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.
Entry Fees
The above prices do not include taxes and registrar fees applied at checkout. “All-In Pricing” is visible on the registration page on RunSignUp.com
**NOTE** The Sawmill Trail Runs have sold out in each of the previous seven editions of the event. Before the 2025 running, our runner capacity for the event was 200 runners. We added 50 more slots in 2023 and 2024, bringing our capacity to 250 to accommodate more runners. Starting in 2025, our capacity limit will indeed be 250 runners. Once those spots are sold out, a first-come-first-served waitlist will be implemented. In 2024, the first 200 entries were sold before Halloween. The additional 50 were sold out before Thanksgiving. We cannot stress enough the importance of signing up early to guarantee yourself a spot. We cannot guarantee any movement off of the waitlist.

WEATHER: It’s December in Colorado and the weather, as always, is incredibly unpredictable. There have been years were temps have soared into the low 60’s, frigid years with below zero temps at the start, years with dry trails and no trace of winter, and years where a foot of snow has fallen during the event. It is our every intention to host this event regardless of the varied weather and trail conditions. We must note that the health and safety of all runners and volunteers, as well as maintaining the integrity of the park’s trails, is paramount. In the event that conditions dictate a cancellation, our full refund and credit policies will remain intact.
