Ultra Trail des Monts d'Arrée 2026

If you want a trail that smells of forest and real Brittany, the Ultra Trail des Monts d’Arrée in Commana will speak to you 🌲.

Here, you run in the heart of Finistère, where the Monts d’Arrée have that slightly wild feel that makes you forget everything else 🏔️.

Want a format that suits you: 13 km to treat yourself, 22 km to play with the hills, 42 km to tell yourself a real story, or 65 km to go looking “a little farther” than planned. 🥾

The terrain, I’ll sum it up like your local guide: winding trails, undergrowth that breathes, and that Monts d’Arrée vibe that makes you feel like you’ve set off on a micro-adventure without leaving Commana 🌿.

And after the effort, don’t rush off right away: go get some air (again) at Lake Drennec, take a detour to the Relec Abbey in Plounéour-Ménez, climb up to Roc’h Trévezel for the view, or go get intentionally lost along the ridges of the Monts d’Arrée 🗺️.

You’ll see: here, you don’t just “do” a race—you make yourself a memory… and in the Monts d’Arrée, memories have character.
