ENG : "This bold crossing in the heart of the Morvan Regional Natural Park connects the iconic Lake Settons to the historic town of Avallon. With its 55 kilometers and 1,100 meters of elevation gain, this route offers a demanding yet accessible profile for runners looking for a great mid-distance endurance challenge.

The course alternates between wild forest trails, rolling ridge paths, and more runnable sections typical of Morvan landscapes. It is a complete playground that requires as much effort management on the surges as concentration on sometimes technical trails.
