Ultra Trail La Mayenne 2026

If you love trails that smell like forest, riverbanks that make you slow down just to look, and vibes where everyone pumps each other up without taking themselves too seriously, Ultra Trail La Mayenne in Daon is exactly your playground 🌲.

The big format is 85 km to take you across Mayenne in postcard mode: nature everywhere, shaded sections, and that feeling of “I’m far… but I’m good” 🧭.

And if you’d rather share the adventure, you can also experience it as a duo / team: less “solo in your head,” more “we’re in this together,” with memories that stick around for a long time 👫.

After you finish, stick around: take a break at the Port of Daon to catch your breath by the water 🚤, head over to Château-Gontier-sur-Mayenne for a stroll around town, and if you want to extend it in family or couple mode, go for a walk along the towpath or take a trip over to Laval to change the vibe without going far.
