Control descriptions: Control descriptions will printed on the map. Loose description sheets will also be available during call-up, 2-3 minutes before your start. Runners are responsible for their own clue card holders or fasteners. Descriptions for white and yellow courses will be in both IOF symbols and English. Descriptions for orange course and above will be in IOF symbols only.
Control markers: Control markers will be IOF-standard orange and white flag. Many but *not all* markers will also include a blue stripe, either diagonal or vertical. Control markers will nearly always be hung at the feature using an existing/natural object rather than man-made stand or post. Every control will have a manual pin punch in the unlikely event of e-box failure.
E-boxes: All are Air enabled except for Start, into which all competitors must insert e-punch.
