Go to a chemist and buy a roll of "3m" narrow ( I think mine is about .5cm wide) it doesn't feel very sticky when you first out it on but stick a strip to where you get the chafing since discovering it in December I'm able to wear a heart rate monitor for every run, I'd previously stopped as it was too painful!
