Charge 3 map and distance issues

[Rosalynn]

When I'm going for a bike ride, I select 'bike' on my Fitbit Charge 3 and start workout. It will connect to my phone but it doesn't track my route. At the end of my bike ride it told me I went 0.26km when I went 6km+. I'd like to have accurate data for this. I have my phone with me for the bike ride.

Welcome to the Community, @Rosalynn.

Fitbit devices calculate distance based on the device’s accelerometer data and stride length setting.

Default stride length is based on your height and gender. If available, Fitbit devices use GPS data to calculate more precise distances.When you sync your device, our algorithm interprets the data from the device, and you see your distance traveled in the Fitbit app. 

Note that when you track an exercise with GPS, both GPS and accelerometer data are used to calculate the distance shown in the Fitbit app. For more information about accuracy, check the article: How accurate are Fitbit devices?. About the map, are you making sure you are connecting your tracker with your phone's GPS?.

I hope to hear from you soon and let me know how the troubleshoot goes.
