Which trail in Central Ohio has the most hills per mile? Well by my Garmin it looks like the winner is: Great Seal State Park in Chillicothe - 185 ft / mile. Close behind are Mohican, Zaleski and Clear Creek. How do the local metro parks stack up? Highbanks, Darby creek, Prairie Oaks, Hunters Hollow, Winterhawk, Tunnel trail, and Alum Creek do NOT measure up. Although they are all terrific places to run. If you want to run hills you need to go to one of the top 5.
