Ran 10.04 in 1:05:50 in the morning at a steady pace. HR fluctated between 133 and 139 once I got going, while the pace fluctated between 6:40 and 6:20.
Saw Dr. Jex. He had my the X-Ray of my lower back in a sitting neutral position. The L1-L5 angle has changed from -5 to 5 degrees over the period of 4 months. However, the ideal angle, according to the Pettibon system is 35-45 degrees. Interestingly enough, I get fairly close when standing up, but something is out of whack when sitting down. I suspect running falls somewhere in between. I tried feeling my lower back with my hand when running, and it felt closer to the sitting position than to running.
Ran with the kids in the afternoon. Added a little bit of a run from the car to Home Depot on the way to Dr. Jex's.
