Furbutt's Backyard 24 Hour
Furbutt's Backyard 24 Hour is the Virginia Happy Trails Running Club's Backyard-format event held over Memorial Day at Meadowood Special Recreation Area on Mason Neck, near Lorton in southern Fairfax County, Virginia. The start and finish are at the Mustang Trailhead, at the corner of Gunston Road and Harley Road under a large horse pavilion.
The Backyard format requires runners to complete a 4.167 miles loop within one hour and be in the start corral at the top of the next hour to begin the next loop. The event is run for 24 hours with a 100 mile limit and entry is limited to 100 runners; entry opens March 23, 2027. A $25 fee is charged to help cover permit and event expenses.
The loop begins with 0.7 miles on a flat, open grassy field, then continues on dirt and crushed gravel bridle trails that are mostly wooded with some sections through open meadows. Elevation gain per loop is about 300 to 350 feet; total ascent and descent for the event is listed as 7,800 feet.
One centrally located aid station under the pavilion will provide water with ice, Gatorade, and some snacks. Runners are expected to bring their own food and personal aid supplies; crews may access only the single aid station and may not contact runners in the corral after a yard begins. Parking is available in the grass field behind the pavilion.
The club does not provide medical care at the event. No medical personnel or medical supplies are supplied on course or at aid stations. Runners are responsible for their own health and safety and should be aware that injuries and medical incidents may occur. Visit the organization's website for the most recent information.
