From the organizers
The Dirty Donut is the first event of its kind to be held on dirt roads. This event has 6 different distances of 4, 16, 26, 42, 62, and 100 miles. Everyone from the very serious racer to those that just want a fun riding experience have a place at this event. Serious racers will opt for the “Sprint” race, which is conducted much like any other gravel race and the winners are the first to finish. “Donut” racers will opt for a bit more strategy in a race where the winner is often not the fastest rider, but the rider who can combine speed with how many donuts they can eat.
