How are courses measured?
Courses are measured as the crow flies, in a direct line from control to control. Unless you have wings, you will travel farther than this distance! Courses are measured in kilometers, so a good rule of thumb is to simply round up to miles to estimate how far you will go. So in a 5 kilometer race, you’ll likely travel up to 5 miles.

Green River College is an interesting mix of urban campus, sprint-style orienteering, and traditional forest/trail style orienteering. You will change between campus and forest multiple times on your course, so be prepared. Climb will be minimal; the forest sections can have some thorny undergrowth, so bare legs are not recommended.
The Varsity, Short Advanced, and Long Advanced courses are printed with half the course on one side of the map, half the course on the other side. Once you reach the end of the first half, just flip the map over and finish your course. The map exchange symbol on your control description sheet indicates where the map flip occurs.
The map has several less familiar symbols that you should be aware of:
Light gray attached to a building indicates an overhang. You can run underneath these!
Olive green in the campus area is a planted area that is out of bounds. Crossing these, even a single step, is grounds for disqualification. We need to maintain our access to this campus and trampling plants will cause us to not be allowed back. These should be fairly obvious even not looking at your map, but if you are unsure, go around.
Black X, as is usual for COC, denotes a man-made object. This is represented by an X on the control description sheet.
Black circle is a special symbol that denotes a light pole. There are a lot of these! This is represented by an O on the control description sheet.
Brown X, as usual for COC, denotes a rootstock – the roots of a fallen tree. This is represented by an X inside an O on the control description sheet.
Green O denotes a major stump. This is ALSO represented by an X inside an O on the control description sheet, as according to International Orienteering Federation standards.
Green X is a major isolated tree. These are mapped somewhat inconsistently; there are many more major trees than are mapped.
Green dot is a bush or small tree.
Blue circle, the symbol for well or enclosed spring, is used to denote fire hydrants. These are represented by the well symbol on the control description sheet; a circle with a wavy line underneath.
