I just want to follow up. I have been on the Advair 250/50 2X a day now for about 4 months. I take two puffs of Albuterol about 20 minutes before riding and the regimen seems to be working well. As long as I don't push too hard in the first 15-20 minutes I am OK. Sometimes I have to fall a little behind when the group starts out fast. Still not thrilled with the long lasting broncho component but I guess I shouldn't complain if it is working with no side affects.
