The Argentréenne 2026

The Argentréenne is the meet-up where you come for fresh air, forest-scented trails, and that little thrill that switches you into adventure mode right from the start 🌲.

Here, in Argentré (Mayenne), you run as close as possible to nature: wooded paths, playful trails, sections that get you going again, and the kind of village atmosphere we love—simple and warm. Because in Pays de la Loire, we know how to welcome you… and make you scramble along with a smile 😊.

As for formats, you choose your story: 5 km to treat yourself without overcomplicating things, 10 km if you want an accessible challenge (and there are two of them, so you can find your style), 17 km to enjoy yourself for longer, or 25 km for those who like it to last and leave you with memories all over your shoes 👟.

And after the effort, keep the fun going just a stone’s throw from the start: a relaxed stroll around Argentré, a trip to Laval to wander through Old Laval and see the Château de Laval, a break along the Mayenne on the towpath, or a getaway to nearby Vitré for its medieval town center just around the corner! 🏰
