Never Summer 100km & 60km – Walden, CO 2026

The Never Summer 100km, 60km and Dirty Double 100 miler will take place almost entirely within the boundaries of State Forest State Park and run between the Never Summer Mountains on the northern border of Rocky Mountain National Park (RMNP) and the Medicine Bow Mountains to the north of Cameron Pass. The first 20 miles of each race will offer a tour of the peaks and alpine lakes of the northern Never Summer Mountains, before the route crosses below Cameron Pass and heads north into the southern Medicine Bow Mountains for more peaks and lakes over the final miles. Cameron Pass sits at the top of the iconic Poudre Canyon and near the headwaters of the Cache La Poudre River, almost exactly halfway between Fort Collins and Steamboat Springs (1.5 hours either way), an hour south of Laramie, WY, and 2.5 – 3 hours from Denver.
