The Alaska Divide is an unsupported bikepacking adventure crossing the vast wilderness of Alaska, from Anchorage in the south to Deadhorse on the Arctic Ocean. Following remote highways and gravel roads through the Last Frontier, the route takes riders from the forested landscapes of southern Alaska, across the Alaska Range and into the Arctic tundra beyond the Arctic Circle.
The route covers approximately 1,700 km (1,056 miles) with 17,700 metres of elevation gain. Around 50% of the course is unpaved, combining gravel and dirt roads with sections of paved highway. One of the defining stretches is the Dalton Highway, a remote road originally built to support the Trans-Alaska Pipeline, where resupply opportunities are extremely limited.
Starting in Anchorage, riders travel north through the Denali region and across the remote Denali Highway before reaching Fairbanks. From there, the route follows the Elliott and Dalton Highways towards the Arctic Circle, crossing the Brooks Range and the challenging Atigun Pass before reaching Deadhorse near Prudhoe Bay.
There is no overall time limit, and riders must complete the journey entirely under their own power. The organiser provides the GPX route and live tracking but no logistical or on-route assistance. Participants are responsible for navigation, food, accommodation, repairs and emergency planning, making this a genuine test of self-reliance in one of North America’s most isolated environments.

Based on this event's terrain, difficulty and riding style you might like these ultra events.
At 1680 km with 17700 m of elevation gain, Alaska Divide is roughly the distance of 40 marathons back to back, with climbing that adds up to more than 2 times the height of Mount Everest.
A Hardtail MTB is the right tool for Alaska Divide. Set it up with 2.2-2.4" Tubeless rubber and gear it low — a 30-32T (1x) chainring and 10-52T cassette will keep you spinning on the steeper sections.
We rate Alaska Divide as Extreme overall. Riders should be ready for seriously technical, unforgiving terrain throughout, steadily rolling, with a healthy amount of climbing elevation gain, and cool conditions.
Alaska Divide runs on August 14, 2027, placing it firmly in the summer riding season, with long daylight hours, though heat can become a real factor.
Surface-wise, expect off-road throughout Alaska Divide — 2.2-2.4" Tubeless tires are a safe bet.
