Fit file message number 79, 140 and 147 gone, and many message number 18,19 and 20 fields gone. ---

assume 1 file saves 50kB The API sends out say, 1 million per day = 50MB Doesn’t seems like much savings ---

I don’t think they’re doing it for the bandwidth saving reasons. If Garmin intentionally removes those fields - they remove “their”, or proprietary calculated fields and leave access only to “your” data (HR, GPS, Pace, Power). Basically you get access only to what you’ve uploaded to Garmin. ---

I agree. It seems more likely to be about directing user traffic than about saving bandwidth on responses to API calls. Users will go to Garmin Connect to the extent that it presents information that they can’t see anywhere else. ---

That would be somewhat understandable if not for how limited connect is. Rounding, lack of custom charts and tables… A lot not within control of the user. ---

> [@kvj](#): > > If Garmin intentionally removes those fields - they remove “their”, or proprietary calculated fields and leave access only to “your” data (HR, GPS, Pace, Power). Basically you get access only to what you’ve uploaded to Garmin. Just adding to this—message 147 is a clear example. Garmin isn’t just removing proprietary fields. They’re stripping out user administered sensor settings like: ``` Sensor name Crank length Wheel size Footpod Calibration factor "Use for speed/distance" toggle ``` These aren’t Garmin-calculated metrics—they’re settings users configured to ensure accurate data. Without them, we lose critical context for interpreting power, torque, speed, and distance. ---

Not sure if anything changed in the Garmin API, but I just came back from a run and I see a VO2max value populated now 👍 ---

VO2 max can be present in the FIT file or sent via the API ---

Right, but I never download the fit files manually. I use automatic sync from Garmin to intervals. Also, I had the same issue as reported above from March 10th to March 17th inclusive. No VO2max value for these dates. I run everyday, and today was the first day the VO2max value is back. ![Screenshot_20260318-211553](https://forum.intervals.icu/uploads/default/original/3X/3/6/36988f8ddbc22ba63021dd4372b9ab052d70a16c.png) ---

The change was rolled back last night, while they take a deeper look at things. Behind the scenes, I’m continueing to push that the original FIT file is what’s sent. Never a special variant of it. To me, it’s the cornerstone of what Garmin initially promised at decade+ ago when sync first started happening. ---

Hey Ray, It’s great to see you looking into this — thanks for the update, and welcome to the board! 😉 I really hope Garmin will continue to make all of the data available in the long term, since it’s the foundation of what has grown into a pretty large ecosystem by now. Thanks again, best regards from Tyrol, Andreas ---

To confirm coming the fields are coming through fine for me from my run at lunch time today. Thanks to our new celebrity member for any advocating done on our behalf! ---

Hi. I was having the same issue yesterday. My rides are ok in Garmin, but here, I am missing a lot of dats. Generated the FIT file from Garmin and imported manually here, same. I will have a look today after my ride if this is still ongoing Any news on that matter?
