Did TrainNow actually recommend that workout? That sort of jump in PL would be ranked as a Breakthrough workout. Pretty sure I’ve never been recommended a Breakthrough, though have manually picked them myself when I’ve been confident that I’ve done non-TR outdoor training which means my PLs aren’t a good reflection of my current capabilities.
Don’t know if this specific workout was recommended by TN but in general yes, this is how it supposed to work now, see:
Yes, I was cautious at first (thinking it was a bug) but was told this in another thread, went ahead and nailed the workout:
We updated TrainNow to use a machine-learning model to recommend workouts. Probably best to reference Nate’s post for details (linked above), but the TLDR is TrainNow is using a new machine-learning workout recommendation engine that the data shows will more accurately predict workouts that you’re capable of, regardless of your current PL.
TrainNow is recommending wildly different workout levels - #19 by nick
From where I’m sitting, this is as good as, if not better than the idea of WLV2 and unstructured rides contributing to the PL score. Presumably it is using unstructured rides in the determination but you have to verify the predicition to update the PL.
I love the idea of the updated TN and am hopeful that it’s a big improvement after Nate’s comments about it actually being better than AT! Can you explain the bit I’ve quoted above? I’m not following how you see these improvements to recommended workouts making up for not taking unstructured rides into account.
Indirectly: you do whatever work you do → your personal dataset is updated and taken into account by TN → you accept seemingly crazy TN recommended workout from official library → you’ll get your dearly desired PL update 
Doesn’t that mean that it IS using unstructured rides then?
I’ve been doing very very low volume sub-threshold work for four or five months and this week did a 3x10 to see where my FTP is. My V02, anaerobic and sprint PLs are 1.0 as a result.
Trainnow today recommends a level 10.0 (yes, ten) anaerobic workout, which would be +9. You think that’s a bug or maybe I might be able to do it?
Don’t really know but if unstructured rides are taken into account for AI FTP, only conclusion can be that TN has to take it into account as well (probably with some delay, not immediately after completing ride or even next day).
They are.
Only after 10 indoor tr rides though right?
Correct
Why ? They are two completely separate systems that do different things, I’m not sure why it can be “the only conclusion”
True, that’s why also used words like “indirectly” and “probably with some delay”
you didn’t use the word indirectly
and the probably is about a time delay … not that the are probably (not) using outside workouts in TN
Excuse my word salad.
To clarify, I’m not fussed that unstructured don’t make the visible score go up. I’m happier that the ML does consider them and that once I’ve completed a TrainNow ride and verified that I could complete what was set out, then the score goes up.
Discussion started bunch of posts before that actually, with little bit more context.
Anyway, there is no point arguing one way or another. This is just us, ordinary forum users, trying to interpret what CEO or members of TR has posted in various topics.
Gotcha! So, if you go do an outdoor ride with some long SweetSpot intervals (for example), then TrainNow will take that outdoor ride into account, and feed you an appropriate SS workout based on those efforts. Assuming you then nail that workout, your SS PL goes up. Did I get that right? Pretty cool.
Exactly, that is my hot take without knowing what’s in the secret sauce.
I’ll continue to check TrainNow after rested days, try and see if I can complete other PL zones with big jumps and see if this theory holds up.
Thanks! Just had a look and now seeing similar recommendations - my VO2 and Anaerobic PLs are currently 1.0 as haven’t done any TR workouts in those zones for quite a while though have been sprinkling in some efforts on my long outdoor rides. Trainnow recommending today that I do a level 8.7 Anaerobic workout which is a huge jump but not all that different to what I’ve done manually in previous years (at any given FTP I always seem to find it much easier to get towards the top of the PLs in VO2 and Anaerobic than I do in Sweetspot/Threshold, so starting at 1 and doing Productive or Stretch workouts takes a month or more before any of them feel challenging).
Would say there are still some bugs to iron out though. As in the other workout zones it was also recommending a Threshold 9.9 workout. I’m currently down at PL1.3 on Threshold which is probably a bit lower than I’m capable of (Sweetspot is on PL6) but I also know from experience that trying to jump up the Threshold levels the same way I can jump up the VO2 levels will end in bitter failure quite quickly! Hit Refresh and it changed to a Threshold 5.0 workout. Which is maybe manageable but a completely different proposition to a 9.9. Doesn’t seem like it should be recommending such a huge range of workouts just by hitting Refresh.
