Devil Dog Ultras

Devil Dog Ultras is a challenging trail running event held in Prince William Forest Park near Triangle, Virginia. It offers three race distances: 100 miles, 100K, and 50K. The course features primarily single-track trails with some roots, rocks, and brief technical sections, along with fire roads and rolling hills but no major climbs.

The 100-mile and 100K races consist of multiple loops (five and three respectively), while the 50K includes one loop plus an additional 9-mile loop. Aid stations are well-stocked with food and water, and crew access is limited to certain points. The event fosters a supportive atmosphere with experienced volunteers and encourages participation through a unique loyalty challenge rewarding runners who complete multiple distances over consecutive years.
