Ran 4.0 miles @ 8:09/mile pace.
AHR = 150
Mid 20s, sunny.
First, the bad: The first three miles of this run, the left knee was still barking. I was going slow, concentrating on keeping my HR below 150. There would be the occasional twinge of pain that feels like a sprain. I could still run on it, but began wondering if I was limping in the slightest. It was distracting, and I began to seriously wonder how it'd affect me on Sunday.
But then (the good)...: Perhaps out of aggravation, I decided to test the knee and pick up the pace on the last mile (7:13/HR=162). I really felt it was important to give it a try and see what would happen. Practically no pain whatsoever. The only thing I felt was just a light touch of tightness that was barely noticeable. My stride felt smooth and natural. How'd that happen? Whatever, I'll take it. My spirits were lifted and I felt I could keep it up for another 25.2, but we'll save that for Sunday.
I'm heading down to the Cape tonight. Very fortunately, the weather forecast looks very favorable. Highs that day in the upper 30s, not too windy, and sunny.
