Silverheels Trail Runs

The Silverheels Trail Runs are held in Como, Colorado, with the event hub located at the Como Roundhouse. This trail running event takes place at an average elevation of over 10,000 feet, navigating through the high alpine and sub-alpine meadows of the South Park Valley. The terrain consists of a mixture of single-track trails, fire roads, and stretches of dirt road.

Participants traverse a landscape that includes historical ghost towns and abandoned mines, situated beneath the Decalibron peaks and Silverheels Mountain. The routes pass through aspen groves and across high mountain creeks. Specific sections of the shorter courses follow a miners ditch hand-dug in the late 1800s along the Gold Dust Trail.

Available race distances include:

  • 10.8 miles
  • 19.1 miles
  • 38.3 miles (60k)
  • 53.8 miles (50-Mile)
  • 63.1 miles (100k) requiring specific qualifier conditions
  • 106.2 miles (100-Mile) requiring qualifier and volunteer conditions

The event scheduled for July features local flora such as wildflowers in full bloom. Due to the timing and mountain setting, participants on longer courses may travel under the night sky. Registration for all distances typically opens and closes in December of the preceding year. Visit the organization's website for the most recent information.
