There are 30 CIRCUIT TOURS in the guide, which are marked with four colours. Each tour has a described SHORTCUT. We can use it to shorten the route and ride a HALF-ROUTE. Routes are connected by LINKS. Circular tours, shortcuts and links form a 1500 km long cycling network. On the network, five COMPOSED TOURS are described. According to your own desire, you can assemble your route along the described network and calculate the distance and altitude change.
