Manual calibration of Indoor Running

Former Member
Former Member over 7 years ago
I’ve just gotten a Forerunner 935 and want to start indoor running on a track at my gym.

The instructions say say that to calibrate I need to go for a few outdoor runs, but it’s 10 plus degrees below freezing in Chicago right now :)

I know the length of the track, is it possible to manually enter/record the distance somehow, or better still calibrate the watch indoors?

Thanks

    it needs to calibrate the accelerometer to get the distance accuracy based on your running. You have to calibrate with GPS. The other option is use a footpod, but those need calibrating as well! Stryd is probably the most accurate uncalibrated footpod but it's expensive

    On your first Treadmill run, you will get a popup asking you to calibrate (at least I did) where you can enter the distance from the Treadmill.
    Later on you can "recalibrate" if you after the run select "Save and calibrate" (or whatever it is called) instead of the normal "Save".
    I use a footpod if there are variations to the above behaviour.

    The internal sensor is 'ok' for giving pace indoor - but not very accurate. I would highly recommend a footpod. I have an Adidas one, and its pretty accurate. They are reasonably cheap and you can calibrate them using a known length run - ideally a track, without running outside or relying on a questionably accurate treadmill readout.

    I have just brought a Garmin Footpod for this reason and it works very well. Yes you can calibrate at the end of the workout but I was fed up with the wrong workout data being synced with Strava. You need to use it outside for a couple of runs and it will auto-calibrate. I did a 10k on the treadmill over the weekend using it and the splits were all the same, as it should be at a constant speed. From what I've heard, many treadmills are not calibrated properly so the footpod may provide more accurate distance and speed data.

    If you know the indoor track length, you can just calibrate it with the indoor tack.
    Though I would not trust 935's internal accelerometer much. I would rather use a footpod or even better a stryd.
    I run indoor track in winter a lot as well, once I calibrated my Stryd, it has been dead on every time when I run indoor. (I calibrated it on a outdoor track though)

    I do lots of training on a treadmill to get enough vertical (it's pretty flat around here..) so I've been thinking about how to get the distance measured automatically. Is the footpod the solution here? Also, what are the differences among the manufacturers/models and what other advantages one might get from footpod? In addition, are there any other solutions for tracking the distance on a treadmill? Thanks for the help! :)

    Just calibrate. The footpod might work but it doesn't work well for most people on the treadmill. Your cadence, ground contact time, etc all change when running on a treadmill vs outside. Use the distance on the treadmill and calibrate.

    Just FYI, I don't own footpod. Im merely thinking if that would be a solution and apparently it is. :) Does anyone know what are the pros and cons of different pods?

    Suggest you take a look at DCRainmaker’s website for a good recap on various foot pods. Fellrnr also has good comparisons and accuracy data.

    Actually there's not that many comparisons but yeah, will do search, thnx!
