Ultra Sée 2026

In Le Petit-Celland, the Ultra Sée offers you a challenge that’s as easy to understand as it is hard to let go of: one loop, one hour, and off you go again… until you decide you’re the boss 🌲.

The concept is brilliant because it puts you in a village rhythm: a start every hour, you run a 6.7 km loop through the woods, and you’re back at base camp with just enough time to catch your breath, have a laugh, grab a bite, and head out again ⏱️.

You can come solo for a one-on-one with the forest, as a duo to trade off the highs and lows, or as a trio to turn the whole thing into a team adventure. The goal: last 12 laps… and keep smiling!💪

And after the effort, stick around—it's well worth the detour. Go check out Mont-Saint-Michel, take a breath of fresh air in Avranches and its Jardin des Plantes, take a break at the Bay of Mont-Saint-Michel for the great light show, or head as far as Granville for the seaside vibe and a well-deserved terrace 🏰.
