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 all races is 23 miles, and subsequent loops are 19.5 miles for the 100 mile and 100K. The 100k will complete three loops, and the 100-miler will complete five. The 50K will complete one loop plus a 9 mile loop. The course will be very well-marked.

Each loop has three fully stocked aid stations (Camp Remi start/finish, Camp Gunny, Camp Toofy) and three unmanned aid stations (Resupply Point (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 are exceptional and offer unlimited hugs and encouragement! 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; and 50K is $115.

Bunkhouse Reservations

We’ll once again be offering up 75 beds in the Camp Remi (start/finish) bunkhouses to registered runners on a first come, first served basis. If you’d like to sleep within eyesight of the start, this is for you. Each bed will be $30 total for Friday and Saturday nights; you must be moved out by noon Sunday afternoon. Don’t want to sweat the deadline? We’ll have a place to store your overnight gear before the start while you run in circles. Bunkhouse vehicles will be parked in a remote lot (~ 1 mile from the start/finish). Shuttle service to your vehicle will be provided Friday evening and post-race. Reserve a bunkhouse bed here.
