I run from time to time for a differant kind of cardio workout. I haven't run since last fall (CAN NOT run in the cold, yuck!) so I am not adjusted to it. Yesterday I ran 3.5 miles (the most I have ever done is 4 miles) and was so excited that I was in such good shape I could do this much without working up to it. I workout 4 times a week so I'm pretty fit. During my run it wasn't getting short of breathe, or side stiches or even leg fatigue that was getting to me. It was my hips mainly and my right knee. I figure my knee was sore since being right handed I probably put more pressure on it than the left. But my hips are still rather sore today. Does this go away as I get use to running or is this a sign that I should be careful and maybe over doing it. I had just fun running I really hope it is something I can work on and increase in mileage.
