Okay, after yesterday's mega run, I drove to Laurentian Lodge - about a 2.5 hour drive Northwest of Sudbury. The priests of my Diocese are on retreat there this week. My right knee was aching (not my left, as before) so I drove with an ice pack on it.
In the morning, I drove to a flat place (since the Lodge is located in a valley between some pretty high mountains) and tried to run. BOTH knees were killing me, so I packed it in after a half mile. Obviously, I need to take a day of rest.
