The Silverheels Trail Runs @ COMO ROUNDHOUSE
The Silverheels Trail Runs take place at an average elevation of over 10,000’, in one of the most visually
stunning areas of Colorado. The course features a mixture of single track trails and fire roads, with a few stretches of dirt road; it takes runners through high alpine and sub-alpine meadows loaded with wild flowers, with expansive views of the South Park Valley and beneath the towering "Decalibron" 14er's. You'll run through ghost towns, past abandoned mines, awe at the wildflowers in full bloom, and dance under the watchful eye of Silverheels Mountain herself and the ever stunning Milky Way Galaxy. Our 10-Mile and 18-Mile options are run on the gorgeous Gold Dust Trail traveling through massive aspen groves, over many high mountain creeks, through old mining encampments, and along a miners ditch hand dug by those in the late 1800s.
