Insensitive

Used my new armband to hold my Nano and Nike+ sensor while running on the treadmill at the DT gym. I set it up for a timed workout: 30 minutes. Being a bit uncoordinated, I wasn't really able to look at it while I was running. It kept telling me "Activity stopped.... please press the center button to continue your workout." So I'd press it, and it would restart. It was clearly keeping the normal time (or at least close to the time on the treadmill), and telling me when I was halfway done, when I had 10 minutes left, etc. But I had to keep pressing the center button.

At first I thought that maybe having the armband on my right arm and the sensor on my left foot was a problem. (Though I know that's meant to be the preferred set-up.) Then I moved the sensor to the tray on the treadmill. Nope, still stopped. Then I moved it to my left arm. Again, it stopped. 

Today I decided to do an interval workout -- which took a while for me to set up, because I kept putting in the paces incorrectly. Luckily, it was designed so that you could adjust the speed and elevation for both the fast and the slow sections, and it would remember the setting for the next interval. I didn't go particularly fast -- 4.5 mph "rests" and a 1.5% elevation and 6.5 mph "fasts" at a 1.0% elevation... raising my speed by .1 mph on each fast interval. Each interval was 2 minutes long, giving me a 30-minute workout + a 3-minute cooldown.

How fast was my average? How far does Nike+ think I've gone? Don't know. Clearly the sensor wasn't registering at all during my run. Boo. Must sort that out soon.

I don't feel tired; I have run a straight 30 minutes at a 6.5 mph pace before. So I think in the future I need to run faster "rests" and faster "fasts". 

Tomorrow is a rest day...
