What do the colors of the MTB trails on the map mean?

The trails are categorized according to difficulty: 0 and 1 (blue) are the easiest, while 2 (red), 3 and higher (black) are the most difficult. The color coding is from the OpenStreetMap classification.

By default, specific map details are associated with the route profiles. However, you can freely combine the map details with the route profiles according to your wishes.
