A sporting adventure full of surprises! The route is very varied, alternating tracks, trails and places steeped in history. I enjoyed the descent in the Frau gorges which is very playful as well as the very beautiful tunnels of the old railway line. My favorite ♥️ was the medieval village of Mirepoix where I took a well-deserved break under the covers. And what views? The views of the Ariège Pyrenees were splendid!
