Versa Lite is not tracking my distance accurately

[Corinac]

Don't think my versa lite is tracking my walks properly. Usely I get 6 miles in a hour and half with around 11,254 steps. Keeping a  pace of minutes around the track.  It's showing 4.02 miles with 10,789 steps still keep 3 minutes around the track.

Hi there, @Corinac. Welcome to the Community Forums. Thanks for sharing the details about the issue with your Versa Lite. 

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?
