LeDefi du Mont-Dol 2026

Looking for a race that makes you feel like you’re heading off on an adventure—without going far? LeDefi du Mont-Dol in Dol-de-Bretagne is a big breath of Breton air, between nature trails and beautiful heights—just enough to make you say “wow” and head home with your mind full of images! 🗺️

Two formats, two vibes: the 5.5 km to treat yourself and have a blast, and the 10.5 km to go find a little more “Mont” in Mont-Dol (promise, it climbs just enough to earn the view) ⛰️.

Here, you’re not running “against” the scenery—you’re running with it, between nature, elevation, and that little hint of sea air not far away, enough to turn every stride into a mini-journey 🌿.

And after the effort, keep the fun going just steps from the start: a stroll through the Saint-Samson Cathedral and the lanes of Dol-de-Bretagne, a detour to Mont-Dol for a view everyone can agree on, then head to the Dol Marsh for a quiet break… and if you want to extend the getaway, Saint-Malo isn’t far to finish with the ramparts and the sea in front of you 🌊.

You come to push yourself; you leave with a real breather: a challenge, landscapes, and a Brittany that makes you want to do it again (we don’t say “re-Mont,” but almost) 😄.
