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

About This Activity

Returning for its ninth showing, this race has been the go-to event for hundreds of area trail runners looking for an awesome day of running in the woods. Held in one of the largest and most beautiful parks in the Washington DC metro area, these single-loop race courses have it all, from forested hiking trails, to wide fire roads, to stream-side single-track.


The 13.1 mile half marathon course includes 11.4 miles of twisty singletrack hiking trails, 1.1 miles of forested fire roads, and .6 miles of pavement at race start. The 10K course (6 miles actual distance) includes 4.3 miles of twisty singletrack hiking trails, .5 miles of forested fire roads, and 1.1 miles of pavement (with .6 miles of pavement at race start). Both courses offer miles of tranquil streamside trail running.
