Hi all. I have a Garmin Forerunner 955 with software version 26.08. It is calculating my distance incorrectly. I recently did a 10kkm race and i calculated 11,56km. Today I did a 12km route (confirmed on plotaroute.com) and my watch shows 13.81km. Please advise what could be wrong. For Satellites it is on All + Multi-Band. For the 10km race it was on version 23.20 so doubt it is software version related.
