I had a great run yesterday. I ran at about mid-morning (took the day off) and the sun was up, but it was still cold with the temps below 10°F. I wore my Mizuno Wave Universes, which are growing on me.
I started out easy, but even so the first three miles were under 7:30. The next mile included a big hill, but after that I started to fly, with a bunch of miles near or under 7:00. I never felt like I was pushing it except on the hills and near the end.
I looked at my training history and yesterday was a PR for this route. My previous PR was at a pace of 7:21 and that was last August, when I was in peak shape.
