I've just started the couch to 5k running challenge having spent most of my adult years as a sedentary smoker (13 years) with no real concern or desire to get fit!
In November this year my mother was diagnosed with Breast Cancer and I finally had the wake up call I've so desperately needed. I started with kicking the smoking and have not smoked cigarette since her diagnosis and now is the time for the other lifestyle changes - my dismal activity levels being the first of many! I'm on my second go at week 1 (I don't want to run before I can walk so to speak ;-)) and am looking forward to kicking it up a gear at the weekend!
I'm getting married in 2016 and desperately want to start a family too so I do have plenty of motivation but I'd love to hear from anyone in a similar boat and we can help each other change for life.
Good luck to everyone starting the challenge - I know we can all do it!
