Garmin failed me for my scientific experiment

Y’all this morning I went back to the treadmill.  Can I just say that currently I am in love with it.  When it comes to 100% humidity and temps in the mid 90’s the treadmill becomes your best friend.  I ran 5 miles at a 1% incline.  The first mile was the slowest at 9:57, the second was 9:31 and then I went down from there and I ran the last mile in 8:40.  I finished in 46:20 with an average pace of 9:16.

Currently I’m sporting this look.

Don’t hate, it took months to nail this style.

I always try to run at a 1% incline or higher to simulate running outside as closely as I can.  In case you’re wondering how the treadmill compares to running outside, here’s a great treadmill pace conversion chart that tells you.

Because I’m a bit analytical and somewhat of a geek, I wanted to find out how accurate the treadmill and the treadmill conversion chart are as compared to my Garmin 620.  The Garmin 620 is supposed to also work with the treadmill and since I’ve never tried it, I decided to test it out on Sunday.

I ran 4 miles and then checked the Garmin…..

garmin fail

And it looked almost like this…..

Except my Garmin said that I ran .33 miles in 39:10 minutes.   POINT 33, Bastard!

So I went to the Garmin website which for some reason always confuses me.  I seem to have more luck in the forums.  Anyway, from what I could surmise, you have to wear the heart rate monitor for the Garmin to work on the treadmill.

Since I haven’t worn the HRM in a while I decided to test it out.  Yesterday when I went for a three mile run in the neighborhood, I wore it.  It still works, and quite well I might add.

So, this morning, I ran those 5 miles on the treadmill with the garmin and the HRM so that I could determine how accurate the treadmill and the pace conversion chart are.  As soon as I finished my run I hit the button to stop the watch and after getting off the treadmill I checked to see what it said.


                            .38 WTF?

So this entire post that was supposed to be a scientific finding based on the measurements of the treadmill versus the pace conversion chart and the measurements of the Garmin  is a total and complete wash!

If anyone has any idea how to make the Garmin 620 work while running on the treadmill please feel free to leave me a comment or email me.

Until then I guess will just have to leave the scientific experiments up to the experts.


How often do you run on the treadmill as compared to outside?
Which do you like better?

  1. We moved from a house that had a perfect running path to a house that doesnt in March. So, since then I’ve been running on a treadmill more than I would like to. I find it incredibly hard to track my running and haven’t been doing a good job at it which bums me out!

  2. Thanks for sharing the link to the treadmill pace conversion. I knew there was a reason my treadmill wasn’t giving me the correct pace.

    I would rather run outside, I find the treadmill boring, but I go to work at 6:00 am so I have to run after work. It’s in the 100’s here, so treadmill it is!

  3. I have a FR220 only (jealous) – but there you have to turn off the GPS to use it on the dreadmill. You do this by pressing on the “up” bottom after unlocking the watch. Let me know if it works 🙂

  4. See I live in Canada. We have llloooonnngggg winters so i look forward to sweating during my runs! Humidity is nothing. I save the treadmil for the winter when I have no choice becasue of the 4 foot walls of snow and ice. I did wonder how well a Garmin would work on the treadmil though…thanks for trying!

    • LOL, the grass is always greener right? I do have mad respect for anyone that runs in the snow though, I don’t think I could ever do it. I’ve got no shame, I’m just a big fat snow wuss. 🙂

  5. That’s interesting. Normally Garmin is really good with that sort of thing. When I went to college in upstate NY, I ran on the treadmill more frequently. Honestly, I don’t mind it too much. Right now I would say I run once per week or so on the mill.
