Race Details

Devil Dog Ultras is a 100-mile, 100K and 50K event in northern Virginia put on by a strange and happy (and very experienced) group of trail running weirdos.

Our 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 is 23 miles, and subsequent loops are 19.5 miles. The 100k will complete three loops, and the 100-miler will complete five. 50Kers will complete one loop plus a few extra. The course will be well-marked.

Each loop has three fully stocked aid stations (Camp Remi start/finish, Camp Gunny, Camp Toofy) and three unmanned aid stations (RP Alpha, Bravo, and Charlie) with only water. Crew are permitted at Camp Remi and Camp Toofy only. There’s no crew access at Camp Gunny or the RPs. You can run our race easily without crew, our volunteers offer unlimited hugs and encouragement and our aid stations are so stocked you’ll have plenty of hot, delicious food choices that you won’t be hungry.

Runners have 9 hours to complete the 50k, 20 hours to complete the 100k, 32 hours to complete the 100-miler.


The 100-miler is $275; 100K is $230; 50K is $115. The price will increase on Mar. 1 to $295, $245 and $125 and on Oct. 7 to $320, $265 and $135.
