Denali 135

Founded in 2019 by Sean Tracy and Bill McCue, Denali 135 covers the full 135-mile length of the historic Denali Highway point-to-point from Paxson to Cantwell, Alaska — the original 1957 road into Denali National Park, now 21 miles of pavement followed by chip-seal gravel. Runners carry nearly 20 hours of arctic daylight on the summer solstice start, with Denali and the Alaska Range overhead throughout. The 48-hour cutoff, a mandatory support crew with vehicle, and a 50-runner field cap define the logistics. In 2025, 8 of the 135-mile starters finished.
