The Polar Vantage series, Grit x, and Pacer series are great watches. When paired with Stryd, Stryd will provide pace, distance and cadence info to the watch.
The Polar Vantage has autocalibration enabled by default. Autocalibration may work well in some circumstances, but it relies on GPS reception and the calibration factor can continuously change. It is recommended to disable autocalibration.
If you wish to finetune pace and distance as provided by Stryd, you can set a manual calibration factor.
The calibration process is sport profile-specific. When running with different sport-profiles (e.g. road, trail, treadmill), each of them requires calibration to be changed.
- Browse to the running sport profile you want to use.
- Wait for your Polar watch to find Stryd (the foot pod icon will be solid and your Stryd will briefly flash once).
- Press LIGHT to enter the Quick menu and choose Calibrate stride sensor > Calibration factor.
- Set the calibration factor and press OK. Calibrated. Calibration factor: X.XXX is shown. Unless you have run a known distance, set this factor to 1.000 (which means that Stryd pace and distance are changed)
