It's surprising how fast your body will adapt, but be honest with yourself on your goals. Nothing worse than setting yourself up for failure. Honestly, I needed to do week 1 about three times before I could move on.
Try a goal where you do week 1 and just do the 3rd, 5th, and 8th run. Then the next week try every other run. Perhaps by week 3 you can do them all, but maybe only 6 of 8? Just make a plan and stick to it and trust that your body is made to run.
Remember, you can always run longer if it feels right.
I suggest the book The Courage to Start by John Bingham.
You Can do this in your own way. It's perfectly fine.
