Competition maps

The maps are normal Swedish orienteering maps to scale 1:15,000 with contour intervals of 5 m, in A4 size (30 x 21 cm). 
Colour code:

White   Forest
Yellow  Open land
Blue    Water
Black   Roads, paths, stones
        and buildings
Brown   Contour lines
Green   Tough vegetation,
        slow to run through

Clothing regulations

The Swedish regulations for orienteering races require clothing to cover the whole body except head and arms.

Starting procedure

At the start area you will be told where to put your receiver. This will be done one competitor country at a time.

As soon as all receivers have been handed in and the competitors are gathered in the waiting area, the time for the first start will be announced.

When your start number is called to start, you should check in at the gate. Proceed to find your receiver.

The map and your registration card will be given to you 10 minutes before the start.

You will be allowed to enter the starting area 5 minutes before the start.

The starting signal is given 1 minute before the first transmitter begins transmitting. When the start signal sounds, run through the marked starting corridor without switching on your receiver. There is one corridor for Seniors and Women and another corridor for Juniors and Oldtimers.

When you reach the end of the starting corridor, you may switch on your receiver and then proceed to find the hidden transmitters.

Transmitters

The transmitting schedule follows the IARU Region 1 ARDF Rules. Five hidden transmitters 1-5 are operating sequentially on the same frequency. 
Minute  Transmitter  Identification
        number       call (morse code)
1       1            MOE   -- --- .
2       2            MOI   -- --- ..
3       3            MOS   -- --- ...
4       4            MOH   -- --- ....
5       5            MO5   -- --- .....

A finish beacon with identification call "MO" is operating continuously on a different frequency. It is installed at the beginning of the finish corridor which has to be followed. The finish beacon has no punching device and is not to be visited.

Seniors should find all 5 transmitters.
Women should find transmitters 1, 2, 3 and 5 (no. 4 excluded).
Juniors should find transmitters 1, 2, 4 and 5 (no. 3 excluded).
Oldtimers should find transmitters 1, 2, 3, and 4 (no. 5 excluded).

Registration card punching

To prove that you have found each transmitter, punch your registration card with the red puncher located on a support near the transmitter. The registration card is water proof.

Time limit

The time limit is 140 minutes.

Finishing

At the finish beacon, a marked corridor will lead you to the finishing line. This corridor must be followed.

After crossing the finishing line, you must hand over your map and registration card to the official responsible, and proceed forward.

The maps are returned to the team leader in the evening, at the information desk.
