Advanced Route Choice
Aim
off
Climb early
Contouring
Attack Points (Traffic Light)
Rough Compass and map reading (red lining)
Simplify
Aim Off
Advantage
Know which side of a catching
feature
Increased running speed
Simplify the map reading
required
Disadvantage
Longer distance
Tends to promote carelessness
Climb Early
Advantage
Better
attack point
options
Less fatigued when
attacking control
Better visibility near the
control
Disadvantage
Eliminates
some route
choice options
Contouring
Advantage
Maintain height, energy
Use contour as a “handrail”
Disadvantage
Rarely a straight line
Easy to gain, lose height if not skilled
Steep slopes are very slow to traverse
(steepness and vegetation grows at odd
angles)
Tops of hills often open, easy running
General Rule: 10m climb = 100m flat
Attack Points
Traffic Light (Green Yellow Red)
Green = Rough O to catching features
Yellow = Rough/precision O to Attack Point
Red = Precision O from Attack Point
Attack from above
Attack cliffs (foot of) from below
Boulders often more visible from below
Reentrants can be visible from below
Extend the control
“Traffic Light”
Attack From Above
Attack From Below
Redlining
Straight line compass
Map read ahead
Prevent errors by
looking for possible
parallel errors
Useful in flatter, open
terrain with good
visibility
Simplify
• Break it down
• Look for catching features
• Orienteer to the next catching
feature to shorten the leg
• “Long legs are just a series of short
legs”
