A Calibration That Actually Worked - RunLog 11-30-15

After calibrating the Garmin's foot pod this morning, I really had to go run on the treadmill to see how close it got. Usually, I have to do it 2-3 times, before I get it into the reasonable category or otherwise known as close-enough.

Also, running in 18*F weather this morning just didn't thrill me all that much and even though it had "warmed" up to 27*F when I left the house, the treadmill was calling.

No, I am not one of those runners who hate the treadmill, I use it as the tool that it is. If I want to run in short and a t-shirt, work up a good sweat, run faster paces and be sure of what I am always stepping - from late-fall to early spring it mean getting on the treadmill. Running outside during that time frame in Maine - well you ain't wearing shorts and t-shirts too often.

Getting back on the treadmill

I wasn't sure what I was going to do, but it wasn't going to be a speed workout!!! I just wanted to get on and get into the zone. So I started out at 8.6 (just under an 8:00 minute pace), I was feeling pretty good and when the treadmill hit 1.01, my watch beeped I had gone a mile.

Holy shit!!!

I have never had a foot pot or GPS device measure a run on the treadmill that close. Usually I can get it down to .02 to .03, but .01...all I can say is WOW! Okay Harold, I was pretty sure that was just an anomaly and wanted to see where it would be at the end.

I don't have a clue what the dips were, but they happened according to the Garmin. To the best of my knowledge I just kept running the entire 4.0 miles without any stops or changing the speeds. I did get into the zone pretty well felt good during the entire run.

When I hit 2.02 and the Garmin beeped 2.0, then 3.03 and the Garmin beeped 3.0 and the best surprise was when the Garmin beeped 4.0 miles, the treadmill still read 4.03. Being off by .03 after 4.0 miles -- well I gotta say that is close-enough.

Now I didn't do anything all that different when I calibrated it this morning, but I did focus more on how I was running. I do run slightly different on the treadmill and I tried to mimick that slight difference while calibrating the Garmin. It worked I guess.

Now, if I can keep this level of accuracy for a bunch more runs, I will be pretty happy. However to be honest, I am not that optimistic that it will remain this good, but it is something to hope for.

  1. Nice! LOL could I mail you my watch and pod? I'm about ready to throw the pod away; it's never even remotely close.

  2. Keep the pod, it has more to do with the watch and how it reads the data. :-)
