Easy run with Ted at 4:45 AM. Met him on the trail. He started from BYU. After my lips got used to the cold, I could finally carry a conversation. That made the run less tedious for me. Ted told me about the red necks in Alabama that drive as if they were trying to hit you, see how close they can get, and then swerve at the last moment. Saw another runner on the trail later, I believe it is the second one I've seen on those runs. This was after my turnaround, so Ted missed her, but he had a good chance of spotting the rare creatures near BYU. Weighed myself with clothes I've been running in - 155lb. Then changed to summer running clothes - 151lb. So 4lb difference. According to the Daniels Running Formula Vdot tables, this should translate to about 5-7 seconds per mile loss just from the weight. There is probably also a movement restriction factor involved. With the cold temperatures, and the snow on the ground you lose some more. Plus being asleep at the early hour. So struggling with 6:00 pace over 2.5 miles perhaps is not that bad in those conditions. Curt Catmul came by and brought me a pulley contraption to simulate the cross-country skiing movement of the back, and do other stretching and strengthening exercises. I tried it and liked it so far. I am still doing Pettibon exercises and treatment, but I am starting to suspect I've reached the limit of the method for my problem. The last X-ray showed no improvement compared to the previous test - 20 degree angle (decrease from 23, ideal 45), and the unchanged head forward tilt of 8mm (ideal 0). So I improved very fast from the start, but have now plateaued. This is not to say that eventually it could not work, but something needs to be done differently. Ran with the kids in the afternoon. They are starting to get used to the inversion.
