Dahlgren Heritage Rail Trail 50K

$90 6:30AM EDT Registration Opens October 1, 2025 at 6:24pm EDT

Course Description

 

The race is run entirely on the Dahlgren Railroad Heritage Trail which is a converted railroad bed and provides solid footing with little or no roots.  This trail is flat, smooth, and fast with a variety of surfaces ranging from dirt, gravel, grass, and pine needles.  
 
BACK BY POPULAR DEMAND - WE ARE STARTING ON THE EASTERN END AGAIN!!!  
 
The course is an out and back that starts at the eastern end of the trail and heads west from the start for ~6.5 miles before turning back.  The volunteers from Friends of the Dahlgren Rail Heritage Trail do an excellent job of ensuring that the trail is in peak shape for the race!

The trees along the trail ensure almost 100% shade during the run.

About the Trail

The 16 mile Dahlgren Railroad Heritage Trail follows the route of the old Dahlgren Branch rail line, stretching across King George County just south of the Potomac River in Virginia's Northern Neck. The trail is open for walking, running, cycling and other recreational non-motorized uses while preserving 240 acres of wildlife and natural beauty.
The Friends of the Dahlgren Railroad Heritage Trail is a 501(c)3 Nonprofit group that is volunteer-based and works to develop, preserve, and maintain this historic rail-to-trail greenway.
Please consider joining us in support of the Friends of the DHRT by donating to the trail HERE!

Cupless Racing from 2024 Onward!

We were grateful to partner with HydraPak in 2024 to bring you cupless racing! As an organization dedicated to maintaining a clean race and doing our part to keep our trails clean, starting in 2024 will be going cupless. This means we are eliminating the use of disposable cups at the 3H Half and DHRT 50K. Runners will have the option of carrying their own hydration vessels or using a HydraPak SpeedCup. Please bring your own SpeedCups. We will have a limited number available if you forget yours!
