Furbutt’s 24-Hour Backyard Ultra – Lorton, VA 2026

New this year: We are increasing the registration fee to $25 to help cover expenses for the race. Since we are charging a fee this year, note that you will not be expected to bring any food or beverages to share. We will be providing food, water / ice, and Gatorade at the start / finish area. Please bring any additional food or beverages that you anticipate needing during the race for your personal use. The backyard format is based on Lazarus Lake’s Backyard runs. Runners have one hour to complete the 4.167-mile course. Runners must be in the corral at the top of the next hour ready to start the next loop, or they’re out. In addition to being a challenging run, Furbutt's 24-hour Backyard is also a great way to experience the backyard format. This is an excellent opportunity to run your first marathon, 50k, 50-mile, 100k or 100-mile distance because the backyard format forces you to rest early and often, which can help you run a longer distance than you thought possible.
