And when I lunge her it never has been more running than she would have if she was able to go outside; basically I let her run as much as she wants just keeping it in a circle and when she slows down we are done.
It's the circle part of lunging that causes the biggest issues for youngsters. She doesn't have the coordination yet to be able to carry herself correctly in a circle for that long. This will wear excessively on her underdeveloped joints. It has nothing to do with how fast or how long you let her run for, it's the actual physics of lunging that is the problem.
