Other trail races within 54 miles
The Snow Mountain Ranch 50K is a high-altitude dirt trail race set in Colorado's Rocky Mountains at the YMCA of the Rockies near Granby. Three loops on an out-and-back lollipop course take runners through rolling hills and pine forests, climbing to 9,844 feet with 1,412 feet of gain per loop. The race rewards early starters with crisp mountain air and September fall foliage. A mandatory loop turnaround cutoff (begin 3rd loop by 6-hour mark) ensures all finishers cross the line by 3:00 PM.
