November 1, 2024,Boucle Serpent de l'Océan – Étang des Gatineaux au départ de Saint-Brevin-les-Pins

Excellent circuit 👍😍
The first half I regretted not having a gravel bike for the beautiful straight paths 😜 it's certain that I could have increased my average 😁
Nevertheless from Corsept for the second part.....fortunately I was riding a mountain bike 🤪 very technical part in the mud paths linked wouhaaaa !!!!
I put some explicit photos 😉😁

Good, varied gravel route.
Road, gravel paths, rutted trails, mountain bike trails, and sandy paths.
Ultimately, it was very challenging given my low average speed despite the fairly fast rolling sections.
