Sync Error Pool swim

garmin connect doesn´t show me the resumen and result of the pool swim activities,

Have you tried a manual upload of the activity to Garmin Connect Web? - How Do I Manually Upload an Activity I Recorded to Garmin Connect?

If you get any message other than Import Complete, then there is a problem with the file. Attach it to this thread. We can take a look to see if it is repairable.

• Zip the file, then in a reply post Insert >> Image/video/file >> click Upload >> browse for file >> OK.
• Or upload the fit file to a reputable file sharing service, such as OneDrive, Google Drive, Dropbox, make the file public, then paste a link to the file in your post.
• Or if you'd rather your activity remained private, you can send me a private message.

Removed erroneous timestamp data using Fit File Repair Tool

Some suggestions to help minimize the occurrence of corrupt fit files:

• Sync your device then remove all activity fit files from your Garmin device using these directions - Removing Recorded Activities on a Garmin Fitness Device 
• Check for firmware updates using Garmin Express
• If issues persist, contact Garmin Support

1910840 it appears that your HRM caused the issue - HRM-Pro, Pro Plus, Tri, and Swim will sometimes corrupt activity fit files 

• Use the HRM download feature only after an activity where it was not possible to wear the watch
• Update the HRM firmware Updating Software on the HRM-Pro/Pro Plus
• During the HRM-Pro download process keep the strap and watch in close proximity
• If issues persist even after the firmware update, contact Garmin Support
• More here about corrupted HR data: Corrupt FIT File Repair Requests

why this happen ?

thank you so much, it worked!
