3H Trail Half Marathon + DHRT 50K
About this race
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 (including FREE MooThru ice cream for finishers), 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!
