I completed my first ever ultramarathon on Saturday and recorded the full thing on my watch with a HRM pro plus on.
The watch took a long time to complete its sync the next day (several hours), which I put down to the length of the activity (16hrs).
However, it is not appearing in my Garmin Connect following sync. I tried to upload the file manually on connect.garmin.com but that also failed, giving "We don't support the file type you tried to import." I assume it is corrupted.
I then tried downloading, installing, and running it through Fit File Fixer, but that gives several overflow errors and then two incorrect call errors when I try to import the file.
I've (hopefully) attached the fit file as a zip below - is there anything anyone more experienced than me can do to help uncorrupt my file? I'd be really sad to lose the record given the length of time I was out for!
If I've not attached it correctly then a 'dummies guide' would be appreciated.
