This is an interesting Apennine route with a considerable variety in scenery and all sorts of mountain roads. It is very challenging in terms of distance and altitude. It explores a considerable part of the pre-Apennine area around Fabriano, linking mediaeval castles, ancient hermitages and abbeys that still keep a charming and timeless atmosphere. The environment encountered is quite integral; here man has always interacted with nature in a balanced manner from time immemorial. The long climb at the start, the hard descent down Val di Castro and the last uphill from Sant’Urbano to Precicchie make it a route only for trained bikers.
