What’s happened here then?

[dsirrom]

So due to a knee injury I’ve only been doing infrequent Z1 / Z2 indoor rides for a few months.

as expected, my AI FTP has dropped from north of 300 down to 258.

All my PLs are back down to 1.0 apart from endurance which is at 2.4 because of a 2 hour spin I did at the weekend.

I completed a straightforward Z2 75 minute TR workout last night (PL 1.5) and rated it as easy.

the AI did its thing and spat out the adaptations to PLs below

Seems I’m now superman!

Anyone have any idea what I did wrong to trigger this weird change? My power meter was fine and so was my HRM. No spikes in power during the workout.

More importantly how do I reverse out the wacky increases so everything goes back to what it was before?

Welcome to the new TrainerRoad Ai.

Did you not get the pop-up when logging in today telling you that the new Ai was beeing used with some slides showing whats new? In either case with the new approach your levels are set at a starting point based on what the Ai thinks you can do. If you hover over the different levels, does it not say Initial Level?

Edit: And no, you can’t go back. This is the future.

This is (probably) what the system thinks you can do, it isn’t strictly wacky, when the knee is better, load up a workout and see if it is right.

It could always be a bug too

I see this as a recognition that the previous approach of having your PLs decay all the way to 1.0 wasn’t great. Injury aside, you probably could do a 4.0 level VO2 workout

Did the drop to 258 happen AFTER the PL2.4 or PL1.5 ride was completed? If so, and this is a guess, is the 1.5 or 2.4 at 300+ the equivalent watts of a 6.5 at 258? Look at the watts of both workouts, not the PL.

Metrics on new AI FTP Detection + TrainerRoad AI

Hey ya’ll! We’re slowly rolling out TrainerRoad AI to people today. There’s been some confusion and misinformation going around, so I wanted to start a new thread to try to clear some of that up. What is the new AI FTP Detection? The updated AI FTP Detection you’re getting puts you around a level 3 threshold level. This will be consistent between detections, and we think this is a good insert point into your overall zone progressions to get faster. The old AI FTP Detection was predicting …

TrainerRoad AI FTP Prediction FAQs

We’re slowly rolling out the new TrainerRoad AI today, and I want to answer some FAQs. What is AI FTP Prediction? AI FTP Prediction simulates your planned workouts in your calendar and predicts your FTP on the prediction date. Your date is initially 4 weeks out; it will get closer as you approach it. You can change your planned training and see how it impacts your FTP; it’s super cool and my favorite feature. The simulation uses our predicted difficulty and predicts the most likely FTP you’…

No - my FTP initially dropped to circa 270 ish after I’d done very little riding between end of September and sole time around end of October (I may be off by a week or so). Then - although I then started to do a tiny bit more riding, it was at z1 and Z2 and really very little compared to before the injury.

AI FTP dropped again to 258 a couple of weeks ago. I’d been pootling along after that doing more z1 z2 stuff infrequently and then did the 2.4 PL

I confess I’ve not been checking back in this forum for a while now so missed the whole AI upgrade announcement thing. I also didn’t see anything pop up on my iPad last time I rode?

I’ve now checked out the FAQ thread on the AI.

I’ll just keep plodding along with low level z1 z2 rises and then let the new PL levels drop down again. Prognosis for my knee is months rather than weeks to be better, so I have time to just keep maintaining easy base miles and hopefully the AI will get itself back to reality.

I know myself and there is simply no way I have the current fitness (regardless of my knee injury) to complete a workout at some of those PL levels at some of those intensities!

Will be interesting to see what happens after your ride on Saturday. Heal up!!
