How to fix the attached corrupted FIT file?

Hi All,

So I ran my first marathon on 19th Jan and I had setup the run workout setting some pace targets for intervals. It worked fine during the run and I saved it post run. But the activity didn't sync to Garmin Connect app. I can see the activity on the watch with only duration and distance but when I click on it, it shows loading and then disappears and doesn't show other stats like pace, HR etc.

I tried to manually import the FIT file which is 1.5mb in size as suggested by customer support but it doesn't work. It either shows that it has already been uploaded whereas there is none or that there are errors. As suggested by customer support further, I tried to search for repair tool online on google but not been able to fix the file.

This data is really important for me for future preparation. Could someone please help me in fixing the file?

Thanks,

Ruchi
