A Rules for Foot Orienteering Events - Orienteering USA

A.20.2 Course/Class structures

structure.
A.20.2.2 The Long format will be included in the United States Individual Orienteering
Championships event.
A.20.2.3 The Classic format is the basis for the United States Two Day Classic
Orienteering Championships. Awards are based on two-day total time results.
A.20.3 Technical Rules
A.20.3.1 MAP: Scale 1: 15,000 is encouraged for M/F-21+ courses, but if not practical,
1:10,000 is acceptable. For all other classes, 1:10,000 is standard, with
Contours 5m or 2.5m, or other intervals if explicitly approved by Sanctioning
Committee. ISOM standards apply.
A.20.3.2 TERRAIN SELECTION: Long course terrain can vary by region, but should
contain some technical interest. Variety is always desirable. It is also desirable
to have either pleasant vegetation, or route choice possibilities around thick
vegetation. The terrain should not be excessively hilly, thick, or dangerous. It
should be large enough to accommodate a suitable M-21+ course, but also
must contain a section suitable for beginner courses.
A.20.3.3 COURSE TYPE: A Long format course will be a point to point course.
A.20.3.4 COURSE PLANNING: Long courses should provide as many challenges, and
variety as the terrain allows. Route choice and long legs should be featured, as
well as changing conditions and leg lengths. Technical difficulty should be
generally high, but easier sections can contribute to change of pace.
