This is just a first post to say "Hi" and thanks for a forum full of great advice for beginners and a mountain of motivation for anyone interested in cycling to help with weightloss. While I'll be happy to join the ranks of Neil_B's new spiders, truth is I've been lurking here for a couple of months soaking up some helpful advice.
In my case the "discovery" that I had a problem came after going for a ride on a MTB that we'd brought for one of our sons who had wrecked his car and was still recovering. I think I made about half a block before running out of breath and out of legs. Now, my last memory of riding a bike was a 30 mile trip from home to the local ***** club and back again. However a bit of mental arithmatic forced me to concede that this was 42 years and uncountable packets of cigarettes ago coupled with a great number of years in a pretty sedentary job. So here I am at 5'9" and 250lbs, having quit smoking over the last two months, and with a well fitted Trek FX7.1 (bottom end I know, but it rides just fine with a B17 on it !! ) that I've just managed to ride 115 miles for the month. I'm over the moon with this as a first serious month of riding.
And if there are any ex smokers I'd sure like to here your experiences, as the lack of lungs is a definite issue at the moment.
