Please make sure you have either washed or sanitised your hands before going to your pre-start area. Note, hand sanitiser is not affective on dirty hands. There will be no key-drop facility at the event.   

There will be two pre-start areas: (A) for Blue and Yellow and (B) for Short Green and Green. See attached map for locations.

Only if it is no more than 5 minutes before your start time should you go to your pre-start. DO NOT gather around the pre-start areas! You may only join your pre-start lane when there is space available and the official calls your name when you can clear your dibber and join the queue. Hired pre-cleared dibbles can be collected from a box at the pre-start where there will also be a SIAC battery test control, loose control description sheets and a hand sanitiser. 

At each pre-start competitors must queue 2m apart, marked by tapes. When you are told to go to the start you should check your dibber and follow the tapes to your start box which is approximately 150m away, please do not linger on the marked route. NOTE, your start time will be the approximate time you leave the pre-start to go to the start box not the time you actual start your course. 

At each start box competitors should wait until the Start official allows you to start when you, including SIAC users, must punch the start control box for your course then pick up your map. You should then move away, if necessary stopping only briefly to read your map. 

Note, Yellow course maps will be available at the start box, not at the pre-start. Study time wil be allowed at the discretion of the Start official. Competitors must punch the Yellow course start control box before leaving the start area.

Explanation of colour courses

  • Orange progress to basic use of the compass and route choice. They are ideal for novice adults or experienced youngsters.
  • Light Green are ideal for improvers as the navigational difficulty begins to increase and uses simple contours and point features.
  • Green are used mostly by experienced under 18’s and adults wanting a short but challenging course with a very hard navigational difficulty.
  • Blue are a longer, more physically demanding course in comparison to the green. The distances are more varied between controls and the course attracts experienced orienteers.
  • Brown & Black are very physically demanding and have a very hard navigational difficulty. They are for experienced orienteers only.
