As a GUESS I would assume at LEAST 3.5 hours. From the Columbus area it takes me 2.75 (Rte 23-98-4) to get to PKI from my house it takes 1.25. That is with NO speeding...
I know from a fellow GTTPer (UCISECPHUGTDS) it takes him at least 3.5 hours so you've got quite a haul ahead of you. I would highly recommend going to Mapquest.com and it should give you the best route, estimated travel time (this IS Ohio-construction capitol of the US) and total mileage.
Hope this helped!
