Provided I progress to week 8 on Monday (and not so sure after a really bad W7R3 today), week 9 will coincide with a week abroad, when it is highly doubtful that I'll have time to finish off the C25K programme. Should I repeat week 8, or move even further back when I get home again? I expect to return home absolutely exhausted, so I very much doubt I'll be in a position to simply start where I left off, i.e. do week 9 then.
I'm reminded of what a friend, a former professional ballerina, told me once: when she was 18, she could take a week off and only need a day to return to full form. By the time she was in her 30s, she needed a week to return to full form after taking day off. So on the assumption that age probably plays a part in exercise programmes as well, I'd be particularly interested of hearing from those in my own age group, i.e fairly unfit mid-40s.
