A route of 105 km full of hairpin bends and ascents to be overcome starting from the top of the Colle delle Cento Forche up to the Muraglione. From Castrocaro Terme follow the signs for Dovadola and Rocca San Casciano. Once in Rocca San Casciano, before the bridge turn left to Galeata and San Zeno. After a few hundred meters the road begins to climb for about 6 km to reach the summit of the Centoforche hill (m 551 s.l.m.). After the descent at the intersection with the SS 9 ter (Strada San Zeno), turn right to Premilcuore. Go through the village and continue on the state road. After 4 Km (after the Fiumicello junction) on the right there is a fountain. The road continues to climb for 10 km until you reach the Passo dei Tre Faggi where the descent begins to the SS 67. At the crossroads turn right where you face the last hairpin bends (Km 3) up to the Muraglione Pass. From here begins the sliding descent, crossing San Benedetto, Bocconi, Portico di Romagna, Rocca San Casciano and Dovadola back to Castrocaro Terme.
