Tempur-Pedic = Free Birkie Entry!

Fat Bike Birkie is an Open-Class Bike Race

There are no restrictions the specific tire size allowed. The Birkie groomers are some of the best in the world and have the goal of providing a firm surface to ride on for the races. However, we cannot control the weather and the course conditions can vary widely, from hard packed to soft powder. Just like in the Birkie Ski race, Fat Bike Birkie participants are free to choose different equipment based on the conditions of the course. We recommend that participants be prepared to race in any course condition, on a bike equipped with at least 3.5 inch wide tires.

No special equipment classes will be recognized in the Fat Bike Birkie results or awards
