4 Mile Run with Hills

I woke up this morning expecting rain, wind and cold and to my surprise it was relatively warm and still. So I went out for a run I decided to do a harder course and put a 2 mile uphill into it. I felt great for the first 2 miles at about mile 3 though my knee was bothering me a bit I hope the ITB problems are not coming back.... I finished my run though at a good pace did some stretching so I am hoping it is going to be fine, we will soon find out.
