The third-annual Devil Dog Ultras will take place on Dec. 1-2, 2018. Registration is now full, but you can add yourself to the waitlist via 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.

For 2018, all runners will receive a Devil Dog–branded Snugpak Jungle Blanket. Runners will also receive a Devil Dog Headsweats hat or Devil Dog Buff. 100-mile finishers will receive a Devil Dog buckle; sub-24 hour finishers get a special Devil Dog One-Day buckle. 100K finishers will take home an awesome Devil Dog Ultras engraved Bottle Breacher bottle opener.

Eligibility

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.
