The 45NRTH Fat Bike Birkie is the premier on snow bike event in North America. Riders test their skill and endurance on the professionally groomed American Birkebeiner Ski Trail!
Two days of fun! Friday, March 8 – Check out the Fat Bike Birkie EXPO and Fat Bike Demos! March 9 – Race day and a Post-Race Party in the Great Hall!
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.
No special equipment classes will be recognized in the Fat Bike Birkie results or awards
The Fat Bike Birkie Race Courses will be groomed and marked for pre-riding on Friday, March 8 from 10:00 am to 3:00 pm.
Please note that riding bikes on the Birkie Trail during the winter is only allowed on the days designated for the Fat Bike Birkie event. However, winter bike riding can be accessed from many of the trailheads utilizing the Chequamegon Area Mountain Bike Association trail system. Trail conditions can be found on the CAMBA Winter FAT BIKE page.
All long race participants must be at least 18 years of age on race day. All short race participants must be at least 13 years of age.
This event has a participant cap of 1200. The deadline for requesting a race change is the same day/time that registration closes.
