Inspire not tracking mileage

[caitlyngio]

My fitbit inspire is not tracking my mileage at all. I went for a run the other day, and ran for about 30 minutes.  My mileage came out to 0. I've checked my stride length, changed it, but it still won't track.

Welcome to the Fitbit Community, @caitlyngio.

Thanks for the details shared in your post and for already trying to resolve the issue. I recommend restarting your device: How do I restart my Fitbit device? Please also confirm that your Inspire is paired to your Fitbit account: tap the Today tab in the Fitbit app, and tap your profile picture. 

Fitbit devices calculate distance by multiplying your walking steps and walking stride length. Similarly, your running steps are multiplied by your running stride length. If you feel that your step count and distance are inaccurate, confirm the following are correct in the Fitbit app:

• Your wrist settings (For more information, see Does the wrist I wear my device on affect accuracy?)
• Your height (For more information, see How do I manage my Fitbit profile?)

For more information on how your device calculates your activity, see How does my Fitbit device calculate my daily activity?

Hope this helps!
