I combined my two activities using the Fit File Tools but I cant upload them, anyone know why? New to running and did my longest run this morning so wanted to have it recorded accurately. I paused at run at some lights but accidentally saved it halfway through.

Did you delete the original activities first? I think Connect will detect the merged activity and the first original activity as duplicates, since they should have the exact same start time, and reject the merged activity on that basis.

Your file didn't work for me either. Error states, "An error occurred with your upload. Please try again." Fit File Tools is not always successful at merging activities.

You can try this - 2025-10-19-11-00-02-fixed.fit, which is a 10 km run.

If you get the message "This file has already been uploaded," you'll need to delete the original activity that started at the same time, as flowstate mentioned.

Thank you, looks like that file worked. Must be issues with data in the Fit File merge . Thank you anyway!
