I used to be quite fit when I had no car and two kids to perambulate by myself . Now kids are older and I have both a car and a licence to drive it. This means I've done less and less activity in the 4.5 years since I passed, and my life has changed so that I really can't do without most of the driving - school runs, work from a car office, etc. So, the inevitable has happened and I'm now about 1.5 stone heavier, puffier, and much creakier (not to mention 5 years older - ahem...)
However, I still have some residual fitness and haven't REALLY struggled with the runs up to now (week 4), at least not physically, more psychologically. What I'm wondering is whether I'll meet my level at some point on the programme and hit a wall which will take some breaking through, or if I'll be able to move forward incrementally increasing fitness as I go. See what I mean about creating barriers in my head ?
I realise no-one can give me a definitive answer for my particular set of circumstances, but I'd love to hear anyone else's thoughts or experience.
