Narrative:

Landing on runway 10R at cmh. Planned on long rollout to turn off closer to assigned gate. Missed taxiway to gate. Rolled to runway end. Began to turn off but noticed it was active runway 23/5. Since I was not cleared to taxi onto active runway and there was an aircraft on final behind me, I opted to taxi onto what I thought was a displaced threshold and then off the runway on a taxiway located at the end of the displaced threshold. I later found out this is a repositioned runway end line. After I had taxied about 20-30 ft onto the overrun, the tower asked me why I had run off the runway. The commercial 10-7 chart shows this area as an active taxiway. The tower then cleared me for a 180 degree turn and off the runway at the runway 23/5 junction. Fatigue -- over 8 hours flying first day after short layover. Unfamiliar -- over a yr since I had been at cmh. Trying to be too safe not turning onto active runway. I did not realize I had done anything wrong until the tower asked me why I ran off the runway. In fact, I'm still not sure I did anything wrong since the area is depicted as an active taxiway. Up until about 2 yrs ago, this area was used as part of the runway.
