Devil's Den Ultra

Devil's Den Ultra is scheduled for October 10 - 11, 2026 in Bradford, Vermont, at 1250 Chase Hollow Rd. The event uses a loop course on Wright's Mountain. The course is described as a 10K loop; another reference describes the loop as 6.4 miles. The trail surface ranges from easy runnable sections to steep, rocky and rooty terrain. The course begins with a steeper climb to the peak, followed by a downhill through woods and a return to the start/finish. There is one road crossing near the start and the loop begins on private property; runners are asked to remain on public trails when training.

The event offers these race options:

  • 30-hour
  • 12-hour
  • 10K loop (course also described as 6.4 miles)

Race entries will be capped at 100 runners total. Registration closes October 8 at 11:59 PM ET; if a waitlist forms, applicants will be notified by October 6, 2026. Runners in the 30-hour event who do not register by September 1, 2026 may not be guaranteed an event hoodie or shirt. The organizer states there are no refunds.

Start/finish and pit area details note parking at the start/finish. 12-hour runners receive space for a drop bin that may be exposed to the elements; bins should be compact to allow room for others. 30-hour runners receive a 10' x 10' pit area for gear and tents; pre-registration the evening before from 4:00 PM to 8:00 PM allows early setup and tent placement for 30-hour entrants.

Finishers receive a themed upside down Devil tarot card. Additional tarot cards and awards are given by performance milestones in the timed events, including Sun and Moon cards for top day and night miles, a World card for 50 miles, a 10 of Pentacles for 100K, and a belt buckle for 100 miles. Top runners in each distance receive a Devil's Skull. The organizer indicates payment plans may be available for some entrants. Visit the organization's website for the most recent information.
