3H Trail Half Marathon and DHRT 50K

Prepare for a true summer trail challenge at the 3H Trail Half Marathon and DHRT 50K on August 8, 2026, in scenic King George, Virginia. Known for its "Hot, Hazy, and Humid" conditions, which are part of its unique charm, this event promises a memorable test of endurance. Both the 13.1-mile half marathon and the demanding 50K ultra unfold almost entirely on the Dahlgren Railroad Heritage Trail (DRHT), a converted railroad bed offering a fast, smooth, and mostly flat out-and-back course. Runners will traverse a varied surface of dirt, gravel, grass, and pine needles, with the added benefit of nearly 100% shade from the abundant trees along the trail. While generally flat, runners should be mindful of some gradual inclines, declines, and occasional sections with roots and bog boards. Historical weather for this time of year typically sees highs around 84°F and lows around 66°F, with a 14% chance of precipitation, ensuring a true test of grit.

The race starts and finishes at the University of Mary Washington Dahlgren parking lot, providing a convenient hub for participants. Aid stations are strategically placed to support your journey: the 50K features seven stations approximately every four miles, offering water, Gatorade, and food, including PB&J sandwiches at miles 12, 19, and 27.7. Half marathoners will find water and Gatorade at key points along their course. This cupless race encourages personal hydration, though reusable SpeedCups are available. Beyond the challenge, runners can look forward to custom finisher medals, a choice of technical tank top or t-shirt, and the chance to compete for cash prizes and age group awards, with a special course record bonus for the 50K, a distance that notably held the fastest trail-only 50K times in the US in 2014. Well-maintained by the dedicated Friends of the Dahlgren Trail, this event offers a fantastic atmosphere with enthusiastic volunteers and a sense of camaraderie, all contributing to a highly-rated runner experience.
