Hi. I have reluctantly come to the conclusion that I may have this problem. Had several instances of having to stop on races after a couple of k...no breath, can't maintain speed etc. Saw the doctor and tried an asthma inhaler but follow on appointment concluded that this isn't the problem or solution. Going back to see dic in a couple of weeks.

Anyone with advice, I would be delighted to read more
