A walk that was recording for over 2 hours has now come up with a FIT file that says it is empty
How does that happen?
Anyone any ideas?
Thanks
Is this the error you're seeing when trying a manual upload to Garmin Connect import data page?
3 months ago that was my first marathon data, you don’t understand how devastated I was losing that, so grateful to you for last time.
This times it isn’t so much of a big deal!
I tried to upload via Dropbox but it says
unable to upload, empty files cannot be uploaded
How do I zip it?
Yep, nothing there.

How does that happen?
Did you record the activity normally with a Start, Stop, then Save? Are there any other fit files in the \GARMIN\ACTIVITY folder on your Forerunner 35?
I paused it, and when i went to resume, the watch was at the main screen. Normally when I have left it on pause too long the autosave counts down from 30 seconds but the watch will buzz to notify the countdown but to be honest i don't recall that this happened so maybe just lost the data while it was paused. This has never happened before.
Yes a whole list before and one after
Perhaps you should clear those out of the folder \GARMIN\ACTIVITY.
