Registration details

The second annual Devil Dog Ultras will take place on Dec. 2-3, 2017. (We've been told these dates will be ice storm–free.)

Registration is closed, and the deadline for refunds and distance transfers has passed. We’re sorry, but no deferrals. In the highly unlikely event that inclement weather or another situation forces the cancellation of the race, the race director has full discretion on how to handle any refunds or deferrals.

All runners will receive a Devil Dog Ultras SealLine waterproof dry bag. We love these as aid station drop bags or to store your funky race gear. Runners will also receive a Devil Dog Headsweats hat or Devil Dog Buff.



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.
