Duncan2, back in June when I did my Class 1 I too was concerned and as it turned out I had no reason to. You see, I used to suffer from mild asthma but only used to pop the old Ventolin before a run etc and no other time apart from that; but then about a year ago I came off it completely and managed to run without the need for the Ventolin/Salbutomol. At the Class 1, the nurse noticed that I had put History of Mild Asthma on my form to which she asked if I was on any medication. When I said no, she simply asked me to breath into a computerised Peak Flow machine and after 2 to 3 blows I was told that my capacity was above average so no run for me! I understand that if you come close to the borderline you're asked to run around the block a few times, less than a mile, and then you sit and wait for approx 10-15 mins before they check your capacity again. I know this because there was a guy there who had to do this. I hope this helps to ease your mind a bit. I can remember that I was extremely apprehensive beforehand because a lot rides on the success of your medical. Good luck, I'm sure it will be fine!
