Distance suddenly doubled

[wizzo68]

The other day my distance went up from 14 miles to 26 miles in the space of a few minutes.

that day I had done 25,000 steps in total, which from my stride length calculation is nearer 15 miles.

I had gone for a 13 miles run in the morning using the surge gps, which was recorded correctly.  Then I did some normal activity and in the evening was done some work, which should have triggered the automatic activity logging after 15 minutes.  However, this automatic activity did not get registered but around the 15 minute mark, my milage on the watch went up from 14 to 26 miles. During this increase, I only had added about another 1 mile walked. 

Has anyone else experianced a sudden increase in their distance?

Hi @wizzo68 it is nice to have you in the Fitbit community with us. It is definitely a weird issue you are experiencing with the sudden increase of distance. In this case I recommend you to perform a restart of your device in order to avoid this kind of behaviour in the future. If you want to delete this information, you can add "Driving" as an activity to remove the increased distance and calories. You can add the activity here. Have you experienced this issue again?

Hope this information helps!
