Montefortino, Rifugio Sibilla Vetice, Santuario dell'Ambro

Very demanding ride, climbs with significant and long gradients. The first is the classic climb to Sibilla, with an initial variant through Sossasso and Colleregnone; the second climb is divided into two: first a portage from the Tenna river to Tribio (upon reaching the houses, turn right and 50 mt on the cemented road with a powerful heart) and the second on a nice demanding gravel path up to Prati di Vetice. The first descent is in open terrain, it's better not to follow the track and stay lower, the second from Rubbiano to the Tenna river, very nice and fast (watch out on the steep straight, at the end there's a nice turn to the right), the third is the trail 225 that descends to Ambro, quite tough and demanding "trialistic".
