Permanent (TRIM) Orienteering Courses

A permanent orienteering course, also known as a TRIM course, is one that has a post (or some other sort of permanent object) marking control locations instead of the standard “box kite” type markers used for one-day meets.

These TRIM courses are designed for either competition or as an excellent opportunity for individuals, families, and school, scout, civic and military groups to practice map reading and navigation skills.

CROC has several permanent courses in the Portland area.  They are free to use and open year round.  Simply print the .pdf files you need for each course from the links below, go to the location, and run the course.  Have fun!
