Equinox Marathon, Fairbanks, Alaska

The Equinox Marathon and Equinox Relay are annual running events held in Fairbanks, Interior Alaska. The 2026 edition is scheduled for Saturday, September 19, and is listed as the 63rd Annual Equinox Marathon and the 33rd Annual Equinox Relay.

Most of the marathon course is on trails and includes a notable climb up and over Ester Dome twice. The event uses a generous ten hour time cutoff that accommodates runners and steady walkers who maintain a consistent pace. Course resources include a detailed course description and a mile marker map.

The races take place near the autumnal equinox in late September. This timing often coincides with the end of the green Fairbanks summer, when leaves turn yellow and orange and trees begin to lose their leaves, and it is usually before winter snows arrive. The event attracts runners, volunteers, and spectators from the local community and is framed by the race history and traditions maintained by the organizers.
