Does anyone have any idea if data can be recovered (mostly interested in GPS-data lat lon)?

Files recovered from unit: drive.google.com/.../1-_F5nwYrfZRa-8yam3va62i20szjQy28

Hey, thank you for quick response! It was a kayak-trip lasting for around 3 hours. During rescue-practise (under water) the trip was perhaps discarded accidently or somehow ended, exact reason unkown. The watch still worked fine, but it was as if I never recorded at all. Files were recovered using Recuva, sorting by files "Last Modified" on the date today. The "ACTIVITY" folder in the file explorer was empty..

Thank you so much, the data quality looks totally perfect! Fit File Tools is definetley something I will checkout (I only found Garmin online fit repair tool so far). Did you also use this tool to remove non activity data? As the .fit format is binary I find it hard to "hack".

not me

search corrupted parts with FitSDK
remove them with hex-editor
use Fit File Tools to repair the summary data structure at the end of the file

you could use Fit File Repair Tool, the crème de la crème, it needs a license for full repair
