Well, I developed the hip/butt discomfort (slowly) at about 2.5 miles ..and by 3.77 I decided to seek a playground to stretch. Pace had slowed, a lot..walked home then, did a 1 mile “take a break” walk at 16:20.

there were issues; not stretching and perhaps too much last week and perhaps too much sitting.

Comeback programs are rarely monotone; there will be small “learn from this” setbacks from time to time.

Update: I felt tired and I was to test positive for COVID early the next morning. I probably was covid positive when I started this.
