Chalaronne for its charming town center, or an escape to Bourg-en-Bresse to discover the Royal Monastery of Brou (and find yourself a well-deserved terrace) 🍽️.

If you come as a couple or with family, it’s even better: you run, they stroll, and everyone meets up again to debrief in a nice spot—the mills loop becomes a loop of good times ❤️.
