The 2018 Nav-X Challenge's season opener brings us back to a Wilderness a mere 40 minutes from downtown San Francisco (70 min from Sacramento). Briones Regional Park is a vast wild area with oak studded green hills, tucked in between Martinez and Lafayette, West of Walnut Creek. Using a quality map specifically designed for navigation sports, course setter Heidi Cusworth will be treating us to a Map Adventure sure to please any navigation sports enthusiast, whether you are looking for a scenic 2 hr hike in the green hills, or a 4 hr endurance race against some of the best in the West.

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
With its rolling, grassy hills and secluded, shady canyons, Briones is a secret wilderness surrounded by the towns of central Contra Costa County. Although the park is close to Lafayette, Walnut Creek, Pleasant Hill, Concord, and Martinez, there are peaks within it from which you can see only park and watershed lands for miles in every direction.
From Briones Peak, the highest point in the park, there are panoramic views of Mount Diablo and the Diablo Valley to the east, the Sacramento River and Delta to the north, the East Bay hills and Mt. Tamalpais to the west, and Las Trampas Regional Wilderness to the south.
About the Map
The map we will be using for this Map Trek is a high quality Orienteering map produced by the Bay Area Orienteering Club. It is scale 1:15,000, meaning that 1 cm on the map is 150 m in the terrain. The contour interval (elevation between two contour lines) is 7.5 m (~24 ft).
