Denali 50K

The Denali50K is a challenging ultramarathon held along the historic Denali Highway in Alaska, offering runners breathtaking views of Denali and the Alaska Range. The 50-kilometer course starts at Maclaren Summit, the highest point on the Denali Highway, and descends northwest through glacial landscapes, including Thermokarst, Eskers, and Kettle lakes. Runners pass a single aid station at Clearwater Creek Wayside before finishing at Alpine Creek Lodge near Denali National Park. Limited to 50 participants, the race allows support crews and requires qualifying marathon experience. The event features nearly 20 hours of Arctic daylight, a unique Alaskan finisher’s medal, and a post-race celebration at the Denali Education Center.
