63-mile point-to-point through Colorado's mining country from mountain start to historic Roundhouse finish
Other trail races within 34 miles
A 100% point-to-point ultramarathon from the Burning Bear Trailhead in Grant to the historic Como Roundhouse, the Silverheels 100K shares its start with the 100-mile and traverses the same high-alpine terrain of Colorado's South Park through mountain passes, wildflower meadows, and historic mining areas. Runners climb to 12,000'+ passes and stay predominantly above 10,000' throughout. With over 10,000 feet of climbing across 63 miles, it's a substantial high-altitude challenge that requires a recent qualifying race for entry.
