Along with the exercise induced asthma (I take flovent and seravent), how much does the weather affect you? Today was warm and extrmemely muggy, and I was coughing to clear my lungs when I hit rest-stop one (mile 15). Decided to bail and ride back to the start - OK the pending thunderstorm also weighed in on the decision. This isn't the first time I've had lots of trouble breathing when it's very muggy out. So now, hours later I still feel whoped.
