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 Endurance Race. 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 along the entire length of the historic gravel road from Paxson Alaska, the headwaters of the wild Gulkana River, 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 Denali135 was first run in 2019 by Sean Tracy (44hrs 12mins) with running partner Bill McCue (44 hrs 22 mins). The 2023 Denali135 will be limited to 50 runners and their crew and pacers.
The Denali135 is a point to point race along approx. 131 miles of the 135 mile Denali Highway with an approx. total elevation gain of 8800’. The race starts in Paxson Alaska on the East side of the Denali Highway and finishes in Cantwell at the West side of the Denali Highway.
After checking in at the Historic Gakona Lodge (approx. 3.5hrs drive from Anchorage), Runners and crews will begin the Denali135 at Paxson Alaska…The crossroads of the Richardson and Denali Highways.
For 21 miles the Highway is paved as it slowly rises up from the Gulkana River watershed to the Tangle Lakes area. A chain of Lakes listed on the National Historic Register for its important archeological value. A small roadhouse and lodge (Tangle River Inn) at mile 20 sits closed until a new owner is found.
There the road becomes gravel and gently rises and falls before climbing to 4,086’ Maclaren Summit Pass at mile 36.8. Down from the summit to the Maclaren River Lodge after the bridge over the Maclaren River at mile 42. This lodge offers lodging, a small restaurant, gas and limited supplies.
The amazing sub alpine scenery continues on and racers and crew will come to Alpine Creek Lodge at mile 68 (Slightly more than halfway!) 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 at 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.
At mile 131.8 the road turns into pavement for the last 2 miles to the finish line outside the village of Cantwell.

Finish Line Lodging
The Denali135 race finishes just outside the town of Cantwell near the junction of the Denali Highway and Parks Highway.
There are many options for post race lodging within 30 mins of the finish line. Most are located in and around the Denali Park area. For those opting to rent an RV or do the Car Camping thing, there is ample parking at the finish line for crew RV's and cars as they wait for their runners. There will be basic drinks and food offered at the finish line.
The 2023 Post Race Award Party/Salmon Feast will be held at the Denali Education Center (our race non profit partners) Talkeetna Campus on June 22nd at 5pm. Our wonderful sponsors at Denali Brewing Company will be offering their amazing locally produced libations and there will be live music and space for both tent and RV camping(No hook ups) .
All car rentals should be made the same time as lodging to ensure securing a rental vehicle. Only a limited number of rental car companies rent cars that can be driven on the Denali Highway due to the gravel surface of the road so Spirit Trips has partnered with Alaska 4x4 Rentals to provide competitive rental rates for SUV’s, Jeeps and Trucks that can be used as crew vehicles and driven on the Denali Highway and during your stay in Alaska.
This is a convenient arrangement since Alaska4x4 is located at the Anchorage Airport and make the pick-up and drop off of your rental vehicle super easy and straight forward.
Renting a small RV is another option and going this way eliminates the need for lodging.
