IditaFAT distances are 12K or 25K and 50K, but may depend on conditions. On Sunday March 7, Winona trails will be the site of the annual SnoFatShu, consisting of a snowshoe leg of approximately 5K. Snowshoers will arrive back to the transition area to send a partner racer out with a fat bike for a 10K or 20K route. Distance will depend on snow conditions. Once back, the snowshoe runner will head out for the final 5K lap. The race can be done by teams or solo.
