Registration details

The third-annual Devil Dog Ultras will take place on Dec. 1-2, 2018. Registration is now open at UltraSignup

Registration for the 100-mile race is $205 before Oct. 1 and $240 after. The 100k is $140 until Oct. 1 and $165 after.

A 50 percent refund (excluding UltraSignup fees) will be issued at an entrant's request up until Sept. 30. If space allows, you may be permitted to switch distances until Nov. 1. After Nov. 1, distance transfers will not be permitted. For a refund or to change distances, please send us a note via the Contact section. We’re sorry, but no deferrals.

Below is the 2017 swag. All runners received a Devil Dog Ultras SealLine waterproof dry bag. We love these as aid station drop bags or to store your funky race gear. Runners also received a Devil Dog Headsweats hat or Devil Dog Buff. Sign up for our emails for updates on 2018 gear.



To register for the 100-miler, you must have completed a 50-mile race within the past two years. (This means we must be able to find your name on an official finisher list on a race website or UltraSignup.) There is no entry requirement for the 100k, but trust your gut — if you’ve never run an ultra before, this might not be the best starting point.
