Felt sorry for the flight shool ever since.
No reason to feel guilty….as you climbed you would have been pulling less and less power. As long as temps, pressures and RPM were in limits during your long climb and descent it should not have caused any engine problems. Probably much, much less wear and tear on the engine, drive train and airframe than doing practice confines for the same amount of time for example.
