Shakedown cruise
(Cross-posted to healthy_fen)
So that's what it needed! Went back to Sports Basement this morning and got a pair of Superfeet green arch supports. (I had a pair, but could only find one this morning, and in any case it was cut down to size 10. I'm an 11 these days. 7pm found it! In the trash, of course; I've been trying to clean the bedroom, too.)
Since I didn't quite trust the arch supports not to start hurting, I came back home, put on the heart-rate monitor, and set out to go around the Rose Garden. No weights, but I kept up the arm-pumping. My heart rate was in the low 120's when I got to the Rose Garden about 17 minutes into the walk. By the time I'd gone around once I'd gotten it up to the mid-to-high 120's. Went around twice more; rate between 125-135. Slowed down to roughly my old pace about 25 minutes minutes after reaching the Rose Garden. Took a couple of pictures, and came home.
The fact that one can walk all around the Rose Garden on grass undoubtedly helped, but so did the shoes (good stiff instep) and arch supports. My shins do not hurt, though they seemed to be getting close to it a couple of times.
The handy chart in the heart-rate monitor's instruction booklet lists "moderate" exercise for my age (60) as 112-128 bpm, so it looks as though I'm actually right about where I should be. I'll be getting at least one more pair of arch supports, for the hiking boots.
