Yeah! The very next day I went out and clobbered my recent speed records, doing my 1.5-mile at a 10:45 pace. Clearly I've crossed some threshold, and a couple of random passersby noticed it a day sooner than I did.

Noticing that prompted me to track down this page in my old on-line journal, where I'd recorded some timed runs from 2003 and 2004:

I'd completely forgotten that there'd been a while there when I could run a mile in 8:34.
