There are many reasons for hurting knees when running. Running is just not a beginners sport. For me it was a muscle imbalance - relative to the average my front thighs were at 130%, while my back thighs were at 70%. I did more than one year resistance training to get even that imbalance out. Now I can just run without knee pain anymore.
