I've been wearing the Apple watch for about a month now and I've noticed that's not always the most accurate when running or even walking for that matter with results sometimes being off by as much as 10% but there is a way to calibrate it which will help improve the accuracy of the distance and pace measurements when running outdoors without your phone or when your phone's GPS signal isn't available such as when running or walking on a treadmill I found that when calibrated correctly the accuracy results were spot-on with an error rating of less than 1% before we begin make sure the location services are enabled on your iPhone to check this head to settings click privacy and select location services you will also want your motion calibration and distance settings to be enabled this can be done from your iPhone by heading to settings selecting privacy qualify location services and selecting system services at the bottom of the page now let's get started on a day with clear skies head to an outdoor location that has good GPS reception such as a park calibration is performed automatically whenever you use your Apple watch's outdoor walk or outdoor run features in the workout app so from your Apple watch tap the digital crown select workout app and choose outdoor walk or outdoor run select the open noble option and start your activity Apple recommends you walk or run at your normal pace for roughly 20 minutes after that simply end and save your workout it's as easy as that now for people who frequently walk or run at different speeds it's recommend that you calibrate the watch for each pace the more you calibrate the accelerometer to learn your stride length the more accurate the Apple watch will be but be warned calibration data isn't backed up on your iPhone and is instead stored locally on the Apple watch the data will be erased if you ever unpair the watch with your iPhone and you will be required to recalibrate it for more tips and tricks like this one be sure to check out how to cnet.com you can also reach out to me on Twitter with any questions or comments I'm dan Graziano for CNET thanks for watching you
