AI FTP Detection Is Now Available for Everyone! 🎉🎉🎉🎉🎉


Ok I’ll ask the obvious question:

What about overestimate vs ramp test? Any data vs 8-min test?



I’ve found it so simple to use I forgot it was in beta! I saw this post and thought duh. Then I realised it’s now officially released lolz.
Great idea, easy to use and so glad I don’t do ramp tests anymore.


Congrats to the TR team on getting this out.

I’ve a question on L:R power balance and how this impacts the AI FTP.

I use a Neo turbo indoors and during the drier months, I use Assiomas outdoors. I don’t really want to keep replacing Assioma bearings throughout the British winter and want to use a simple left-hand crank meter, probably 4iiii. However, my Assiomas indicate a 44:56 power balance.

If I swap around power measurement devices I’m guessing with my power imbalance that this may impact the usefulness of the AI FTP?

I know I can use scaling on the left-hand crank, but what should I set this to? I don’t know whether the balance is closer to 50:50 at higher interval wattages vs lower power outdoor cruising around rides.

There has been plenty of discussion about TR not visualising L:R balance or even allowing it to pass through to other ride sync sources. I think the rationale is how does it make the rider faster to have this data. Could there now be a case for recording L:R balance and even for the AI FTP data to prescribe the scaling factor when using different power measurement devices to assist AI FTP usefulness?

Cheers Scott

Well done TR. So glad FTP AI is now automatic.
20 mins Ramp tests are a crazy VO2 test in my opinion. Highest score I ever got was 242. Though I have managed 290 NP for 2 hours on Barren. Therefore, I have managed my FTP manually. But today TR AI has given me a 300 FTP !!! Happy days. 5 above my manual prediction


I’d forgotten this was in Beta to be honest, great news.

I’m a little confused as the FAQ article indicates:

  • Indoor workouts with power
  • Indoor workouts with only an HR monitor
  • Outdoor workouts with power
  • Outdoor workouts with only an HR monitor

But the above abridged version suggests only power is used.

Can someone confirm which is correct?


Nice :+1: now for the next step, are there any plans to recommend certain types of workouts and schedule to an athlete which would maximise their FTP growth (instead of the fixed training blocks)?


AIFTP is the best thing since sliced bread (or actually “alternates” in the TR-world :grinning: ) I’ve always struggled with the Ramp Test, especially at the beginning of the plan when switch to indoor training. Workouts have always felt too easy. E.g. I never understood the fuzz about O/Us being so hard. This season AIFTP has given me an ATH FTP for season start. Ego feels good, but the legs hurt :crazy_face: And now I finally DO understand the fuzz about O/Us…

My only concern is similar to what was posted above, namely multiple power sources. I use a Kickr Core inside, and have a dual sided 4iiii on my road bike. They work pretty well together. But I am reluctant to drop any money on a power meter for my mtb. Different bike, different meter, different type of riding. So at least for me I’ll be riding the mtb by RPE. Saves me some $$$, but I do miss some structure and numbers…

I made the move from Zwift training to TR in June and it has to be said TR is working really well for me. The AIFTP and AT pairing seems to work just perfectly for me. I’ve managed to go from 226w to 263w according to AIFTP.

The thing is I don’t know if those numbers are ‘correct’ but what I can tell you I do feel over 15% stronger and I do think that the training is aimed correctly at me… all workouts seem to ‘do the job’

Keep up the good work guys.


Huge congrats to the TR team! I sincerely think this will be a massive game changer, not just within TR, but for power based training across all systems.

Now that it’s live, how can we remove all the ramp tests from our training plan, and have them replaced with the optimal workouts to compliment the rest of the plan and continue progression most effectively? Seems quite a heavy restructure & reshuffle of the entire TSS build within the Ramp Test weeks would be called for, possibly switching the other workouts and focuses in those weeks entirely.

It seems at first thought that a lot more progress per month could now be made both within those weeks, and in your plan overall, now that these “completely fry yourself” efforts every 4 - 6 weeks have been removed. I’m guessing fully capitalizing on that will need pretty deep plan restructuring, at least within those weeks, not just manually swapping the Ramp Test for a randomly chosen workout.

Particularly for riders partway through a 6 - 12 mo plan, ‘Delete and build a new plan.’ may not be a great option.

Apologies if I missed an already existing answer and/or How To, but had a real search both on site and forums, and couldn’t find it!

Thank you for an AMAZING quantum leap forward. Can’t wait to see where it takes people!

  • I don’t think they have a setup that just swaps them all out in one step.

  • Per the defined process, you run the AIFTPD tool by clicking the button located next to your Ramp Test on the calendar (as applied via plan addition or manually adding a RT). You run that detection, accept the result and will be offered a replacement workout if you choose.

  • Essentially, you just do that detection & swap as you get to that point in your calendar, not ahead of time.

This is a tricky one. You’re basically saying that one of your power meters doesn’t measure power the same way as your other power meter.

There’s a sideway into this. WLV2 takes into account indoor and outdoor power and might do an offset depending on your historical trends. So if you’re always lower/higher on one, then it should take that into account…if it’s consistent.

The team has an issue to do not just splitting indoor/outdoor but do it per power meter. But that’s a little lower on the priority list since not many people ride consistently with three power sources.


Rides with just HR are considered, but it’s always better to have power on all of your rides. It’s easier for the ML to figure out your FTP if you have power on all of your rides.


We’re always working on optimizing training. In our next release, we’re going to take people to different progression levels depending on your plan.

The current plan is, if you’re in specialty, we’ll let you train up to level 9-10 in your primary zones. Then if you hit that, we’re just going to bump you up 2% so that you don’t get a drastic FTP increase and start lowering your TIZ or how many repeats you’re doing.

IE if you’re in week of 6 of 40k TT you don’t want to keep practicing your sustained power at really long durations rather than building up from a new FTP.


Yes, we have two phases for this:

Current release: If you have a ramp test within 28 days of your last AI FTP Detection it will be replaced with a workout.

Future release: AI FTP Detection goes full auto, and you’ll have the choice not to have tests on your plan. After 28 days, we’ll automatically run AI FTP Detection after every workout and let you know when it increases in a meaningful manner.


@Nate_Pearson Aaaaamazing!! You guys ROCK my CASBAH!!!


Had originally posted this in the other AI FTP thread and the thread got locked like an hour later :confused:

"Looking to add some extra ‘volume’ to my low volume traditional base plan I am doing over the winter (in week 2 of Trad Base I currently) and would like to choose the option that will have the most impact on my AI FTP. Which of the following options would help boost my AI FTP calculation?

A) choosing a higher PL workout as an alternate once or twice per week (Klammspitze instead of Fletcher, 20 more TSS, extra 30 mins, 0.1 lower IF, 0.4 higher PL)

B) adding an extra lower level endurance workout once per week (For example Carter, 3.3 endurance, 34 TSS, 45mins)

C) adding an extra lower level threshold workout once per week (For example Sanford -1, 1.5 threshold, 50 TSS, 45 mins)

Is the answer based on boosting your TSS the most or your PL? I can only do so much but with the extra work I put in whether it is the same amount of workouts but harder or an extra workout, I want it to have the most impact on my FTP.

I expect both are factors but at the start of this plan AI FTP suggested a drop (I rejected it) put in a ticket and they couldn’t tell me why a drop was suggested but have continued on and haven’t had an issue.

If someone like Ivy looks into things related to that, I also had an issue last week where I did my Sunday workout (Gibraltar -3) on Saturday and it disappeared from Sunday on the App but stayed on the Sunday on the web calendar."


Sounds like you’re saying I’d be wasting my money buying the left only 4iiii. Just going HR only seems a shame after all your teams hard work. I’ll have a think about what the best vfm, wet weather total power meter might be. It could be use the Assiomas and accept the bearings might need a couple of replacements over the wet months.

I would use a left-sided only PM over a HR monitor, even if your situation.

If your offset is consistent, then you could use the offset feature in 4iiii software


Congrats to Nate and the TR team! You all should be very proud of your hard work. This ecosystem of AI FTP detection, Progression Levels, Adaptive Training, TrainNow, and the podcasts makes TrainerRoad such an amazing training platform. I love it. Especially TrainNow which has become my main way to train.

I was in the beta and can say that AI FTP detection was accurate for me whether going upwards or downwards, the subsequently prescribed workouts at the new ftp just felt right and productive.

Thank you!


Last season ended with the typical tapering week, followed by my A event and 7 days completely off the bike.

Then, AI FTP suggested a ~5% decrease, which I obviously rejected :stuck_out_tongue_winking_eye:

I worked so hard to get to 4+ Watts/Kg, I didn’t want to lose those last 25 watts for the upcoming season. :smirk:

Fast forward three months and the entire subsequent SS HV block felt hard. Literally, I rated all SS workouts as hard, except for one moderate, two very hard, and one all-out. :unamused:

Now I’m ending my recovery week, heading to “Build” and I’m wondering what AI will think about those “hard” answers I gave on the surveys. :woozy_face:

Furthermore, I’m still unsure why AI FTP detected I should decrease those 25w. Was it because of the tapering, the seven days on the couch, or something else? :man_shrugging:

And, I’m also wondering whether I made the right call to reject that 25w decrease, or not. :thinking:

What do you guys think?
