I've been trying to figure out the best definition of one month. It could be 28 days because it is four 7-day weeks. Even though November is 30 days long, it cannot be not 30 days because I started on November 2, i.e. no running on November 1. Today is December 2, Day 31, and I have settled on it as the best marker for one month. I am more than a little surprised that I made it this far, and I am going to enjoy looking back on January 1 to see that I ran every day of a 31-day month.
Again I had to get the run in on the treadmill, but this time it was before 11:00PM. I had all of my stuff packed and stowed in a locker, ready for a run at lunch (intervals, no less), but I needed to finish something that came up at work without warning. It was the right thing to do. I planned on running longer this evening, but thought better of it because I need to start getting more sleep. I did a weight check this morning and I was up a little bit from last time. I am pretty certain that it is from not getting enough sleep.
The 20 minute pre-set workout was good enough. I focused on cadence and posture. I tend to slouch when I run and I need to keep my head up. For this reason, I went with listening to a podcast rather than reading. It worked well. Ironically, I listened to part of The Problem with Treadmilling from Phedippidations. I agree with what Steve presented; there is a certain emptiness when running and there is nothing moving around you - air, light, scenery. That being said, it sounds like his treadmill is loaded with much more gadgetery than mine, which means there are more distractions. The one I run on is older and much less sophisticated: 4 LCD numeric displays, 6 pre-set workouts, no interfaces to any other equipment. Also, being a bit of a data hound, I don't tend to pay attention to the display because I do not trust the accuracy of any of the numbers. I wear a GPS watch set to indoor/treadmill mode and a footpod. It's moderately better, but still far from perfect. As long as the motor is good and it can change the elevation, I see no need for something zippier.
