Ha! Did not let the earbud-search panic keep me from continuing into W4! Put on a Guardians of the Galaxy playlist (only on one ear, hence earbud panic), and off I went.
Ankles fine, calves surprisingly good although I can feel a distant shimmer of a pain (which disappears with post-run stretching), back really surprisingly good. I used to not be able to walk more than 20 minutes without getting backache, and now I am managing to run for 16 not even noticing my back!!!
5 min runs were ok even though the hill that left me gasping in week 1 was in the middle of it!
It feels like this program really works!!!
Thanks C25k!!!!
