The Ohio Parks 25K Challenge

The Ohio Parks 5 X 5 Challenge (25K: Dayton Area) is a one-day, 25K running event in Germantown, Ohio, featuring five 5K races across five Ohio parks. Runners traverse a mixed-terrain course including pavement, grass, dirt trails, and single-track with rolling hills, offering a true test of versatility and stamina. The lineup includes Germantown MetroPark, Sycamore State Park, John Bryan State Park, and Yellow Springs Brewery on the Little Miami Scenic Trail, with a fourth park listed as TBD.

Known for a Wolf Pack community vibe, the event provides finishers medals and sponsor products, and requires completing each 5K in under one hour. Aid is available at Start/Finish; there are no on-course water stations. Visit the organization's website for the most recent information.
