Could be that the reason is that I’ve stopped doing this. Or taken a 3-month-break.
The battery on the timer died, too, so even though I have been on a few walk-runs lately, I have no way to measure time run vs. time walked.
Still I feel like posting here that yesterday, I have managed 3 fairly “long” runs (for my standard!), and I ran further than the day before that. I am incredibly slow and my steps are tiny, but still, progress is being made. I feel becoming fitter and losing weight is just one of the benefits.
