Half Marathon
Information
Don't miss out on the opportunity to enjoy the beauty of the Dahlgren Railroad Heritage Trail. This is a scenic out and back course on a flat, smooth old railroad bed. Cash prizes, great competition, good food (including the opportunity to roast Krispy Kreme donuts over the campfire!), and awesome swag all make this a memorable event. And because we understand it can be a bit chilly in January ;) we will be starting the race at 9:00 am to let it warm up and let you get a little more sleep.
All finishers receive a custom race medal! The t-shirt deadline is January 1st. If you miss the deadline, you may still be able to get the size you'd like! We enter inventory into the website, so if you see your size available, you're good to go!
The time limit for the race is 3.5 hours - around 16 minute/mile pace.

Cupless Racing Starting in 2026!
We are excited to announce that we are including the Dahlgren Trail Half Marathon in cupless racing! Unnecessary waste and trash is something we are working to eliminate from our trail events. As an organization dedicated to maintaining a clean race and doing our part to keep our trails clean, starting in 2026 will be going cupless with this event. This means we are eliminating the use of disposable cups at the half marathon. Runners will have the option of carrying their own hydration vessels or using a HydraPak reusable SpeedCup provided at packet pick up. By going cupless, we are eliminating over 1,000 cups on race day, and are doing our part to keep the Dahlgren Railroad Heritage Trail beautiful.
