TrainerRoad and Garmin - Intensity Minutes

I’m not sure if this is an issue/question for Trainer Road or Garmin. I use Garmin Connect to track a lot of my health stats, particularly Fitness Age. One metric it uses for Fitness Age is Intensity Minutes. From Nov. 30 (when I started TR) through Jan. 17, Intensity Minutes were recorded in Garmin Connect for all of my rides. Beginning Jan. 18 they stopped being recorded. This appears to be throwing off my Fitness Age measurement. Any insight would be appreciated. Thanks, Dave Reynolds

Pretty sure this is a Garmin thing, they’re really weird about how they use data from third-parties sometimes. I would recommend double-recording the workout on your Garmin device and then discarding it at the end. As long as your Garmin is reading your heart rate data directly during the activity, even if you discard it at the end, it will feed into your intensity minutes and other metrics. That’s what I do (for other reasons) and all my metrics are populated in Garmin Connect:

I’m not sure if it’s a change in Zwift, or Garmin, or what, but I never used to get credit for Intensity Minutes on Zwift rides but for the last couple of months I am now. I am using the Garmin HRM Pro HR strap, not sure if that helps but I have been using that for a couple years now and it just recently started counting intensity minutes in Garmin.

Thanks for the response. So in Garmin Connect, do you save the Garmin recorded rides then delete the Trainer Road recording? I have been running my Garmin for all my rides, but don’t save the Garmin recordings. Trainer Road saves automatically to Garmin Connect. Prior to Jan 17, intensity minutes were recorded, now they’re not. Not sure what changed. Anyway, I may need to start saving my Garmin recordings and deleting Trainer Road rides from my Garmin Connect.

No, other way around. I save the TR (or in my case the Zwift) workout, and then stop the recording on my watch and discard it. If I’m doing an outside ride or run instead of a TR or Zwift workout, I save those, of course.

Okay Thanks. I have been doing the same, discarding the Garmin ride and not saving it, and keeping TR. Something has changed as I haven’t done anything different.

Turns out the issue was with a setting on my Garmin watch. All is well and the sun will come out tomorrow.

@Dave_Reynolds what was the setting? I also track intensity minutes and my TR workouts are giving me very little credit.

I had to go into my Garmin Device settings in Garmin Connect and change the Heart Rate Zone setting to Automatic. My device is a Garmin Forerunner. It is very hard to find. After selecting my device, I selected User Settings; Heart Rate Zones. I hope that helps.

I also have to record my rides with my Garmin, save the ride, and then delete it. Then the Intensity Minutes will show up in my TR rides.

An FYI because i haven’t seen it mentioned here.

The majority of the health settings are actually calculated ON the device you buy, not once the data is uploaded into Garmin Connect. This is partially how they ‘paywall’ certain features on lower tier devices away from those with higher tier ones, even if basically the same data and sensors are present on the device. If you want metrics to be tracked on garmin the work has to be recorded on the garmin device.

I found this out when starting to combine my wahoo and garmin sensors as i use a garmin watch for running but much prefer the wahoo headunits.

I think this is partly a hangup from the fact that Garmin used to licence the algorithms for a lot of these things from Firstbeat and (if I recall correctly) had to pay per user to access these - which was handled by tying the calculation to the device and rolling that cost into the device cost.

Since Garmin acquired firstbeat then this is no longer a concern, but they can’t change the codebase overnight, especially for old devices, so it still works that way. We have seen more things move over to the web based side recently, but as triggerdog says, it’s also a useful way for them to differentiate devices (although they can also lock out sections of the app based on what device you have too)

FWIW: Checking my GC account for last winter when I did not use a Garmin device while doing TR workouts, I got intensity minutes for about 1/2 of the TR workouts. No idea why some got credit and others didn’t. I see no diff based on IF. TSS, HR… This winter I’ve been using my Garmin watch for HR during TR workouts and have gotten intensity minutes for all TR workouts so far.
