Course and Class Structure

COURSES: Standard courses are color coded for easy reference, as listed below.
CLASSES: F = female, M = male. The number denotes age on Dec 31 of the year of the event. A dash ("-") indicates no age limit on that side. Example: M-12 is open to boys 12 and under, F35+ is open to women 35 and older. "Open course" classes and "21" classes have no age limit.
CLASS/COURSE ASSIGNMENTS: This table shows which classes are assigned to each course at sanctioned events; see rule A.11.2.8. Upper limits on the advanced courses do not preclude older orienteers running a longer course. (For example: an experienced 65-year-old, normally assigned to the Brown course, may run any of the longer courses of Green/Red/Blue and compete with the younger runners.) Alternatively, a competitor who's not ready for the difficulty level or longer distance assigned to his/her age group may enter any of the Open classes, those not designated with an age range.

*** Length is given for a typical "classic" or "long" course. Other courses will vary. See Rules (A.17 through A.23) for an explanation of the different race formats.

Caution: Select a course based on your experience level before choosing one for your age. Age classes are designed for orienteers experienced at that level.
