About Devil Dog Ultras

Sat, Dec 6, 2025 • Prince William Forest, VA
This loop course is primarily single-track trails, with occasional roots, rocks, and brief technical section. There are also spurts of fire road and rolling hills but no substantial climbs. The first loop for both races includes the Farm to Trails loop and is 23 miles. The subsequent loops are 19.5 miles and do not include the Farm to Trails loop. The 100k will complete three loops, and the 100-miler will complete five. Runners for the 100k may have a pacer for loop 3. Runners for the 100-miler may have a pacer for loops 3, 4, and 5. Pacers are not allowed to mule — i.e., carry your stuff — or provide any assistance other than keeping you entertained and safely on trail. Pacers can pick up their runners at Camp Remi and Camp Toofy.
