Rondje Fort de Guentrange en de Alzette

The ride

Roll out of Boulange and let the ride unfold: first past the fort of Ouvrage de Bréhain, then on to Ouvrage du Bois-du-Four. The route dips into the Am Bauch nature reserve and follows the Alzette river before climbing toward Fort de Guentrange. With 971 m of elevation gain over 90.4 km, the Fensch river carries you along the final stretch back to Boulange.
