Endure Trail Runs

Endure Trail Runs

The Endure Trail Runs is an annual trail running event held at Mueller State Park in Divide, Colorado. The event takes place at the Pisgah Camping Area and utilizes a course consisting entirely of single-track and double-track trails with no paved sections. The event has a total runner capacity of 225 participants across all distances.

Participants can choose from several formatted distances and timed challenges:

• 10k
• Half Marathon
• Marathon
• 12-Hour Timed Run

The 12-Hour Timed Run features a unique format where runners determine their course by drawing colored balls from a bucket. Each color corresponds to a specific marked loop. Runners continue to draw and complete loops for up to 12 hours, with their final result based on the total mileage accumulated. A specific "Last Runner Standing" version of the 12-hour event is also available, where runners must complete loops within a dictated pace to remain in the competition.

The 10k, Half Marathon, and Marathon distances have a generous time limit of 11 hours. Runners in the Half Marathon have the option to drop down to the 10k during the race and still receive a finish time.

The event provides one central aid station at the start and finish area, which remains fully stocked with water, electrolytes, and snacks. This location also serves as the access point for runner drop bags. Participants receive a gender-specific shirt and a finisher's medal upon completion of their chosen distance or at least one loop of the 12-hour event.
