If in doubt for any procedure, follow established rules for Foot Orienteering. Definition of Trail Orienteering - Control Choice.
Competitors visit control points in a set sequence.
They interpret the map to choose which of a number of markers represents the one in the centre of a printed circle. This decision must be recorded. The competitor with the highest correct score is the winner. In the event of a tie, the competitor recording the shortest total time to make decisions at designated controls wins. The time of travel between the start and finish, within a defined maximum, is irrelevant to the competition result.
