About the event

The Tanana River Challenge (TRC) is an endurance race for runners, skiers, skijorers, and cyclists. The race offers 25- and 45-mile distances, both consisting of lollipop routes along the mighty Tanana River and through the Rosie Creek forest. Our event is a reincarnation of the much-loved Equinox Ultra-Ski 100k Challenge which went from Nenana to Fairbanks and was run for many years by Audun and Sally Endestad of Fairbanks. We’ve updated it to include more modes of travel, multiple aid stations run by our great volunteers, and new course routes.
