There is still the famous ordinance in force here in Slovenia, which regulates riding bikes in natural environment. Possible questionable parts of trails described are not extra indicated. Riding and using road books available on this website are at your own risk and responsibility. If in doubt, walk the questionable part.

How to use the Road Book? Follow important crossings (black in the Road Book) and ride on more bitten path and/or straight in the same direction between them. When in doubt, check the detailed part of the Road Book (not black).

Do not expect that kilometers on your bike computer will match the ones in the Road Book. And this is the case even if you have your bike computer correctly calibrated (How to calibrate a bike computer?). Deviation has to be taken into account. In the case of bigger errors, it is useful to measure shorter distances, i.e. from crossing to crossing. 

Maps have to be used in any case, preferably Slovenian national topographic maps (Drzavna topografska karta) in the scale 1:25000. They can be bought at local Geodetic Administration Offices (Geodetska uprava) in Slovenia and also in specialized bookstores (Kod&Kam). There is also on-line version of the complete scale set of Slovenian maps (Interactive atlas). You have to register to use it, otherwise it is free of charge.

About riding time: this is time given by a bike computer in auto stop mode, meaning that snack breaks and other stops are not included. But you can get rough total time if you take an hour for each 10 km.

in any case it is best to print by using Adobe Reader:

The way you measure the wheel's circumference is also very important. The best is that you ride your bike in a straight line along the street and count the turns of your wheels. Measure the distance traveled with a tape measure. Dividing the distance with the number of turns gives the circumference. It is wise to write down the tire pressure at the time you carried out this procedure. And of course it has to be repeated after every tire change.

But also if everybody had calibrated bike computers, it is very likely that there would still be deviations between bike computers. Why? Because of different line of driving, taking shortcuts through turns, etc.
