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

The trails are categorised according to difficulty: 0 and 1 (blue) the easiest, 2 (red), 3 and above this (black), the most difficult. The colour 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.
