The 2023 race date is set for Saturday March 18th!
Welcome to the Tanana River Challenge.
Local time: 5:20 PM
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.
