Search for and check out the "pursuiters cough" threads and asthma/exercise induced asthma threads. There have been a few of them over the last couple of years.

I am a road racer get exercise induced asthma after a particularly hard time trial (a race discipline). Sometimes I have trouble breathing 'normally' for up to half ann hour after race end, and often have a dry cough for anything between 1-3 days after. i use no medication for this.

I do get asthma ocassionally also - particularly in summer during hayfever season. I also was given an inhaler to help my bronchials with a 4 week winter flu I have been battling.
