Once again Screamen Eagle is stepping up to provide the prizes for the Fatbike Challenge. As interest in the Fatbike Challenge grows we are receiving questions about prizes and rules. You can get the answer to the former if you scroll down on the Prizes page.

As for the latter, in the interest of fair competition we have adopted a simple rule: All bikes in the Fatbike Challenge must have a minimum tire width of 3.8″ (97 mm) or larger and rims 2.16″ (55 mm) or wider, as explained on this Wikipedia page. 

Take note – we will NOT be measuring tires! Fatbike Challenge competitors must self-police and report non-conforming bikes to race officials at the scorers table.

To enter the Fatbike Challenge check the ‘Yes’ to the “Are you riding a Fatbike?” registration question at BikeReg. If you already registered you can edit your registration. If you can’t figure out how to do that contact BikeReg. Procrastinators can add their bib number to the Fatbike Challenge list at race day registration.
