Join us this winter and ride the route that riders can’t stop raving about — the snow-covered, world-famous Birkie Trail. ### Fat Bike Birkie is an Open-Class Bike Race The Birkie Trail Staff groomers share the goal of providing a firm surface to ride on for the races. However, course conditions and weather can vary widely, from hard packed to soft powder snow. We recommend that participants be prepared to race in any course conditions. Just like in the Birkie Ski race, Fat Bike Birkie participants are free to choose different equipment based on the conditions of the course. Bikes should equipped with at least 3.5 inch wide tires, suitable to course conditions. Please note, Class 1 fat bike e-bikes are allowed in the Fat Bike Birkie. At this time, e-bike riders will not be eligible for awards or results placement. You must notify registration@birkie.com or tell us at bike plate pickup if you are riding an e-bike. ## Registration Information ### 2026 Fat Bike Birkie Registration [Register Now!](https://register.birkie.com/?event=f12a816f605d83bcff4d) | | June 10 through November 13 | November 14 through January 15 | January 15 through February 19 | February 20 through Race Day | |---|---|---|---|---| | Big Fat, Half Fat or Fun Fat | $80 | $90 | $100 | $110 | ![50d111b8 79d8 4e37 a92e f34afd649e35 Edited](https://www.birkie.com/wp-content/uploads/2026/01/50d111b8-79d8-4e37-a92e-f34afd649e35-Edited.webp) Registration closes on Saturday, February 28th.
