Event overview
The Endure Trail Runs is scheduled for May 16, 2026 at the Pisgah Point Group Campground in Mueller State Park, Divide, CO. The event includes the following distances:
- 12-Hour timed event
- Marathon
- Half Marathon
- 10k
Runner capacity is 225 combined. The 10k, Half Marathon and Marathon carry an 11-hour time limit. The event uses only trail surfaces - double-track and single-track - with no pavement on course routes.
Format, course and logistics
The 12-Hour event uses a loop-draw format: runners pull colored balls to determine which marked loop they will run next; miles are recorded after each loop and a runner’s total is the miles completed within the event window. A black ball triggers either a short time penalty or a brief task; successful tasks earn override tickets that can later exchange an assigned loop for another color. Runners who do not complete a final lap before the event cutoff will lose the miles for that lap but retain previously recorded miles.
There is one main aid station at the Pisgah Point Group Camping Area that serves as start/finish and loop check-in/out. The aid station provides water, electrolyte drink, assorted ultra-style snacks and drop bag access. Camping on site is limited and restricted to registered runners; tent camping is allowed, but trailers and rooftop tents are not. Due to limited parking, spectators and crew are not accommodated and some participants may park off-site and be shuttled to the venue. Finisher awards are given on completion; awards will not be mailed. Weather in the area is variable, with average highs around 57°F and lows around 32°F.
