My fitbit charge 2 is not calculating my runs properly. I did a 3 mile run and its calculated it at 3 miles and then today its calculated it at 2.3 me and my friend both ran the same route and the same time and hers said 2.8 and mine was 1.8mile . Anybody know why ? It's only recently started doing it.?

Hi @Lucylewis93, welcome to the Community Forums!

 

I appreciate the information and details that were shared in your post. To better assist you with this, can you please let me know if you're tracking your exercise using the auto-recognition SmartTrack feature or are you using the exercise shortcuts directly from your device?  When was the first time you experienced this situation and how many times since then? This occurs with every activity or just with run? Are you using GPS to route the exercise? 

 

Let me share with you that 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. If your Fitbit device uses GPS and you track 1 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.

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.

 

Keep me posted and let me know if you have any additional questions.
