GPS distance issue on watchOS 27

Ive been running at the same spot few years using garmin and Apple watch. After updating to watchOS 27 I noticed the distance was off around 300-400 meters during my routine 8km run distance. Even the pace is not right because seems to be a little bit fast

Try recalibrating the GPS first:

  1. On your iPhone, go to Settings -> Privacy & Security -> Location Services and make sure it’s ON.
  2. Go to System Services and enable Motion Calibration & Distance.
  3. Take your Watch outside and do a 20-minute Outdoor Run/Walk in an open area, keeping the iPhone with you.
  4. Restart the Watch and test the same route again.

Apple recommends this calibration process to improve distance and pace accuracy.
