Once you have points planned, develop routes between them – one for each participant or team
– i.e. Route Yellow goes from the Start Point to Point 2, then to 7, 6, and 11. – The team going on Route Yellow (we’ll call them Team 1) gets the following directions:
➢ Directions for Route Yellow: ➢ Azimuth of 5° for 40m ➢ Azimuth of 230° for 100m ➢ Azimuth of 270° for 50m ➢ Azimuth of 115° for 70m ➢ Return to Start Point

ORIENTEERING
Agenda
Navigate to a series of points (controls) shown on a specialized topo map, choosing routes - on or off trail - that will help you find all the controls and get to the finish. Orienteering uses mostly terrain association to navigate from point to point.
What is Orienteering all about?

Who Goes Orienteering?
The orienteering course consists of a start, a series of control markers, and a finish. A participant is given a map, a control card, and a clue sheet. The control card is used to note the start and finish time, and to verify that the orienteer has visited each of the control markers on the course. The map is used to mark the start and finish locations, as well as the locations of each of the control markers.

confirms you are at the right
card to prove you visited the site
Success in orienteering requires a number of different skills. The winner of the competition is the participant who completes the course in the shortest time, so running ability is beneficial. The orienteer must be able to read the map, select an appropriate route from one control point to the next and successfully follow that route.
Map reading and analysis skills are by far the most crucial. A successful orienteer will develop the ability to observe the terrain around them, look at the map and identify where they are. They will develop the ability to determine the quickest route between points, as well as the navigational skills to traverse that route.
The clue sheet has clues describing the placement of each of the control markers - the type of geographical features at which the marker has been placed - and a “control code” which identifies the marker.

Orienteering Skills / Strategies
Skill: Visualize Terrain From the Map
Skill: Visualize Terrain From the Map
Skill: Recognize where you are on the map from the terrain
Use linear features as “handrails”. A handrail is any linear feature - like a trail, power line, stream, fence, or vegetation boundary - that you can “hang onto”
Handrails
At the beginning these handrails will probably be trails or roads that are very easy to follow. As you begin doing intermediate level courses, start looking for streams, ridges or vegetation boundaries.
Handrails
Following a handrail may make your route slightly longer, but the advantage is that you are much less likely to become disoriented
Handrails
Some Advanced Techniques
Aiming Off – if taking a bearing to a line feature, ‘aim off’ to one side or the

Often, on advanced courses, there are no true linear features to follow. In these instance, look for a series of features that more or less make a like in the direction you wish to travel. Break the route into several smaller

Does Orienteering Damage the Land?
– Not using pristine wilderness areas – Work with park rangers to avoid sensitive areas – Courses visit different controls – dispersed impact – Affected areas recover within weeks at worst – Low impact confirmed by scientific studies
What About Safety?
✓ ALWAYS REPORT TO THE FINISH whether you complete your course or not ✓ ALWAYS RETURN TO THE FINISH BEFORE THE ✓ COURSE CLOSING TIME whether you complete your course or not ✓ Carry a whistle ✓ Know your limits (physical and navigational) and stay within them ✓ Take precautions if allergic to poison oak, bee stings, etc.
