Corrupt fit file

hi, sorry to hear about your mishap

while waiting for the repair report back here :

• the amount of FIT files in the ACTIVITY folder on your FR35
  • (when folder contains many fit files time for a backup/clean operation)
• the amount of FREE memory on your FR35
  • (when low FREE memory, check above and below answer)
• are you a MAC user
  • (empty BIN on device)
• was this activity with a long duration or distance compared to previous activities
  • ( long ones use more memory )
• was this activty with a pause somewhere during the activity

happy & safe sporting

update : wrong answer .... see following posts

this time not the usual fit file errror, now it only had a wrong fit file checkcum

your file can not be structural repaired by Fit File Tools's section remover (without removing)

• try it 

check this file 5710.fitfiletools.zip

Thanks - but when I do this it shows a massive time jump in the middle. Can this be fixed?

must have overlooked that one...I will check

let the feedback roll in the mean time

Thanks, It looks fine when I look at it using the fitfiletool, but as soon as it uploads to strava, that's when the pace jump shows up.

Sorry, can not help you with Strava.

Can you see this on Garmin Connect Web ?

At what time and distance does this start.

found it with help of Fit File Repair Tool

It works on Garmin Connect Web, but always incorrectly uploads to strava.

What feedback?

Lots of FIT files 

I'm not sure how to check the memory

I use MAC and now have emptied the BIN

Not a longer activity

Yes there was a pause during activity
