Multisport Activity won't sync

jaehrt

Hi there,

last Sunday I took part in a duathlon competition with a personal best as a result. This is the reason why the following question is important for me (it's not just a problem with an everyday workout...).

At the end of the race I stopped the multisport activity as always and a couple of minutes later I saved it. Having a look at the watch another couple of minutes later I didn't see the normal results screen with all the stats, but the starting screen of the duathlon activity... Something obviously went wrong...

Synchronisation with Garmin Connect Mobile didn't work.

So I tried to sync it via Garmin Express. Didn't work either. 

I tried to manually import the FIT file via browser. Didn't work.

I imported the file in TrainingPeaks. At least some general information (total time, total distance, TSS...) are there so the data seems to be in the file. 

My question is: is there a possible way to repair the obviously corrupt file? 

I attached the file. Maybe there is someone out there who has an idea how to solve this issue.

Thanks a lot in advance,
Gerd

    Fit File Viewer was able to fix the file so Garmin Connect Web would accept it. However, the sessions don't look right for a duathlon activity.

    10 km run, 10 km transition, and a 77 km transition.

    2025…

    You can edit the sessions to have it match reality using the edit feature in Garmin Connect Web. Gear icon » edit » Edit Legs.

    Or if you want to post what the session types, time, and distance should have been, I can try to edit it for you.

    Hi seilogramp,

    Thank you very much for spending your time to help me out with my problem. I really appreciate it!

    You are totally right. The sessions look kind of weird. By looking at the session details, I guess that all data is there but messed up in some kind of way. 

    My official results look like this:

    - 46:11 for 10 km run

    - 1:44 for transition 1

    - 1:37:25 für 60 km bike

    - 2:05 für transition 2

    - 49:06 für 10 km run

    That is 3:16:33 for 80 km (or about 76 - 77 km to be honest because the bike course is only about 56 - 57 km)

    To me it seems that all data points of the activity are saved in the FIT file but the assignment of these points to the different sessions is simply totally wrong. Is there a way to re-assign the original data points to the five sections of a duathlon (run - transition - bike - transition - run) by using the official results written before?

    Or do you have any other idea how to sort this mess out?

    Thanks again and best regards,
    Gerd

    Did you attempt this...

    Yes, I started it and didn't find the opportunity to join legs. The current break-up between transition 1 und transition 2 is in the middle of the bike part. Did I miss anything? 
    And I am a bit confused due to the wrong data. Why is the last part shown with a duration of 3:16 hours whereas the data only shows a duration of 2:2x... 

    At least I didn't find a way to solve the problem in an obvious way...

    Through several editing, dividing, and changing of legs, I was able to do this. So at least it is possible to get it close to the official race results

    Unfortunately, I cannot export this for you as a repaired file, since Garmin exports the original .fit file.

    Good to know that it generally works and bummer that it cannot be exported. 

    I'll try again during the weekend and hope to find a similar result.

    Again, thanks a lot for your support!
