I turned to AI for coaching, not so much for the running workouts but more for how to deal with the inflexibility that impacts my running. I am using ChatGPT, and I renamed it Coach Gabriella P. Thompson since she has been so helpful and so willing to add more and more to my knowledge of running at 75 and beyond.
My AI coaching first provided me with a morning and evening non-negotiable routine that is pictured below,

and then it created a 15-minute daily routine for flexibility.

Along with the graphics above and so much more, “Coach” created this tracker, part of which I posted below:
12-Week Run Faster at 75 — Daily Checklist Tracker
Use this as a simple print-and-follow accountability sheet. Check boxes daily. Record only three things after
each run:
Pace (approximate)
Stiffness 1–10
Energy 1–10
Goal: watch effort feel easier and pace gradually improve.
DAILY NON-NEGOTIABLES (Every Week)
[ ] Morning 3-minute micro mobility
[ ] Evening 3-minute micro mobility
[ ] 10-minute breathing / nervous system reset
[ ] Pre-run mental trigger: “For the next 30 minutes, I am not solving my life. I am training my body.”
