The first event in the inaugural 2016 Nav-X Challenge Series brings us to a wilderness a mere 40 minutes from downtown San Francisco (70 minutes from Sacramento). Briones Regional Park is a vast wild area with oak-studded hills, tucked in between Martinez and Lafayette, west of Walnut Creek. (Click on the photo above to see what awaits you.

Using a high-quality map produced by the Bay Area Orienteering Club, course setters Bill and Heidi Cusworth will be treating us to a Map Trekking adventure sure to please any navigation sports enthusiast, whether you are looking for a scenic 2-hour hike in the green hills, or a 4-hour endurance race against some of the best in the West.
