Event Description
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. It was incorporated into an official trail race in December 2017. In 2021, the event was moved to its current 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.
