The GPS100 event developed out of our love for Great Seal State Park and Scioto Trail State Park and Forest. These parks have some of the best singletrack 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 a local NICA Mountain Biking team and build and maintain trails throughout Ross County.
