Join us for Wisconsin's most unique fat bike race! Ride on the awesome expanse of Lake Superior ice and enjoy the beauty and fickleness of the greatest lake in the world.


The race is held on the frozen surface of Lake Superior.
Choose between two courses:
10k out and back
20k out and back and repeat.

The course takes place on the remainder of the Book Across the Bay course the morning after. An on-land alternative is in place in the event of unsafe ice conditions.

This is a fat bike race! We require 3.5" wide tires. Studded tires are highly recommended due to the chance of icy conditions racing on the ice.

E-bikes are prohibited.

Registration and after party are located at the Harbor View Event Center at 130 Harborview Drive, Washburn, WI. Harbor View provides us with some fantastic amenities, including indoor bathrooms, event space, a free food buffet, cash bar, live music, and local vendors and bike shops. Plan to stick around for a fantastic after party the afternoon after the race!
