Stone Challenge 2026

The Stone Challenge is your nature meetup in Herbignac, in Loire-Atlantique, where the forest whispers “come on, come along” and you answer “I’m coming” 🌲.

Here, no need to be a stopwatch hero: you choose your adventure, 7 km to treat yourself or 16 km to go a little further to find the best sections—always between undergrowth and big gulps of fresh air 🪨.

And if you come as a family, it’s even better: there are also kids’ races, so everyone gets their dose of play, pride, and shoes full of memories 👟.

After the effort, stick around: go for a stroll at the Château de Ranrouët, perfect for a walk and a couple of striking photos, then head to La Brière for a peaceful walk, and if you want to finish in “wow” mode, push on to Pénestin or La Roche-Bernard for a break by the water and a sunset that rewards it all 🌅.
