Calibrate Your Apple Watch with GPS

Apple recommends that you calibrate your Apple Watch — which will increase the accuracy of your distance, pace and calorie measurements. It’s actually pretty simple to do so, but it requires that you walk or run at a normal pace for about 20 minutes.

  1. Just go to a flat, outdoor area with good GPS reception and clear skies.
  2. Then, open up the Workout app and select Outdoor Walk or Outdoor Run.

If you have an Apple Watch Series 2 or later, you won’t need to bring your iPhone. The Apple Watch Series 1 and earlier does require having your iPhone nearby for GPS data.
