Event overview
The Fall Backyard Burn at Hemlock Overlook is a trail running race held on Sunday, November 16, 2025, at Hemlock Overlook Park in Clifton, VA (13220 Yates Ford Road). The event offers two distance options:
- 5.2 miles (one lap)

The courses run along the banks of Bull Run and use a mix of hiking trails (including the Bull Run Occoquan Trail), old dirt roads, open fields, forested fire roads, twisty singletrack, stream crossings, and minimal pavement. Runners will encounter rocks, roots, and varied terrain. The 5.2 mile course lists about 600 feet of elevation gain; the 9.5 mile option lists about 1,200 feet.
The park is noted for wildlife sightings such as deer, beaver, turkey, osprey, and great blue heron. The course is described as spectator friendly with several areas designated for family and friends.
