Tie Dye 50k

The Tie Dye 50k is an annual ultramarathon event taking place on May 17, 2025, in Yellow Springs, Ohio, at the scenic John Bryan State Park. The race features a three-loop course, each approximately 10.3 miles long, showcasing the park's beautiful limestone gorge and natural landscapes. Participants are encouraged to bring their own reusable cups, as the event is cup-less, promoting sustainability.

Aid stations will provide various refreshments, and runners can manage their own drop bags at designated points. Awards will be given to the top finishers, and all participants who complete the race within the 9-hour limit will receive a finisher's award.
