Hemlock Overlook - Clifton, VA

13 Miles or 10K
Hit the trail and leave the road behind!

The Hemlock Half Marathon/10K Trail Running Race is back for round two. The inaugural race in 2016 was a massive hit and racers loved the beauty and challenge of this event. If your idea of fun includes running on dirt, over rocks, through creeks, along stream-side single-track, and up challenging hills, then this race is for you.

Hemlock Overlook, located along the banks of the historic Bull Run in Western Fairfax County in Northern Virginia, feels surprisingly remote for being so close to Washington D.C. Sightings of deer, beaver, turkey, osprey and great blue heron are not uncommon in this 425 acre park.

Who's RacingOur trail running races often sell out before race day. So, REGISTER EARLY to claim your spot on the starting line!
