Notes
I was trying to do a negative split and really push the last 5k but was too tired by then. My back/neck has been doing pretty well, having this cast. It seems to have possibly modified my form in how I hold my arms for the better, but it may revert when the cast comes off Thursday.
Holding a water bottle in my left kind of balances the cast and arm swing. (I didn't take a drink the first 5 mi.)
I saw 2 rabbits, a dear, and a squirrel playing chicken. The latter just stood right in the middle of the trail, perfectly still. He thought I wouldn't see him, I guess. He let me approach to about a couple yards before he decided better.
