I find that bicycling doesn't effect my asthma (however, a big trigger for me is external allergens, so I tend not to go out if everyone has cut their grass, or pollen is sky high, etc.) I do run with the c25k app - I use my rescue inhaler before and keep it with me.
I honestly think that the running has helped improve my lung capacity, but I could also be experiencing some relief in asthma symptoms because I've lost so much weight.
I would go to the doctor and talk to them about it. Are you on a steroid inhaler or do you just have the rescue? I actually can't function at all without my steroid inhaler. I'm using Qvar right now, because my doctor had some concerns about my long long LONG term use of Advair.
