Left / Right Power in TR Performance Analytics?

We totally do think it matters! There are no ‘bad’ ideas when it comes to feature requests, truly.
To speak better to features like this getting on the roadmap, it’s not that the team doesn’t these features that seem ‘easier’ aren’t important or useful, we just have to prioritize updates that are the most effective at helping the greatest number of athletes possible get faster in the immediate future (such as incorporating unstructured rides into Adaptive Training, and refining Adaptive Training as a whole).

I’ll reiterate this request to the team for consideration. :+1:

Currently amused that we have 2 threads right now with one demanding that more data be recorded and it not being recorded is ruining the experience… while another thread is demanding that TR strip data and them not stripping it is ruining the experience.

Seems like some sort of way for an end user to select the data being output is needed. Maybe in devices you can click on your smart trainer and enable/disable speed output. Or in your power meter when you go into calibrate you can select if you want l/r or not.

This in spades.

Yes. FWIW if you upload a Garmin ride to TR, then download the TR version, the TR version is missing data.

Ouch, this is so much worse that just not recording data - they are actively removing data (aka corrupting the files), and making their service completely unsuitable as the place to store/archive your workout data.

IMHO TrainingPeaks free account is great for archiving. Taking a quick look on my computer I see old Runkeeper files, CycleMeter files, etc. All archived in original format, and easy to download a year at a time.

Yup, I have started syncing everything to trainingpeaks as well now. I need to got through and make sure I have all my historical stuff in one place, and hopefully avoid duplicates.

Yeah, completely agree. I hadn’t been paying attention to my L/R balance then realized I was 60/40 for most of my rides. I’ve been actively working on it on the trainer indoors (much easier than outdoors), and it definitely requires careful attention as in my case my ability to stay near 50/50 L/R balance is very dependent on cadence, total power, seated vs standing, and how warmed up I am (I find it gets better after 10-20 minutes of riding).

Thank you Ivy, it is much appreciated.

@mrtopher1980 maybe I missed it – who is demanding that TR strip data?

I guess if it is going from the Garmin device first to Garmin Connect then at least it will be preserved in it’s original format on Connect. I took a look at my workout from yesterday and downloaded the original from Garmin Connect and also from Training Peaks. Garmin puts it in a zip file, Training Peaks puts it in a .gz file, but once you extract the contents, they are bitwise identical files. The filename does get changed but the SHA256 is the same. However, I’m guessing that this could change at some point so probably the safest place to store it would be on Connect or your own backup of what is on Connect, even though that might not be super convenient.

I’m going to try the Outside workout hack suggested by @kevistraining and will see what TR does to the workout file once it gets synced from Garmin Connect.

I wrote about some of the missing data in another thread. Toss the files into fitfileviewer.com if you don’t have a preferred way of reviewing.

Digging into this over breakfast for my own interest asI use TR for tracking my fitness/activities.

Same activity file. Same datapoint.

Left: Edge 830 → Garmin Connect → FIT file.
Right: Edge 830 → Garmin Connect → Strava → TP → FIT file.

Strava offers an export original option via https://www.strava.com/activities/xxxxxxxx/export_original so they store the unmodified activity. Does (or should?) TP do the same?

*No idea why HR is in one and not the other… the strap I had wasn’t working so I took it off… that might be the HR of my back pocket :man_shrugging:t2::rofl:

Regarding TR FIT file and missing data vs GC/TP/Strava, I wrote up some notes here:

Hi @kevistraining I tried your suggestion and it works, more or less. The transition between segments on some parts of the workout was automatic (no lap button required). on other parts of the workout, it would send the trainer power to something super low (43W if I recall), and the message would say push the lap button to go to the recovery segment, and when I pushed it, it wouldn’t set the power (140W if I recall). So, thinking I needed to push it again, I did so and it instead transitioned to the next non-recovery segment. After that one I just manually set the power. Definitely not super convenient and it would be nice if there was a setting in Garmin somewhere to disable the need to push the lap button, though understandably you actually do want that functionality when really doing the ride outside. I’m going to poke through the settings and see if I can find anything and maybe give it another try.

Ah yes there are a couple of quirks. One of them is the set power on the recovery intervals on some workouts. For some reason the Garmin reads an interval that would normally be say 100w as a band of 0-100w and sets the trainer level to hallway - so 50w in this case. Like you say - fine for outside but not ideal on the trainer.

Because that is how TrainerRoad outputs the workout file.

Oh yeah it’s definitely TRs fault - like displaying the attained power as an interval average rather than a more useful 3s average.

This annoyance only affects us ERG mode users though :wink:
