On April 9, 2011, after 2 years of orienteering short courses locally with the Cascade Orienteering Club, we decided to up the ante!
The Rock Creek Ramble, put on my MerGeo, was our first "rogaine." A rogaine is a score-based orienteering event.
An hour before the start, participants/competitors receive a topographic map that is marked with checkpoints of varying point values. In that hour, you may plan your route to find as many checkpoints (controls) as you can or want to within the designated time limit. Ours was 4 hours. 3, 6, 8 and 12 hours are other common time limits. If you return to the finish past the deadline, the penalty is steep! Usually on the order of 10 points per minute late.
Rogaines are great, because you can walk or run- and get as many controls in any order as you please!
