What a difference a couple of days make! Today's C25K run/walk was much easier than Tuesday's. Go figure. It was still challenging enough, as I picked up the pace a little, and logged my best average of this C25K (18:18 min/mile). I changed the "trainer's voice" on my C25K app, and I wonder if that helped! This voice is more no-nonsense, get-'er-done about the run/walk commands.
Glad to have it on the books, and glad I'm feeling better.
