Dirty Dozen Endurance Run 2026

The Dirty Dozen Endurance Run is Brazen Racing's timed race at Point Pinole Regional Shoreline in Richmond, California. Runners select 3 hours, 6 hours, or 12 hours and complete as many loops as desired. The main loop measures 3.37 miles, primarily on dirt fire trail, with approximately 150 feet of elevation gain per loop. A relay option is available for teams. The course returns runners to the start/finish area for refueling, gear changes, and interaction with friends or crew. During the final hour of each timed event, a shorter .42-mile loop becomes available for runners to add distance. The location offers wide bay views, with sightlines to seven counties and several bridges. Crews may establish personal aid stations, support staff are available on each loop, and the food service provides hot and cold options.
