EX2 Adventures: Fountainhead Off-Road Half Marathon and 10K

About This Activity

Due to overwhelming demand, the Fountainhead Off-Road Half Marathon and 10K hits the race calendar for the first time in 2013. This fun and challenging course is a trail runners' dream. 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. This inaugural race is going to be very popular.


Fountainhead Regional Park is situated along the banks of the Occoquan Reservoir in Western Fairfax County in Northern Virginia. The 10K and half marathon race courses are beautiful and consists mostly of hiking trails (including the Bull Run Occoquan Trail), horse trails, and old dirt roads. Competitors will run over rocks and roots, through several streams, and up some hills. This race is a new addition in 2013 and will surely be an instant hit!
