Alaska Endurance Trail Run

June 5th 2026
Fairbanks, AK
6 Hours | 12 Hours | 24 Hours

The Alaska Endurance Trail Run is a timed race, meaning that runners race the clock to see how far you can go in the allotted time. There are three options: a 6-hour race, a 12-hour race, and a 24-hour race; sign up for any of the three. Most races will finish at the same time, which usually make for an exciting completion of the day (particularly for our timers!). Immediately following the final finish, the post-race BBQ party will start, with the awards ceremony as soon as results are ready.

It worked out great last year, so once again 6-hour racers can opt to start at either 8AM or 2PM on Saturday. And 12-hour racers can start at either 8PM Friday or 8AM Saturday.

The starting area will be at the ski hut near the parking lot behind the International Arctic Research Center at UAF. This is the building adjacent to and on the north side of the Geophysical Institute in the upper campus of the University of Alaska Fairbanks. The address is 930 Koyukuk Drive, Fairbanks, Alask
