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 inches and minimum rim width of 2.6 inches, as explained on this Wikipedia page.
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.
