Okay, just to clarify. Instead of doing the set 3 days in week one, you did it 5 days? If that is how you did it, then honestly...I would go to week 2 and drop down to the recommended 3 days a week max until you have compeleted the program. The rest days are there for a reason, and one reason you might feel this way is because you are overwhelmed and burning yourself out.

I personally kept moving forward even when I couldn't complete a run, and finished just fine.

IN GENERAL, I agree with the sentiments of the person who messaged you, but you're an individual and everyone is starting from a different place with different limits.

My thoughts are, if you completed the day then go on. Even if you struggled to complete it. You did it, so go on. If you weren't able to complete it then allow yourself to repeat it. Don't be upset with yourself, just repeat.

It turned out in my case that I didn't repeat any days, except the very first one. In fact on a couple of the days I completed them because I was telling myself that if I stopped and started walking, I'd have to repeat that day. That's what kept me going.

personally I repeated week 2 and 3 just because I felt I was not ready to move on yet. I could not get the breathing down, I could not get comfortable at a pace and I just was not strong enough in willpower to move on.
Then I learned that I needed to slow down, relax and just take it one day at a time. That has really helped me push through. I just this morning finished week 8 day 2 and feel really good. I cant wait to be a graduate!!
Just hang in there, slow down if you need to and breathe.. You can do it!

I agree with others, it depends why you aren't moving on to the next week - if you're just frightened of failing, then you should just bite the bullet and go for it but if its because you haven't been able to complete the level, then that's a bit different (well, in my opinion anyway lol)

Personally I've repeated days (I had a couple of weeks off when I went on holiday and didn't feel ready for the next level without repeating a day of the last one just to check my mojo was in place!) and I intend to repeat W5D3 as I was leaving drag marks on the trail I was dragging my feet for so much of it so didn't get the sense of achievement I wanted when I finished. Like I said, that's me personally but as long as you aren't delaying progress, I'd say repeat if you have to.

Do what works for you. But don't hold back in fear of the next run, the programme really does work. I repeated W6D3 four times because I really struggled with it and thought I wouldn't be ready to move up to running 23mins. I decided I couldn't stick the sight of W6D3 anymore as I continued struggling so just moved on - so glad I did it was so much better. Weird how it works. I could run 23mins fine yet two lots of 10min hurt so bad.
