From the Organizer

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.  In the Donut races, each race distance has “donut stops” positioned along the race route.  Participants deduct five minutes from their final finish time for each donut they consume at one of our “donut stops” in the race.  The great thing about this race is that there are several different ways for competitors at all levels of cycling fitness to become winners.  The Dirty Donut Race is a family fun event and is truly “A Race for All of Us”.

Sound like fun? It all takes place on Saturday, June 20, 2026. The race will start and finish at the Martin High School in Martin, Michigan.  A very beautiful high quality medal will be presented to every racer that finishes and we have even more hardware for our divisional and age division winners!  As part of their entry each racer will get an event t-shirt and most of the field will get a free BBQ lunch based on when they registered and which race distance they entered.
