Race Info
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.
