About
The Tie Dye 50k is an annual 50K (31 miles) ultramarathon at John Bryan State Park in Yellow Springs, Ohio, on May 15, 2027, starting at 7:30 a.m. The course covers three loops through a scenic limestone gorge.
The race is cupless, so runners must carry their own collapsible cups. Fully stocked aid stations are set at intervals with a variety of refreshments, drop bags can be left at designated points, and newly built restrooms are available. There is a 9-hour time limit, with an early start option for those concerned about the cutoff. Awards go to top runners, with distinctions for the overall standings and for completing the final loop.
