Charge 5 distance not matching

[Natric22]

I ran a half marathon 2 weeks ago. The route was 14.1 miles, I tracked it with my car when I looked at the route prior to the race. according to my Fitbit I ran over 16 miles. At the 6 mile mark of the ran it was showing I ran seven.  Can someone help me understand why this is happening?

Also, is there a way to at tracking of stair climbing?

Thanks for any help!

Hi @Natric22. Welcome to the community forums.

Thank you for providing the details regarding this situation with distance.

Please confirm that the following are set correctly 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?)

Fitbit devices calculate distance by multiplying your walking steps by your walking stride length and multiplying your running steps by your running stride length. We estimate your stride lengths using your height and sex. Track one or more runs using on-board or connected GPS, we evaluate that data to automatically update your running stride length. For best results, run at a comfortable pace for at least 10 minutes.

However, if you prefer to measure your walking and running stride lengths yourself and enter them manually, see How do I measure and adjust my stride length?

Note that when you're tracking an activity with GPS, Fitbit calculates your distance using GPS data rather than steps. If you begin moving before you get a GPS signal, the tracker will calculate distance using steps and stride length as described above until a GPS signal is found.

Note that while Charge 5 doesn't track floors, it has many other features that you can take advantage of, such as the EDA scan app and the vibrant color display, check all of them on the main page.
