Equinox Marathon - Fairbanks, Alaska

The Equinox Marathon is an annual running event held in Fairbanks, Alaska. The 63rd Equinox Marathon and the 33rd Equinox Relay are scheduled for Saturday, September 19, 2026. Registration opens Tuesday, April 21 at 8 a.m.

Most of the marathon course is on trails and includes a climb up and over Ester Dome that is encountered twice. Organizers provide a generous 10-hour time cutoff for the marathon; the event also includes a relay option.

The race is timed near the autumnal equinox, usually in the third week of September, a period when summer vegetation changes color and trees begin to lose leaves. Local volunteers, runners, and spectators commonly participate, and the event is associated with a long local history and traditions.
