Apple Watch not recording accurate distance since latest update

ever since i updated my iphone 14 and apple watch series 9 to latest update, it isn’t recording accurate distance and workout time, specifically when running and walking on a treadmill. Any suggestions?

If a recent update scrambled your stride metrics, clearing the old data forces the watch to relearn your movement patterns:

  • Open the Watch app on your iPhone.
  • Go to the My Watch tab.
  • Tap Privacy, then select Reset Fitness Calibration Data. 


If this is not working you might need to recalibrate your watch

  1. While wearing your Apple Watch, go to a flat, open outdoor area that offers good GPS reception and clear skies.
  2. Open the Workout app, then tap Outdoor Walk or Outdoor Run. To set a goal before starting, tap the More button, then tap the goal button .
  3. Walk or run at your normal pace for about 20 minutes.
