Today, I went for a 7 kilometer run on a course with an established distance. I set the MapMyRun app on my iPhone and the Activity App on my watch to record the run. MapMyRun recorded the distance accurately, but the Activity App was off on the distance by 500 meters.
Why is the Apple Watch's Activity App's distance incorrect by 500 meters on a 7 kilometer run?
Specs:
- iPhone 6, iOS 8.4 (12H143)
- Apple Watch, Watch OS 1.0.1 (12S632)
