I went for a 4 mile run today.  The beginning of the run went pretty well.  There was some dull pain around the knee, but not too bad.  It seems that resting the knee is paying off.  However, as I passed the 4 mile mark, I felt a sharp pain.  My knee buckled and I went down.  This has happened to me before.  I found out that this is not unusual for those who have the knee injury, chondromalacia.  Honestly, though, I think my knee is recoverying, albeit not fast enough for me.  Going out on these little test runs are helping me gauge my progress.  Of course, it is also slowing my recovery.  It really shows me that I need to keep my aerobic conditioning up with non-impact training like cycling.  I just feel I need to keep my legs conditioned to handle a long run like the marathon.

This evening I did a chest and back workout.  I find that I kind of miss doing P90X.
