This thread has really given me some hope that my asthma might eventually not hold me back so much. I am very much a beginner (I've done a few 10k's in the past but following them I've always had to stop running for a few weeks (which turned into months through lack of motivation) because of asthma flare up's. I'm on Symbicort 400, Montelukast and use ventolin regularly. I've been running regularly for a few weeks now and have a 10k planned at the end of this month. It is really inspiring to read how well you are all doing in spite of asthma I wonder how you judge whether or not to push yourselves when things are a bit dodgy (eg I had a bad night last night and my pf was down this morning but I still went for a run today , but not really sure whether I should have or not?) Sorry Lou Lou - don't mean to hijack your thread x
