Decided to keep an eye on the high intensity 3PLUS2 running program from FIRST in "Run Less, Run Faster." Three days of run types, two of cross training. I don't feel I'm ready for it at this time, though.
I think I'm more fit to do the RW beginner 10 week half marathon training plan, maybe adapting in a higher intensity workout from the 3PLUS2 now and then. Yet keeping in mind "feel" training, with a plan to catch me when I'm slacking off.
Continuing confusion on how to proceed when #RunningAgainAtAge80.
FIRST is the Furman Institute of Running and Scientific Training.
