having knee pain

Your sore knees could be due to tight i.t. bands, I would suggest hamstring stretching, riding a stationary bike, icing after you run. If you take a break from running, say longer then 48 hours putting heat on your knees (heating pad of jacuzzi) will help increase blood flow. Also where are you running? Sidewalks and the road can be brutal on your knees. Stretching surrounding muscles are key I roll my feet out with a tennis ball, definitely strengthen your ankles that can never hurt. One good easy ankle strengthener you can do while watching t.v. just sit down raise one foot and spell the alphabet out only moving your ankle do up to 3 sets. I hope this helps.
