Birkie is a year-round lifestyle choice for thousands of outdoor fitness enthusiasts of all ages and abilities. From its signature Nordic ski race–the legendary American Birkebeiner, established in 1973 and going strong for over four decades–the Birkie has grown to include an exciting array of racing, training, fitness and recreational events and resources, all on the remarkable Birkie Trail.


The ABSF is all about world-class events and that certainly extends to the Fat Bike Birkie – the largest Fat Bike race in the world!  This is the one time you can ride on the snow-covered and expertly groomed Birkie Trail.  Come join us for a guaranteed good time!  Make sure to register soon to reserve your spot!
