Event Overview

The Dirty Donut is not your average gravel race. As one of the Midwest's fastest-growing dirt road events, it combines the intensity of competitive gravel racing with a unique twist: Donut Stops. Located in the rolling terrain of Allegan County, this race encourages participants to bring their best speed and their best appetite.

Whether you are aiming for a sub-3-hour 62-miler or just looking to enjoy a scenic, sugar-fueled ride, there is a place for you. In the Donut Division, riders can stop at checkpoints to eat donuts, with five minutes deducted from their total finish time for each donut consumed.

The Divisions

Donut Division: Strategic racing! Eat donuts, deduct time, and win by being both fast and full.
Sprint Division: Traditional gravel racing. First across the line wins.
Specialty Categories: Fat Tire (3.7"+), Single Speed, and Tandem categories are available.

Course Descriptions & Distances

Courses consist primarily of gravel roads, with a few paved sections.

62 Mile (The Grand Tour): The premier distance, covering approximately 2,300 ft of climbing through rural Allegan County with 3+ donut stops.
42 Mile (The Classic): A challenging intermediate distance with roughly 1,400 ft of climbing.
26 Mile (The Bridge): A new distance designed to bridge the gap between intermediate and short distances, offering 540 ft of climbing.
