Cross-country routes should have large features that can serve as attack points. The distance should be 3 to 5 kilometers, with shorter distances in our steeper or more rugged parks. The advanced courses are designed for orienteers able to make full use of their maps, compasses, and the terrain. Legs should vary in length. Control sites should be on point featurs far from obvious relocation points.
Errors can result in large time losses for the longer courses.
