In terms of distance I can walk, I am sort of stuck. Yes, I can walk a bit further when not warmed up; walking the 0.3 miles from my car to the stadium no longer scares me and isn’t painful.
But still, today, I started to feel “micro symptoms” at about 0.6, honest symptoms at 1.2-1.3 and mild pain at 1.5; had to tighten the abs and focus to finish. I was uncomfortable. And I had a brief “stretch with the clock running” at about 1.4.
Part of the reason I went as far as I did was that there was a slow 13:30 or so runner to chase.

I had limited my pre PT to see if it helped. And yes, the first .5-.8 mile felt fantastic. But as usual, the blood goes to the spine and…that sort of ends it.
The swim: went ok. Ok, it went great; very encouraging.
