General Info

Alaska…….Denali……Big, Wild & Wide Open Places.
With 20,310’ tall Denali and surrounding Alaska Range Mountains and glaciers as its backdrop, the 135 Mile Denali Highway is the setting for the spectacular Denali135, Denali100K & Denali50K Endurance Races. The Denali Highway was the original and only road into Denali National Park from 1957 until 1971 and it is still as breathtaking and jaw dropping today as it was more than 50 years ago.
Hardy and qualified adventurous athletes from around the World are invited to challenge themselves during the Denali100K along the half length of the historic gravel road from scenic Alpine Creek Lodge to Cantwell Alaska…. Adjacent to the entrance to Denali National Park.
Superlative panoramic vistas reach out for miles in every direction bathed in the nearly 20hrs of arctic daylight each day during the race. National Geographic rightly called the Denali Highway one of the top ten most scenic roads in North America.
The Denali100k will be limited to 50 runners and their crew and pacers.

Denali100k Course
The Denali100K is also a point to point race which starts at approx. halfway across the Denali Highway at the Alpine Creek Lodge and then heads west before finishing outside Cantwell Alaska at the same finish line as the Denali135 runners.
Denali100K Runners. Runners and crews will check in at the Alpine Creek Lodge no later than 1hour before (5PM) the start of the race which is at at 6PM on June 20th.
The amazing subalpine scenery begins when racers and crew start at Alpine Creek Lodge at mile 68. The lodge offers rooms and cabins, restaurant and light supplies.
Racers, pacers and their crews press on until they reach the Susitna River Bridge at mile 79.5.
A few miles further at mile 82.2 is Clearwater Mountain Lodge. Bed& Breakfast, Food, Gas and Tire repair. Leaving the Susitna River Valley, the road continues on now with no services or lodging until the end. Runners, pacers and crew need to plan this section well because other than the road and occasional passing motorist, they will be alone on the Denali Highway for the next 50 miles until they reach the finish outside Cantwell. Mount Deborah and Hess keep participants company until, weather permitting, 20,320’ Denali makes it’s appearance to the west and rewards the persistent with jaw dropping views of North America’s tallest peak.
