Distance runners with EIA

LoriLoves2Run

I'm looking for distance runners with exercise induced asthma? I've just finished my 8th marathon and my worst marathon time to date. My previous marathon, I was on pace and had a very frightening attack around mile 20, forcing me to walk the remaining 6. My most recent marathon, I had an attack around mile 6. I recovered with my inhaler okay but was terrified of having another and forced myself to walk/run the rest. To add insult to injury, my hip acted up around mile 14. Murphy, again!! Haha. I'm just wondering how other long distance runners with EIA have dealt with the issue and have possibly overcome it. Paula Radclif has it and she wins marathons but I'm no Paula.
