High Aerobic Load not increasing at all. Perpetual bogus "High Aerobic Shortage"!

A couple of thoughts on this having tracked this data for several years now. To get the high aerobic befit, you need to do Z3/Z4 efforts in a workout that are sustained. One 5 minute effort may not meet the threshold, but 3 or 4 could, or a single 30 minute effort. The key is not that the ride has a series of peaks that each last 1-2 minutes but spaced far apart, but that it is a focused part of the workout. Likely MTB rides won’t do it (at least none have for me). Road and Gravel rides where you can do sustained efforts is always where I see this number go up.

I'm sorry Dachs6 but you are wrong. This High aerobic Load not increasing is a known P1 bug in the Edge1030Plus i.c.w. major bugs in Garmin Express and Garmin Connect.

Last year from June until October/November this very annoying unacceptable bug was in the SW for 5 Months before it got finally fixed.

This also happened on other Garmin Devices like the 530 and 1030 which you can easily see in the many messages on this forum. Only a very short time ago Garmin has brought live old SW versions with these unacceptable failures.

For the Garmin Edge1030Plus it was ok from November 2021 until the beginning of April 2022. From then on Anaerobic Load adds up, Low Aerobic adds up but NO High Aerobic again :-(  :-(

Garmin screwed up again.

Confimring that it is STILL broken.  You can see this workout has vast majority of minutes in Power Zone 4 and 5 with very few minutes in lower zones. Not only did it get labeled as base but no gains were seen in high aerobic. So is there a solution? Are there beta code w/ a fix?  Do need to get a different device?

Hi BRGATESJR,

what's noticable is that there is a lot of time spent in the Aerobic HR-zone and little time in the Threshold HR zone. It is worth checking if the HR zones are still the right ones for you w.r.t. the power zones. The HR-zones changed completely unexpected sometimes in my Edge1030Plus due to a 'forced' SW change.

Still the High Aerobic should be more than zero considering the excercise you did.

If you go to the 'homepage' of your Garmin Device in this forum then most of the time you can find at the top of all posts (or at least at the 1st page) if there is a beta-version available for your device..

What also helps is if you post an issue of which you are pretty sure it's a bug, use the Tag option at the bottom of the page and put in the tags like 'error', 'bug' as much and as many as possible. The chances of Garmin picking it up are then a little bit bigger than zero.

Both posting the issue on the page of the device and on the forum pages of Garmin Express and Garmin connect app may help because if the SW issue is e.g. also in Garmin express and/or Garmin Connect but not reported there as bug/error, Garmin doesn't pick it up

Hi there. I started having the same issue on my Edge 1030 plus. Keeps giving me high aerobic shortage even though I am doing allot of high intensity workouts. Please let me know if you discover a fix? I’ll do the same

What I have discovered is this: unless a ride is labeled “Tempo” or “Threshold” you get ZERO Load added to High Aerobic. Which is ridiculous because Low Aerobic and Anaerobic will both increment on every ride type. This is just plain WRONG!!! 

Hi there fellow cyclist. Bad news for you (and for all the ohter users inc myself) There is no fix for this issue.

Garmin has set live faulty SW releases again. I expect it's not device specific because people with other devices than the Edge 1030 (plus) are experiencing the same very annoying issue as well (again).

I think it's a combi of the SW now live for Garmin Express (I use windows) and the underlying SW at Garmin side which should take care for properly calculating all these values and getting the right settings of your device linked to the calculations etc. The so-called Back End Databases of Garmin.

I suspect this because also the synchronisation of the data on the device to Garmin Connect via WiFi doesn't work anymore again. These two bl**d* annoying issues came together last year as well. Then the faulty High Aerobic issuie lasted for 5 f*ck*ng months before Garmin finally fixed it

It's disappointing but Garmin's SW and FW quality and version maintenance of it is absolutely appalling

What you might do is raise this issue also in Garmin Connect and Garmin Express on this forum and please do not forget to tag it with Error, Bug etc at the bottom of the form. Maybe someone at Garmin is willing to solve these issues soon

That's indeed part of the big error. I discoverd this last year as well when that faulty version was live.

It is indeed wrong because if you do a 'basic' training with long blocks of High Aerobic, e.g. I did a 40 minutes climb  all in Z3 and Z4 in a 4 hour ride, it still add zero but at the same time adds some points to Anaerobic! It's really totally ridiculous because I have never been anywhere near anaerobic.

I have tested this on the 1030, 130, and 945. All the same results. I think the load is calculated on the backend. That said, a right MUST be labeled “Tempo” or “Threshold” to get any High Aerobic load added. One trick I found was to end a mountain bike ride which is the only kind of riding I do…just after completing a long climb. This is more likely to get labeled Temp because you have more time in the higher power zones before the decent happens. Then the decent gets labeled “Base” or “Recovery”. This can trick the algorithm to give you High Aerobic load. I gave up doing this because after a few tests because it completely messes up many Strava Segments and also totally skews the average rides per week. Basically, now I just ignore load. Pretty lame considering I am all in on the Garmin ecosystem with multiple products and years of training data. 

You may believe I am wrong…but I watch this and use it (along with Training Peaks) to adapt my planned workouts when I have shortages or get out of balance. It is indeed more difficult tot get the high aerobic number to climb. But, I can make it climb…in fact I did yesterday on FW 13.40. It is not broken. It is based on the ride itself. Sometimes we like to believe we did a certain effort, but the data doesn’t lie. As I stated above, to get credit for a high aerobic effort, you need to perform one, and I’m sure you are aware that it is much harder than a short HIIT efforts (sprints in the anaerobic range) or a LSD (long “slow" distance) endurance or recovery effort.
