  Don't miss out on the opportunity to enjoy the beauty of the Dahlgren Railroad Heritage Trail. Sure, these races are held in August. In Virginia. That's the bonus challenge! All runners will receive a tank top or t-shirt (your choice!) and a finisher's medal.

  Both race courses are beautiful, scenic out and back courses on a mostly flat, smooth rails to trails course. There are roots and bog boards in sections of the course - use extra caution in these areas.

  Cash prizes, great competition, good food, and awesome swag all make this a memorable event. There is a 4-hour time limit for the half marathon and an 8-hour time limit for the 50K - runners and walkers are welcome!

  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.
