Getting injections on Monday

I am looking forward to injections in my knees on Monday and some relief of the aching.  In the meantime, I have a 5K on Saturday and then half marathons every weekend for a while, starting with Houston on January 18th.  It was about 40 degrees when I ran this evening.  Cold, but not as windy as yesterday.  I ran 3 miles on the streets around the campus.
