The Circle City Donut Dash is an event that benefits Teachers' Treasures, a non-profit providing free school supplies to teachers of students in need. It offers a unique race experience with two options: the Donut Challenge, where participants consume donuts during the race, and a traditional non-donut 5K. Virtual participation is also available. The event features an after-party with free food and drinks for participants. Awards are given for overall performance, age categories, and costumes, with special prizes for those completing the Donut Challenge. All proceeds support Teachers' Treasures' mission to aid educators.
