I have just realised the power of the ice pack. Well in week 6 I did and I'm now on 9. It could just be a picnic block wrapped in a towel but when I had a sore knee I found one in the freezer we bought in boots months ago for hubby's bad leg. It just fits its own case and moulds to wherever is tender. Now I know we have it if I have an ache or tender part I just use it and it really helps.
I think it's a invaluable aid when running and usefull for so many things
