I'm 52 and have never run, ever, even for a bus. I had knee surgery in my teens which has provided a plausible excuse my whole life. So I'd be grateful for answers to what may seem (to normal people) like some very stupid questions about this programme.
1) how do you know when you're ready to go on to the next week? Or should I assume I move on if I've managed the previous session? - I've done 2 sessions of week one...once I've done my third do I go on to week two even if it's still really hard?
2) can I do a session indoors? I work away from home a lot, for example next week I'm in a hotel in central Birmingham. I'm not confident about going out in the city centre, I don't think the middle of town would be a pleasant experience but I don't want to miss the session, there's no gym at the hotel (and I'm not ready for that in any case) can I run on the spot in my room and get benefit from it...does it count?
3) if I go out in the morning, should I eat/drink something first?
4) I'm currently full of enthusiasm, how do I keep that going when I'm in a miserable hotel room on a gloomy February night?
