Thanks for all the responses! The ride today was the LBC 20 miler which was supposed to be a #1, but the hills in the park and through Mockingbird Valley made it more of a #2-3. I don't believe I have exercise induced asthma....KY allergies though. My beautiful Felt f80 is only a couple of months old and I love it! I am still a newbie to the sport so I am still getting used to the gears....BUT I have discovered how freakin' competitive I must be because I try really hard to keep up. I will up the mileage and add a few hills for practice. Thanks again, yall!
