Hi
I use a Enduro 2 and have never had an issue with a corrupt .fit file before. I've attempted to fix it using all the information in the forums however I am unable to use the File Repair Tool as I only use a Mac.
The activity was a 4+ hour trail run and when I attempted to save the activity the watch froze and rebooted itself.
Any help to fix this would be appreciated.
I've attached it as a .zip file.
