Fellnr about treadmill computer vs Stryd vs wrist based vs NPE run vs calibrated treadmill accuracy

One of the most accurate treadmill calibrator is fellnr.

What does fellnr write about the accuracy of different sensors in his NPE run review:

  • Well, the sensor (NPE run) is fairly cheap, listing at $99 at the time of writing,
  • and it’s almost certainly vastly more accurate than your treadmill display
  • and more accurate than the accelerometer in your running watch.
  • It’s more accurate than a standard Footpod,
  • and while Stryd is remarkably accurate outdoors, Stryd tends to struggle on a Treadmill due to the speed variations.
  • Runn is also a convenient approach, and if you took the time to calibrate your treadmill, you could add the calibration factor into most running watches.
  • The Runn also measures incline, though I’m not sure what software would support that measurement. I’d love to have incline data from my treadmill runs, but it may require a custom Connect IQ data f

Conclusion of the MRIS

Treadmill speed measured with different methods – a science of it’s own and little is known about it. We miss numerical and statistical data of a high quality treadmill with a high quality treadmill motor measured with high quality open source treadmill speed sensors analysed with contemporary open source data analysis software.
