I knew it would happen eventually. All runners have problems with their knees, right? Mine started right at the beginning of my run today. It is a little twinge that happens on the medial part of my knee cap. but after about a mile, it goes away. It is more than uncomfortable, it actually is pain. I'm not sure how serious it is, or if I should do anything more than icing my knees after my run. I did 7 miles this morning and I have 5 miles on the calendar for tomorrow. I guess I'll just wait and see how they feel tomorrow.
