Found a fairly tight range for today's 3.5 mile tempo. Target pace was 6:52/mile. I hit it in 6:48 overall. My half mile pace splits are illustrated in the graphic above:

6:41 6:48 6:44 6:48 6:48 6:57 6:55

Yes, I did start out a bit too fast and yes, I was starting to wash out in the end. But in general, this was a good one.
