Advanced Route Choice

1
Advanced Route Choice

• Canadian Orienteering Federation 2004

2
Advanced Route Choice

• Aim off
• Climb early
• Contouring
• Attack Points (Traffic Light)
• Rough Compass and map reading (red lining)
• Simplify

3
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

4
Climb Early

• Advantage
• Better attack point options
• Less fatigued when attacking control
• Better visibility near the control
• Disadvantage
• Eliminates some route choice options

5
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

6
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
8
Attack From Above
9
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
