MerGeo is producing two rogaining events (navigation races) in 2012:

Rock Creek Ramble Navigation Weekend and 10-Hour Race, April 7-8, South of Sprague, WA in open, basalt scablands terrain

Three15er 24-Hour, September 29-30, Naches, WA in rolling to hilly Eastside forest and open land. We are seeking North American Championships status for this event. Look for more details on this page in the early part of 2012.

Both events have shorter course options to accommodate all fitness levels. We hope you'll join us for one or both of these events!
