Endurathlon 2026

Endurathlon is your nature rendezvous in Saint-Denis-de-Gastines, in Mayenne, with a playground between forest and an adventurous spirit, Pays de la Loire style 🌿.

The concept is simple and terribly addictive: a 8.7 km loop and 24 hours to do as many as possible, at your own pace, managing your peak moments, your breaks, and your restarts ⏱️.

What I love here is the night-time atmosphere: when the light fades, the forest changes face and you experience a real timeless interlude, without taking yourself too seriously but giving it your all. 🌙.

You’ll love the “challenge + friends” mix: you get motivated at each pass, you run into people, you set off again, and you find yourself saying “come on, one more lap” (yes, it’s a bit like a ride… except you’re the engine) ! 🔥

And after the effort, to enjoy nearby: take a detour to Fougères and its impressive castle, head to Lassay-les-Châteaux for a postcard-perfect stroll, or go to Mayenne along the river for a gentle walk and a well-deserved terrace! 🏰
