The GPS100 event developed out of our love for Great Seal State Park, Scioto Trail State Park and Forest. These Parks have some of the best single track and gravel roads in Ohio. Add in the pavement connecting the two and we created a multi-surface challenge unique to southern Ohio. This event showcases the world class cycling opportunities that surround Chillicothe. Proceeds from the GPS100 go directly to help youth development cycling and build and maintain trails at both State Parks.
