Alaska Endurance Trail Run
The Alaska Endurance Trail Run takes place June 5-6, 2026 in Fairbanks, Alaska. The 2026 edition is the tenth running of this timed event. Runners compete against the clock to see how far they can go during a set time period. Three timed options are offered:
- 24-hour timed race
- 12-hour timed race
- 6-hour timed race
The start area is at the ski hut near the parking lot behind the International Arctic Research Center on the upper campus of the University of Alaska Fairbanks. The main course is a roughly 6-mile loop on the UAF West Ridge trail system. Trail surfaces include gravel, grass, roots and forest duff. The route passes through forested areas, open fields and meadows. There are no road crossings except for a couple of gravel maintenance roads, and a short paved section of about 300 feet along a bike path; runners can use adjacent gravel or grass there.
Trails are mildly technical in places, with roots, some fallen branches and occasional rocks. Depending on spring breakup and recent rain, some sections may be soggy.
Minors aged 12 to 17 may participate but must be accompanied on the premises by a parent or designated guardian for the duration of the event. A post-race barbecue and an awards ceremony follow the final finish. Visit the organization's website for the most recent information.
