I'm glad that my question has helped so many and that there is so much positive advice!

Yesterday I rode to my new job for the first time, It's a nice 4 mile trek that takes me through the nature trail I like to ride (except it's an area I never rode till yesterday) and while I wasn't able to get up the gigantic hill, I tried but my asthma was not letting me have it, I did make it up a smaller hill without getting off!
