Versa 2 isn't tracking my distance accurately

[Lburns]

I ran a 10k (6.2miles) race today but my Fitbit logged it as 6.62 miles whilst everyone else’s was showing there about a the 6.21miles.

This happens all the time when I run races and when I ran a half marathon it showed I ran a further 2 miles!

it really has annoyed me today so if anyone can help me to understand why it does this I would be grateful! Thanks

Hi there, @Lburns. Thanks for stopping by in the Fitbit Community Forums and sharing the details about the issue with your Versa 2. I understand how you must be feeling. 

As a first approach, I would like to clarify that it's normal that you see a difference when you are comparing your data with another person, this is because Fitbit devices record your data based on your personal information (age, gender, weight and height). 

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?
