Hi Brian. Check out http://vra.rogaine.asn.au/getting-started/what-is-rogaining.html
Essentially a rogaine is a team based event - 2 to 5 a team, but typically 2. The controls are in no set order. Each control is worth a certain number of points, some more than others. The value of points for each control is set by the setters of the course, and is a bit of an art form. It is expected that there be far more controls than is possible to visit within the allotted time, and there is heavy loss of points for even being a few minutes over time. Rogainers must make a decision as to what controls are possible to visit within the alloted time in order to maximize points.
Of course, no electronic navigational aids may be used such as GPS, altimeters, etc. Only a map and a compass.
