The event is organized with a grassroots, community-supported approach and is separate from a similarly named local race that takes place under different management.

This is a "FAT ASS" event, which means low on-course support. Participants should expect limited water stops and fewer porta-potties than in fully supported races. Organizers note there will not necessarily be a race shirt or a beer at the finish. The finish area is near multiple stores. Participants are advised to review start logistics, parking locations, and event information on the event website before race day. Visit the organization's website for the most recent information.
