Roll out of Terracina and follow the canal Fiume Portatore before the road opens onto Lago di Paola, a lake that keeps you company for a stretch. Further on you pass Castello Frangipane, a castle that marks the turn back toward town. The 73.2 km route is fully paved, with 148 m of climbing spread gently along the way, and it finishes right where it began in Terracina.
