Race Day Weather
Cool morning, ideal running weather
Runners will face a temperature range from 41°F at the start to 50°F by the finish, with average humidity around 79%. A light tailwind at 5 mph will aid performance, but gusts up to 21 mph may provide occasional challenges. Maintaining a steady pace while hydrating regularly will be key to optimizing performance in these conditions.

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.
