Versa 2 is tracking my distance inaccurately

[SARAHANNE2]

The mileage on my versa 2 is all over the place. I walk the same walk every night and one night it’s a 3.5 mile walk, the next night only 3 miles. On my bike, one minute I had ridden 4 miles and two minutes later I had ridden 10 miles. By the end of my normal. 11 mile ride, my watch said I’d ridden 20 miles. I’m fast, but not that fast. I’m getting very frustrated as without the tracking ability it becomes kind of useless …

Hi there, @SARAHANNE2. Welcome to the Community Forums. Thanks for sharing the details about the issue with your Versa 2. I understand why you're feeling frustrated. 

Fitbit devices use the formula below to calculate distance. Your stride length is determined by your height and sex. Steps x Stride Length = Distance Traveled

Please note when you track an activity with GPS, your device calculates your distance using GPS data rather than steps. If you begin moving before you get a GPS signal, your device calculates distance using your steps until GPS connects.

To update your stride length, track a run with GPS or measure your stride length manually. For more information, see: Can I change my stride length in my Fitbit account?
