NEW TO MAP TREKKING OR ROGAINING?

Map Trekking is a “Navigation Sport” that has elements of a few other sports and activities like Trail Running, Fell Running (XC hill running), Hiking, Orienteering and Geo Caching.  More specifically, Map Trekking is a time-based challenge, 2 hrs or more in length, where participants try to score as many points as possible within the time allowed, by visiting checkpoints scattered across a vast, wild landscape.  Participants are free to decide which checkpoints to visit, and in what order.  Typically, a set time is allowed before the start for participants to study the map, and determine their route.  Participants travel on foot and navigate their chosen route using the map and a compass (No GPS allowed except for recording your track).  A late finish comes with point penalties, adding another layer of challenge to the sport.  Checkpoints vary in difficulty and the point value reflects the same, so that easy ones yield a lower point value than difficult ones.  To encourage beginners, course setters typically provide plenty of easy checkpoints near the start and finish location.

VENUE / PARK INFO

The camp, located in the hills just west of Fairfax, offers a taste of just about every type of terrain the Bay Area has to offer. From gentle, rolling grass-covered hills, to canyons filled with towering Redwood trees, and everything in between! The camp area in the center of the map is relatively flat, and will serve as the event center.  The area beyond the camp is more secluded and often hillier. Rock features are scarce, but can be good attack points.  You can expect to navigate through all types of vegetation, from open fields to all shades of "Green" (thicker vegetation).  The course may even take you by the remote site of a WWII aircraft that crashed on a hillside, supposedly carrying "top secret" material used in the atom bombs dropped on Hiroshima and Nagasaki. While most of the debris was carried off by military officials the night of the crash, and the remainder buried on site, one of the plane's engines washed down into a camp creek years ago, and is now on display near the ranger station.
