Test your limits at Rocky’s Backyard Ultra, a one-of-a-kind endurance race set in the stunning mountain scenery of Estes Park. This event follows the “last runner standing” format where participants complete a 4.167-mile loop every hour on the hour until only one remains. Whether you’re running to push your personal best or cheering from the sidelines, it’s an unforgettable way to experience the grit, determination, and beauty of the Rockies.
