ERMINIG.CC
Creators of cycling adventures and ultra-distance events. [Erminig = Stoat/Ermine in Breton]
Erminig is the original organizer of the famous Gravel Tro Breizh, but it is also a laboratory for exceptional Road, Gravel, and MTB events dedicated to Ultra-distance, Long-distance, and Bikepacking.
Since 2018, our association has forged a rock-solid reputation by crafting the Gravel Tro Breizh: a magnificent—and grueling—off-road adventure across Brittany.
Today, driven more than ever by the passion to create, uncover secret tracks, and share intense human experiences with riders, we offer you an exclusive collection of events.
And take our word for it: the Stoat has designed and polished every single one of these new routes with the exact same care, high standards, and love for the terrain as the Gravel Tro Breizh!
Explore our upcoming challenges below and choose your next starting line. Adventure is waiting for you!
