Devil Dog Ultras

Embark on a challenging yet rewarding journey through the picturesque Prince William Forest Park in Triangle, VA, at the Devil Dog Ultras on December 5, 2026. This esteemed event, known for its "strange and happy (and very experienced) group of trail running weirdos" at the helm, offers three formidable distances: 100 miles, 100 kilometers, and 50 kilometers. The course is predominantly single-track trails, winding through rolling hills and occasional technical sections with roots and rocks, earning it a reputation as "sneaky hard" due to the constant, strength-sapping undulations rather than significant climbs. Runners in the 100M and 100K will tackle loops (a 23-mile first loop followed by 19.5-mile subsequent loops), while 50K participants complete one 23-mile loop and an additional 9-mile "puppy loop."

Participants consistently rave about the unparalleled support at the Devil Dog Ultras. Each loop features three fully stocked aid stations—Camp Remi (the start/finish), Camp Gunny, and Camp Toofy—along with three unmanned water-only stations. Expect exceptional volunteers providing "unlimited hugs and encouragement" and an abundance of hot, delicious food options, making it possible to run without a crew if preferred. Crew access is available at Camp Remi and Camp Toofy, with convenient bunkhouse accommodations at the start/finish for those seeking lodging close to the action. Typical race day conditions in early December bring highs around 50F and lows near 32F, though historical data shows unpredictable weather, including possibilities of cold temperatures or even ice, adding an extra layer of challenge and requiring careful gear planning.

Beyond the challenging terrain and comprehensive support, the Devil Dog Ultras fosters a unique sense of accomplishment. The race boasts a rich history dating back to 2016, with its name honoring the nearby Marine Corps Base Quantico. For those seeking to push their limits over multiple years, the Devil Dog Dynasty Challenge offers exclusive rewards for completing various distances in consecutive events, solidifying your legacy as a true ultrarunner. Prepare for a well-marked course and a meticulously organized event that will test your endurance and leave you with unforgettable memories.
