About the race
The Dirty Mitten Gravel Triathlon is a two-day gravel racing event in Middleville, Michigan. On Saturday, participants compete in a Gravel Bike Race with 10-, 28-, or 50-mile options. Sunday features the Gravel Triathlon, offering Sprint- and Olympic-distance courses that include a swim, a gravel-bike leg, and a trail run.
In 2024 it served as the USAT Gravel National Championship. Special features include the Greenleaf Trust Trifecta—completing all three events earns a swag item—and The Dirty Double for racing both days. The event has also been highlighted by Triathlete Magazine as a major multisport challenge.
Crucially, it is described as a two-day weekend of gravel racing. Visit the organization's website for the most recent information.
