Adaptive Training Closed Beta Update

Not sure if this is the right spot for this. Did my first outside workout ever today and it looks like I failed it as there was no adaptation. Im running a garmin edge 130 plus and I have to use the built in workout screen. It was only my second ride using the 130. Pressed the button at the wrong times I think. Oh well. It looks like I hit all the marks but will try again. I was scared to try them but they are fricking awesome. Love outside workouts.

Thanks Chad!

Interesting you mention power drop outs. I am troubleshooting power dropouts on TrainerRoad. I am using the DC Analyzer Tool to see if its the TR connection or the pedals. It looks like its more on TrainerRoad than my Garmin Head Unit or Zwift (both connected via Ant+).

I’m still figuring out the overlaid data to be sure what I’m seeing. Sorry to get all into an OT discussion here. I have the power drop issue posted on teh Garmin Rally thread as well.


Had a strange behavior today from AT today.

My Day 1 is Sunday so I need to move my workouts back a day to accommodate this since you can’t set day 1 in plan builder. Finished Gold Hill with Moderate difficulty rating. Then went through the process of closing the TR application and launching it again to see if there are any adaptation which there weren’t

Checked in today (Tuesday) to complete my Monday run and there were now adaptations for my rides to be made. This seemed odd so I have not accepted them. I am going to complete my ride tonight and see if that fixes anything.

Just wondering if anyone else has experienced this. It looks like the dreaded Sunday bug has infiltrated AT.

Congrats! I’m an outdoor workout fan too.

So, a few things to confirm:

  • Sounds like you have a TR workout marked outdoor and pushed to your Garmin
  • Are you using Plan Builder? That’s a requirement for adaptations
  • Did you complete a survey? Adaptations require a completed survey
  • Was it a struggle survey? If so, even if you mark it “did not struggle” TR will fail you and therefore no adaptations proposed
  • Do you see a difficulty level vs your current PL for that energy system, and does it show +0.0 or is there a positive number there? The 0.0 indicates no credit for the workout – AT hiccup still being worked.

Timing on when proposed adaptations seem to vary. If the other items seem ok, check again tomorrow and see if anything comes up.

@IvyAudrain It would great to be given feedback on outside workout execution, especially workouts that are given a fail mark. A layer on the power graph showing the target power would go a long way. This is really a learning process for me as well as the Machine :slight_smile:


There is an open feature request for this in the system.

I did next Tuesday’s workout instead of a Ramp Test tonight. Afterwards I was told there were adaptations pending, and I thought I accepted them, but my calendar hasn’t changed. Can it take awhile to update? It’s been about 1.5 h. TIA

You ranked it a 3 and it downgraded? That doesn’t sound like intended behaviour; certainly not something I’ve experienced.

I’ve been ranking most of mine 3 (Hard), with the odd 2 (moderate) and 4 (very hard). I’ve not actually had that many adaptations, but the ones I have had seem in line with expectations.

General AT feedback from me - I’ve been doing ~3 TR workouts indoors per week (always done LV plans) and 3-4 outdoor rides per week since I got in mid-May. I guess this is fairly typical for many TR users this time of year. I try to do TR Tuesday and Thursday, club rides Wednesday and Saturday, then the 3rd TR ride Sunday although I have been skipping this if the weather’s good. After listening to the FastTalk on two-a-days I think I might try doing a 1hr version of the Sunday one in the morning then heading for an easy ride afterwards (the Sunday ride is often a cafe ride with my wife). I’ll normally then add in a TR TrainNow ride or an outdoor Z2 ride for 6 days a week riding, 10-12 hours a week on average for this year.

The only real issues I have had with AT so far are:

  • it’s obviously not directly accounting for all the outdoor riding in the PLs. I don’t really mind this. It does sort of indirectly account for them, since if you get fitter from the outdoor riding you’ll start rating the indoor workouts much easier
  • Outdoor workouts coming from Strava weren’t working even if they were done on Garmin - need to come from Garmin Connect. I’ve not actually done many outdoor TR workouts as I don’t have great roads for the intervals - I prefer to just stick to the turbo for the 2-3 “key” sessions per week and top up with outdoor riding (even if I do often have a goal in mind for the outdoor rides). I just accept this means my Endurance PL in TR looks low - it doesn’t really matter anyway since I only have endurance workouts in the recovery weeks and AT doesn’t seem to adjust the recovery weeks much anyway (I did a 10 hour ride on Saturday and a 4 hour ride Sunday, so you’d think my endurance was OK…)
  • Moving workouts around in the calendar broke the link to Plan Builder so if you moved next week’s Thursday workout to Friday, then completed a Stretch workout, it wouldn’t adjust the Friday workout up. Not totally clear if this is fixed yet. This is a bit of a pain for me as I like to move stuff around for work, social reasons etc.

I know my Sweetspot is pretty good, so initially I used Alternates to get a harder one as I could see the suggested ones were too easy, then it settled out at an appropriate level. I don’t really see this as a problem, but I can see how others might (based on this thread…) - presumably if it was way easy you’d rank it 1 or 2 and it would bump you up a lot anyway. But I am into Specialty now so there aren’t SS on the menu at the moment.

Yeah, it’s not the first time either. I had the same with a vo2max session yesterday (which is funny, because I thought I’d turned Adaptive Training off!).

That doesn’t sound like intended behaviour - I would raise it with support.

I did a Stretch VO2 workout yesterday, rated it as Hard, and nothing went down. I still have a Productive VO2 workout in the schedule tomorrow (which was rated Stretch before I completed the one yesterday).

Muck around with where your ant+ adapter is placed, makes a huge difference, I wrote an article here which I was personally amazed at the difference!

Thanks! That’s a really good article. Do you have any tips for Bluetooth dropouts on an iPad (newest generation iPad Air)? I run TR in my iPad often simultaneously with Zwift on. Mac or PC.

I don’t use Bluetooth much I’m afraid, I think it is more susceptible to interference than ant+ IMHO. Could it be that other devices are picking up/connecting over Bluetooth and hence the trainer is dropping one connection??

Thanks. I do not think my Rally XCs are paired to anything else via BLE. I do not think the Neo used to drop hs much but I have had BLE issues in the past with TR. Right now I think it’s the fact I’m in a hotel room with WiFi and devices everywhere and likely interference. I am still collecting files and overlaying them to see if I can narrow down the device. It seems like my Ant+ to my Garmin is good. Ant+ to my Mac is just as you described but tolerable. My Bluetooth to TrainerRoad has dropouts.

Quoting myself in another AT thread. For those seeing weird PL behavior:

From your Account, you can check your Adaptation History to make confirm, but the change in those workouts should be instantaneous on the web version of your calendar at the very least.


Are you referring to this in the ‘Known Issues’ section of the Adaptive Training thread?

That particular one has been resolved, so if you’re still experiencing it, I’d check in with to make sure something isn’t amiss.

This was on the team’s radar but not sure where we are currently. If there’s new information I’ll definitely provide an update!

EDIT: When you say completed a ‘Stretch’ workout, do you mean changed the workout assigned to a more or less difficult one? I may need you to get in touch with support for this so they can look into your calendar, what was assigned, completed, and how it effected the logic. Sorry for the trouble!

Thanks Ivy! I don’t have the same options you do. Other than the “Enable Adaptive Training” toggle, my page is blank. I did accept some adaptations last week, so i should have some history…
