Get ready for an epic comeback! After being away for six years, this September 26-27, 2026 event is bringing back serious mountain adventures to Estes Park with three awesome options: a grueling 50k bike race over technical terrain, a scenic 50k trail run through Colorado's wild backcountry (perfect for first-time ultra runners with comfortable cutoff times), and a Heavy Half Marathon for those wanting a tough but slightly shorter challenge—all set against the stunning backdrop of Rocky Mountain National Park. Whether you're a seasoned endurance athlete or ready to test your limits on the trails, you'll find your perfect distance here.
