Featuring The Dirty Mitten Trail Run and The Dirty Mitten Gravel Bike Race on 9/20, and the Dirty Mitten Gravel Triathlon on 9/21
The Dirty Mitten Gravel Triathlon offers a beginner friendly sprint option (The Shorty), and a more challenging Olympic (The Long One) course, with 4 events at each distance: triathlon, aquabike, duathlon and relay... plus you can join us virtually!

Complete all three races and you will be one of the elite few who can say they tackled the Greenleaf Trust Trifecta! What does that mean you ask? Aside from a lifetime of bragging rights, we will also add an awesome piece of swag to help sweeten the pot. Signup today!
TO DO: Frederick Meijer Garden & Sculpture Park, John Ball Zoo, Gerald R. Ford Presidential Library & Museum
