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!

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
