Narrative:

Three parallel runways cleared to exit one, cross another, and taxi on another. Very familiar with the airport and operations. But turned on second runway and taxied on an active runway. Notified by local to exit. No conflict of traffic. Some distraction in cockpit as instructor and student analyzed and reported a 20K airspeed gain and subsequent balloon and long landing. Classic 'I thought I was doing the correct thing.' moral - save the instruction/discussion: for after critical phases of flight.
