Treadmill 16:00 [2]
Walked at 4.2 average, 8% climb.
My best guess on right knee is cartilage. Hmm, maybe my 25-year warranty on arthroscopic surgery to trim cartilage just ran out. :)
There was never any twisting to suggest ligament or tendon damage - also no related soreness. Doesn't seem that stress fracture would 'recover' so quickly each time I irritated it. Also, I might be feeling a bit of looseness in knee. Well, no running for a while. Lots of walking in Louisiana soon - see how knee recovers.
