I started C25k the week after I quit smoking. I’m now W2R2. My biggest problem is not shortage of breath but severe calf cramps - I can just about manage 60s but I can’t repeat the 90s runs in full after the first interval.
I realise this must be from clogged arteries from smoking. Does anyone know whether this gets easier? Not looking for medical advice on this forum, only for any experiences anyone can share. Thanks
