I am using a Forerunner 35.
This morning I ran just over 21km. My longest run in over a year, but not by much (I've done a few 15-16km runs), though there shouldn't be a memory issue on the watch.
The run wouldn't sync to Garmin Connect on my phone like it normally does.
Tried connecting to my laptop and importing via the web, but kept receiving the "One of your files was not accepted by the system. Please contact Support for assistance." message.
Then tried uploading and the FIT file to fitfiletools.com and using the Section Remover tool, as advised on these forums to people with similar issues.
I can see on the map that approximately the last 4km is missing from the run (it should start and finish at the same location, the saved activity on my watch is 1:55:18 & 21.18 km).
Saving the new FIT file and trying to upload that via the web still gives me the same error message.
Have attached the original zipped FIT file. Hoping someone will be able to help?
Thank you.[solved]
