You can do this. I am also, asthmatic. I've been running for about a year now. I do fine, that some seasons kick up my asthma. I do recommen that yoy keep your inhaler close at hand. Run a little slower, try to inhale through your nose and out your mouth. I also, noticed as time goes by the less I have use it. Good luck. If you still have problems with your asthma while running, please see your doctor.
