Hi C2Kers, I would appreciate some advice. I'm really keen to start the C2K programme but I had a bad cold/flu type thing over Christmas, which has more or less cleared up although I still have a bit of a cough. I also have mild asthma. I don't feel ill at all & don't to bother my GP for advice. I'm 49 and generally healthy but not very fit! Would I be OK to start or should I wait? Thanks!
