Running and ex-smokers.
I started running about 3 weeks ago on a plan similar to the Couch to 5k plan. Basically I run 1 min then walk 2 mins then run 1 min and so on, upping the repetitions until I can run 5k comfortably. Last week I was on 6 reps and this week I am supposed to be on 7 reps but I am finding it hard, so I am sticking to 6 reps until it gets easier.
My question is, no doubt the fact I was a smoker until 3 months ago is affecting my lung capacity, but does anyone know how long it's going to be before I can run for a minute wthout wanting to die? The article I use states that, if I can't carry on a conversation then I am working too hard, but if I work any less hard I'll be walking! I would love to run a 5k fun run next year but the way I am going it's going to take years to get to that stage.
I know I have really only just started and I was inactive for years before this year, but any advice would be gratefully received.
ETA: It seems that my problems may not be so much a result of smoking as more to do with the fact I haven't done any hard exercise for 20 years because I was a smoker. This is all interesting stuff guys. Thanks for all your replies.
