Orienteering Exercise: Leg splitting - theoretical

Key information

Exercise Type:	Simplification, Route choice, Theoretical exercise, Route planning
Target Level:	Junior level, Intermediate level
Intensity:	Low
Preparation time:	Less than 5 minutes
OCAD Required:	No
Min participants:	1

Take a course with several long/half-long legs. For each leg, divide the leg into parts by identifying your attackpoints, i.e. the points on the leg which are your safe points where you need to be 100% sure about where you are. Mark these attackpoints on the map, and then continue with drawing your planned route for the leg. Repeat for all legs in the course.

Aim:	Get a good technique for mastering long legs by dividing it into shorter and easier segments. See how it is possible to simplify complex legs by splitting. Not splitting long legs into easier/shorter segments - and having full control at the attackpoints - is one of the main reasons for the really big mistakes which we want to avoid.
Variants:	Do this exercise before running through a course, and then running through it afterwards according to the plan. See also the Leg splitting exercise.
Aids:	None required.
Terrain:	Any terrain will do.
Preparations:
Tips:	Use features which are easy to spot from as far away as possible and uniquely identifiable in this particular terrain-type as attackpoints. I.e. a small knoll is usually not a good attackpoint - a larger lonely boulder or a path crossing may be a good attackpoint.
