Fountainhead Course Description

The Fountainhead Half Marathon+ and 10K++ (actually 11ish K – about 7 miles) courses are absolutely tough and they are absolutely beautiful. Fountainhead Regional Park, in Fairfax County, VA, is only 30 minutes outside of Washington D.C. and has an extremely remote feel for being so close to a major metropolitan area. The half marathon(+) course includes a 6-mile long stretch of the Bull-Run Occoquan Trail (BROT) from Fountainhead to Bull Run Marina as well as three seldom used side trails along the BROT. The 10K(++) course uses a shorter section of the BROT and one of the side trails…yes…it’s the one with the really epic climb!

There are 4 aid stations on the 10K++ course and 7 aid stations on the half marathon course. All aid stations have water and Gatorade. The aid station at about mile 7 on the half marathon course has snacks and and a portajohn.

This race first and foremost open to all runners. In addition, it also serves as the Collegiate Running Association’s (CRA) US Trail Running Championship.
