Every day for the past week (starting on Friday Feb 27), I ran 9.2 miles on the treadmill. I usually started out at 7.5 mph for a short .75 mile warmup. Then I would increase the speed to 8 mph or above. Every day except one, I managed to run slightly more than 8 miles in the first hour (including the warmup). A few days I ran over 8.2, which is pretty good for me. At no time did I ever reduce my speed during the first hour.
At the end of the hour, the treadmill would reset and I would continue at a slower pace -usually 7.0-7.5 for 10-15 minutes.
As a rule I lost slightly more than 2 pounds in fluid each and every time. The room temperature was a balmy 72-74, but I did use a fan to cool off.
I suffered no injuries, although once my left knee did act up a bit, and a few days later I had a diffuse ache in the other knee at night. I did develop a rather big blood-filled blister on my left little toe and some other smaller ones on other toes on my left foot. I also suffered a rubbing spot on my left ankle over the Achilles. Nothing major really.
I hope this will put me on a good base for the upcoming Boston marathon.
