On the map, the numbered circles indicate checkpoint locations. In the terrain, checkpoints are marked with an aluminium post, each about 1/2 metre high. Each post has a hittaut-decal, a checkpoint number and a letter code. Write down the letter code on each checkpoint you visit and register them online (see "Register checkpoints and win prizes" below).
There will be a total of 90 numbered checkpoints with colour codes explaining the navigational difficulty.
Green = easy. Accessible by wheels (bike, stroller, wheelchair)
Blue = easy to medium. Checkpoint might be located a bit further from the path.
Red = medium. Checkpoint is located further out in the terrain.
Black = hard. Checkpoint is located in the terrain. Challenging navigation.
