lifesaver-
I have asthma too.
I run with my inhaler tucked into my waistband--and definitely some runs are worse than others as far as me sucking on the damn thing.
But my trainer/running coach has taken my asthma into consideration in my training schedule, and I do most of my training indoors on a treadmill which helps tremendously... gotta love that filtered air thing! lol I run outdoors once a week--this time of year tends to be worse for my allergies and asthma than the summer----running at the beach seems to work better for me than in the city--and I also fare way better in San Diego's climate than in L.A.'s (yes folks, there IS a difference!)--so I am hopeful that I will get thru the marathon without any major asthma attacks.
