The Fountainhead Off-Road Half Marathon and 10K hit the EX2 race calendar for the first time in 2013 and it was an instant success! This fun and challenging course is a trail runners' dream and its location along the banks of the Occoquan Reservoir has some of the most beautiful and remote-feeling terrain in Fairfax County, VA, only 30 minutes outside of Washington D.C.

Event details and schedule

Both the half marathon and 10K are out and back courses that start with a short .5 mile road section at Fountainhead Regional Park before heading north along the Bull-Run Occoquan Trail (Blue Trail). The course extends to just past Wolf Run Shoals Rd. for the 10K and to Bull Run Marina for the Half Marathon. The northbound direction of the run features several fun single and double-track side trails and the southbound direction will be entirely on the Blue Trail, which parallels the Occoquan Reservoir. The location of the side trails and the flow of this race significantly limit two way traffic to just a few short sections. This brand new course design had never been used before its inaugural showing in 2013. Racers love the challenge, beauty, and fun of the course!
