The Human Potential Running Series Presents:
The Sawmill Trail Runs @ Staunton State Park
The Sawmill Trail Runs; first started as a “Fat Ass” event at White Ranch Open Space in Golden, CO in
December 2013. We incorporated it into an official trail race starting in December 2017. In 2021, this event was moved to its new home at Staunton State Park in Pine, CO featuring 50k, 16-Mile, and 8-Mile distance options.
Staunton State Park is a gem within Colorado’s State Park system. From high grassy meadows at 8,100 feet to soaring granite cliffs over 10,000 feet, Staunton State Park’s varied geology, soils, water features, and climate support rare and unexpected plant communities and a rich diversity of wildlife and provide a myriad of outdoor recreation opportunities. The park is located approximately 40 miles southwest of downtown Denver, north of US Highway 285 and about six miles west of Conifer in Pine, CO.
Special Event Notes: Traction devices such as micro-spikes are welcome should conditions permit. Snowshoes will also be permitted in the event of snow depths exceeding 6″. No other flotation devices will be approved. In the event of deep snow and treacherous conditions on the 50k’s first loop, the loop will be closed and we’ll ask 50k runners to endure the 16-Mile course, twice consecutively.

THIS IS A RULES OF THE ROAD RUN. Per our permit requirements, runners must obey all traffic laws and yield to traffic if encountered (this includes vehicles backing out of driveways). That being said, the race is held on low traffic residential streets, and the odds of encountering a vehicle on course are low.
Want to help out? We’re looking for course marshals, hot cocoa slingers, packet pickup, awards & more! Sign up here!
Online registration closes at 11:59pm December 30. If the race has not sold out, all race-day registration will be on-site at packet pickup.
We hope to secure open skate time in EPIC, as usual, as well. This will be updated as soon as confirmation is obtained. If available, you can bring your own skates or rent them on-site for $3. Open skate from at least 6:00pm-7:30pm.

As you run, all of your fans will be able to see you from the start line, then walk less than 1/3 of a mile to see you at two different points before cheering on your finish. This is a very spectator friendly venue and a great way to kick off the New Year!
