Safety
Considerations
All participants should:

|
have a compass and know a
safety bearing. A safety bearing is a compass direction that will bring them
out to a major feature such as a road.
|

|
have a whistle
|

|
report back to the finish
before leaving for home.

Making
Route Choices
Factors to keep in mind when making
route choices:

|
7.6 meters of climb is
equivalent in energy usage to 100 meters of distance on flat land.
|

|
a person can
run ¼ mile:
- on a trail in 2 minutes
- in a field in 3 minutes
- in open woods in 6 minutes
- in thick vegetation in 10 minutes

Control
Placement
Control sites must be precise locations
that are found on the ground and clearly indicated on the map. Generally, if
controls are within 50 meters of each other, they must be on different types of
features to avoid confusion of the participants. Starts points must be at
precise locations just like controls. It is common to use streamers to guide
participants from the last control to the actual finish line.
Places where control sites are commonly located:

|
Point features
(small, distinct objects) such as boulders, knolls,
pits, depressions, rootstocks (root systems of uprooted trees), wells, cairns
(rock piles), individual trees.
|

|
Corners of larger features:
buildings, lakes, fields, swamps, paved areas,
building ruins.
|

|
Junctions
of 2 or more similar or dissimilar features such as trails, streams, fences,
roads, stonewalls, and power lines.
|

|
Bends in a feature
such as trails, streams, fences, roads, stonewalls, and
power lines.
|

|
Top or bottom ("foot") of
features such as cliffs, earth
banks, and small knolls.
|

|
Distinct land forms
such as reentrants, ditches, and spurs.
|

Course Printing
When hand-drawn, control points and
start and finish locations are best drawn with a fine-point red or purple pen.
Staedtler Lumocolor (permanent type) pens are great since you can see the map
features though the ink. For higher-level competitions, courses are pre-printed
using a special device, or placed on the map during the original printing.
Start location:
A triangle with 6mm legs is used to indicate the start point. The start point
should be in the exact center of the triangle. One of the points of the
triangle must point toward the first control.
Control locations:
Red or purple 6 mm diameter circles are drawn around each control feature/site.
The location of the control feature should be in the exact center of the
circle. For example, if the control site is a building, the center of the
circle should be at the corner of the building where the control flag is
located. Circles should be broken if they will cover up a feature. The
control number
is written on the map just outside the control circle. The top of the number
should point to north on the map. This allows the competitor to know which way
is north on the map without unfolding the map.
Finish location:
The finish location is drawn on the map in one of two ways:
If it shares the
same location as the start:
|

|
If its location is
separate from the start:
|

|
Connecting lines:
Lines are used to connect control points if a participant is to take the
controls in numerical sequence (typical). For example, cross country and motala
courses are designed so participants must take controls in a specified order.
Score orienteering permits the participant to go to controls in any sequence.
Therefore, Score "O" controls do not have lines connecting the control points.
This line does not necessarily indicate the fastest route to the control site.
Lines are drawn on the map from the start triangle to the first control, then
from control to control. A line also connects the last control to the finish
location. Break the line if it covers up important navigational features.

Control
Description Cards
Control description cards provide information
about the control site and control marker (flag). For beginners, this is done
in plain English (or whatever prevailing language). For more experienced
orienteers, a set of internationally-recognized symbols are used so that a
common language is not required in order to compete fairly against each other
(see
international symbols on Heather Williams' site).
A beginner's control description card will have three
columns. Column 1 contains the Control Number, column 2 the Control Code, and
column 3 the description of the associated control feature (and details about
the placement of the control flag in relationship to the feature if required).
* M = meter. The standard in Orienteering is to use metric units.

Orienteering
Course Levels (US system)
White
(Beginner or map hiker):
- Average length of course: up to 3 km
- Average number of controls: up to 8
- Difficulty of control placement: easy, obvious locations along roads, paths
and other major linear features
- Orienteering skills necessary to complete course: basic map reading, ability
to take a safety bearing with a compass
- Approximate winning time: 30 minutes
Yellow
(Advanced Beginner):
- Average length of course: 2.5 to 3.5 km
- Average number of controls: up to 10
- Difficulty of control placement: near large map features, less obvious than
white course features
- Orienteering skills necessary to complete course: more precise map reading
and simple compass use
-Approximate winning time: 40 minutes
Orange
(Intermediate level):
- Average length of course: 4 to 5 km
- Average number of controls: up to 10
- Difficulty of control placement: varied difficulty, difficult controls are
introduced with large collecting features
- Orienteering skills necessary to complete course: good map reading, basic
pace counting, beginning rough and precision compass skills
- Approximate winning time: 50 minutes
Advanced level courses (Brown, Green, Red
and Blue) These are all elite- or expert-level courses . Controls are placed in
difficult locations on small features. There are often several route choices to
a control. Courses combine all orienteering skills.
Brown:
3.5 to 4.5 km; up to 10 controls; winning time 50 minutes
Green:
4 to 5 km; up to 12 controls; winning time 50 minutes
Red:
5 to 7 km; up to 15 controls; winning time 60 minutes
Blue:
3.5 to 4.5 km; up to 20 controls; winning time 60 to 80 minutes
