Welcome to the Tanana River Challenge



Join us for our 4th annual event on Saturday, April 2, 2016**.

** Unfortunately due to rain and deteriorating ice conditions we’ve had to cancel the 2016 TRC. Please check our Facebook page for details and join us on Saturday for a casual meet-up. **

Have you ever dreamed of a spring traverse up the frozen Tanana River around Fairbanks? Did that vision also include aid-stations and a party afterwards?

The Tanana River Challenge (TRC) is an endurance race which includes runners, skiers, skijorers, and bikers. This year the race course loops around the mighty Tanana River and Rosie Creek forest; where you can choose between 25 and 45 miles distances.


Our event is a re-incarnation of the much-loved Equinox Ultra-Ski 100k Challenge which went from Nenana to Fairbanks and 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 have embraced new course routes.


The TRC is part of the Endurance North family of races including the White Mountains 100 and Chena River to Ridge.
