Having completed the third run of week three, I am just wondering how I should feel regarding my readiness to move on to week four? Should I be feeling 'ready' for week four or should I be feeling that week 3, run 3, was hard, and I was still puffing and panting but managed to complete the two lots of 3 minutes? I am really not sure if I should keep going til it's comfortable, or should I just be completing the week and then moving on regardless of whether I have found it difficult or not? I know week four is more gruelling so am likely to be even more puffed out than now, but should I try it anyway, or keep repeating week 3 til I know I am ready? Sorry for what is probably a basic question but I don't want to be disappointed with myself. I need to complete this programme.... this is the third time I have attempted it, having given up twice before (whilst getting to week 6 and running for 20 minutes non stop) because of a number of stupid excuses. This time I am determined to complete it.
