Fat Bike Birkie

Fat Bike Birkie- March 9th, 2024

The Fat Bike Birkie, Presented by Freewheel Bike, is the premier on snow bike event in North America. Riders test their skill and endurance on the professionally groomed American Birkebeiner Ski Trail!

THREE events to choose from: The Big Fat 47K, The Half Fat 21K, and the un-timed Fun Fat 10K Tour – there is something for every rider!

There are no restrictions on 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.

E-bikes are not allowed for any event of the Fat Bike Birkie on Saturday, however, may be ridden during Friday’s pre-ride of the trail only.

No special equipment classes will be recognized in the Fat Bike Birkie results or awards. Tandems bikes are allowed, but there is not a special class and will not be eligible for awards. Each tandem rider must register and contact registration@birkie.com to ensure the proper results are shown.
