Don't miss out on the opportunity to enjoy the beauty of the Dahlgren Railroad Heritage Trail. Sure, it's held in August. In Virginia. But that's why it's known as the 3H Half: it's HOT, HAZY, and HUMID. All runners will receive a technical tank top and a finisher's medal. This is a beautiful, scenic out and back course on a mostly flat, smooth rails to trails course. Cash prizes, great competition, good food, and awesome swag all make this a memorable event. There is a 5-hour time limit for the half marathon - runners and walkers are welcome! Need a longer challenge? There's a 50K option that kicks off at 6:30am!See All Event Posts
