This was an odd one. In my prior workout, I successfully completed a workout at the week one level with sixty second runs and ninety second walks. I found out this morning that I am not yet ready for the week two level. It was supposed to be very hot today, with temperatures in the mid-nineties. As I type this, it is still 91F. With the predicted temperatures, I decided to do my first week two level workout in the morning instead of the evening. This was bad on several levels. I had only completed one week level workout, not the normal three. I was moving up too quickly. Having a morning workout instead of an evening workout reduced my rest between workouts by twelve hours. The temperature may have be lower in the morning, but not by much and the humidity was much higher. When I got back to the car this morning, the temperature was 85F and humidity was 80%, not a comfortable combination. The combination of factors resulted in me almost completing one week two level ninety second run and starting a couple more. At that point, I realized it wasn’t a good idea and started the cool-down walk on the way back to the car. I still wanted to have a full workout for the day just to keep up regular exercise, but doing it outside wouldn’t work today. On the way home, I stopped at another community recreation center. They have a gym with some treadmills and another track. This track has a slightly different design than the other one. The corners have a diagonal and are less cambered. Though it this one is also above the courts, the railing is solid instead of open. And, with the air conditioner vents staggered around the perimeter, the cool air coming in doesn’t immediately fall to the courts. It was much more comfortable. Best of all, the track was free. After work, I went and tried the track and got a little bit more of a week one level workout in. As I had only been using my VFFs for my workouts and the last workout on a track had hard landings, I decided to try the New Balance 991s that I use to wear. It wasn’t a good idea. I know that heel striking is very bad on knees. I tried to avoid it and use a posture more like I did with the VFFs. It did not work as well as I would have liked. As expected, there was a more cushioned landing, but the heel got in the way. After half a dozen laps, my right calf was tightening up and I was on the way to a limp. I aborted before it got that far. I need to take some time before my next workout to let my calf recover. I also need to try out a good treadmill before I spend the money to upgrade mine. I think the next workout should be week one level on a treadmill in my VFFs. With all of the variety of surfaces, shoes, VFFS without and with socks, I need to get some consistency into my workouts. Perhaps I can do that on the treadmill, or not.
