There is a ride put on by the Akron bike club in August that is either 75 miles one way starting in Canal fulton or 50 miles each way starting in Wilmot. Both go to Coshocton for an overnight, you either camp or they provide hotel rooms at additional but reasonable cost. Me and my wife have done the 75 miles route the past two years and we both agree it is the most beutiful ride you can do in Ohio.
I also have some routes we do on our own in the Amish part of Ohio that are very interesting and quite scenic.
How far are you wanting to drive?
The Cuyahoga Valley is another nice area to ride!
