Forerunner 945 corrupt running activity

Hi,

I went for a run this morning and after finishing the run it would not sync to Garmin connect. Not over wifi, not directly with the phone and also not with Garmin express. When I tried to upload the fit file from the watch manually to Garmin connect also this failed so my .fit File is corrupt. I just for testing purposes started another running and cycling activity and both sync normally.

Why is my file corrupt and any ideas of how I can fix the corrupt file? I already tried fitfiletools.com but the corrupt time fixer did not help.

Any hints/tips are appreciated.

I used a combination of 2 repair tools. Starting with FitFileTools using the section remover, then running that "repaired" file through Fit File Repair Tool.

This will work - BbbB-fixed.zip

Noted that you used the HRM-Pro which I suspect was the cause of the issue. HRM-Pro, Tri, and Swim will sometimes corrupt activity fit files

Update the HRM firmware How Do I Update the HRM-Pro Software Using the Garmin Connect App?
Note that HR data download after the activity is usually for swimming or when for some reason you could not wear your watch during an activity.
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

Otherwise, here are some suggestions to help minimize the occurrence of corrupt fit files:

Sync your watch then remove all activity fit files from your Garmin device using these directions - Removing Recorded Activities on a Garmin Fitness Device
Regularly check for firmware updates using Garmin Express
Let us know when you encounter corrupted files again

Hey guys,

Thank you very much for your feedback. I have actually been using the "Download HR" Feature after most runs because I assumed the option is there because some data is not transmitted during the activity. Won't be doing that anymore.

I'll go through all of your tips. I always keep the strap and watch up to date but I have never removed recorded actitives.

thanks again
