This route starts from the birthplace of El Cid (Vivar del Cid) up to Valencia, where he died. Crosses seven provinces (Burgos, Soria, Guadalajara, Zaragoza, Teruel, Castellon and Valencia) following the naming places in El Cantar de Mio Cid, so it has a very important cultural component.
It has a very good signaling with colored markers sealing, so it is very easy to navigate, although not more counting using GPS or maps, to make it easier crossing.
