Hi to All Garmin fellows,
On 10th of August I have finished my 1st Iron Man, unfortunately I can not analyze the data, as the fit file is corrupted and I was not able to upload to Connect App.
I also have tried fixing the corrupted file with "Fit File Repair Tool" but I receive the "Overflow" error message.
Could anybody help in solving this problem please?
Thank you for your help in advance 
Peter
Your file can be easily fixed by passing it through the free Section Remover at https://www.fitfiletools.com/ (without actually removing anything), although it looks like it contains only one 227km Run leg, but that can be fixed directly in Garmin Connect, by splitting the activity into several legs, and changing the activity types accordingly:
I also have tried fixing the corrupted file with "Fit File Repair Tool" but I receive the "Overflow" error message.
You'll need a licensed version of the software to avoid these error messages and be able to export a repaired fit file.
This will work - [solved]
Suggestion to help minimize the occurrence of corrupt fit files - Sync your device then remove all activity fit files from your Fenix 6X using these directions - Removing Recorded Activities on a Garmin Fitness Device
And congrats on the performance. 
That really worked, thank you very much!
