What kind of experience is required to participate in the White Mountains 100?+

The 100-mile counterclockwise loop features over 8,000 feet of elevation gain through Alaska's rugged backcountry, including partially maintained snowmachine trails, rolling hills, black spruce forests, frozen lowlands, and a treacherous mile-long section of frozen overflow.
How long do participants have to complete the race and what support is available?+

Where does the race start and finish, and what are the parking arrangements?+
The race starts and finishes at the Wickersham Dome trailhead at Milepost 28 of the Elliott Highway, about an hour from Fairbanks. Parking is not available at the trailhead; participants and spectators must park in the large pullout across the highway.

Participants should anticipate Arctic temperatures, wind, blowing and drifting snow, water crossings, and potential wildlife encounters along the remote and exposed route through the White Mountains National Recreation Area.
How does the registration process work for the White Mountains 100?+
Registration will open in late 2026, followed by a lottery drawing (date TBD) to select approximately 85 participants. A waitlist will be posted, and the $285 fee is only charged if a participant is selected for the main roster or chooses to fill a withdrawal position from the waitlist.
