I did week 1, then week 1, then week 2 then tried week 3 and went back to 2, then did week 2, and today finished week 1 again. So that's a total of 6 weeks to date - and I'll be starting week 2 again on Monday.
I'm at the point where most of the time I can run for a full minute and, if it's not up hill and I'm having a good day, I can run for a minute and a half.
An important note if you are keeping track of your runs: When you do a day or week over, it erases what you've done, so you might want to write down your runs (dates, times, and distances) on paper or in a program like Fitbit or Google Fit, etc.
