Welcome to the Equinox Marathon and Relay site! The Equinox Marathon is the premier running event in Interior Alaska. With most of the course on trails and a challenging climb up and over Ester Dome—and up and over it again!—it is a challenging marathon that will test your running abilities. But don’t worry if it seems too overwhelming! Our generous 10 hour time cutoff is great for walkers who can keep a steady pace, and you can do roughly a half of the course by doing the half marathon.

The classic cross-town clash between rivals East vs. West on the gridiron lived up to the hype, while history was made at the 60th running of the Equinox Marathon. While fish will continue to be reeled in, the run of the 2023 Fishing Report comes to an end.
