What Makes It Great

Two loops of Front Range singletrack through Pike National Forest and Roxborough State Park, with over 7,800 feet of climbing through Colorado's peak fall foliage. Starting at Indian Creek Campground near Sedalia, the course winds between 5,000 and 8,000 feet past lodgepole pine forests, aspen groves, and striking red rock formations, with distant views of Denver and nearby 14ers. A mid-race drop-down to the 15-Mile is available at the start of loop two for those who need to call it a day.
