AI FTP prediction depreciates

I was getting demotivated because my predicted figure dropped from 258w to 252w even though i was sticking very closely to the plan. I’m sure there was logic to it, but it gave the impression of being illogical. E.g. “it dropped because you’re in a recovery week” - it knew i would be in a recovery week when it gave the 258w figure, because the plan told me to do a recovery week! Every day I stuck to the plan the prediction changed!

I fully understand what you are explaining and I can agree with you for some degree. There is only the question (my question) how is it possible that AI is suggesting a workout and suggests a workout feeling e.g. “easy” I follow the workout, the garmin also says “completed 90%” so that’s a good followed workout (when saying it myself). But why sometimes the ftp prediction sets my future predicted a couple of watts lower instead of higher of equal after this workout?

I’v also do a HR check if this happens to see if the hr is higher, and it is not, EF, IF, pwr/hr are the same as other simular workouts. So for me, the AI is calculating something wrong.

Know, I’m not the only one seeing this happen…. But as said in my post, I’m done with it. Will come back when the AI model has been tweaked for getting better instead of worse :laughing:….

That would depend on the workout that was missed, and the expected impact of that workout. If you missed a 30 minute endurance ride, maybe not. If you missed a 2 hour interval ride, it might.

This is where my mind is going as well. The new AI doesn’t seem to be working all that well.

As always, nothing anyone can say about your situation without your calendar. But I’m not saying that would help either. Taking everything you have said at absolute face value I’m not going to claim to understand the causes behind edge cases like yours. For the vast number of riders the system is working very well.

Have you opened a support ticket with TR? Might be worth doing.

@jbakkane @duursportersweb I’d be happy to look into your cases. Can I share what I find in this thread?

Yes absolutely, I probably need a good roast :face_savoring_food: :sweat_smile::laughing:

I have no intention to roast you! I haven’t even looked at your training yet – I just wanted to make sure this is the place to discuss before I do.

I’ll let you know what I find..

It looks like you’ve struggled with your last four threshold workouts.

You marked last week as “hard,” which seems off if you had to backpedal (that’s been discussed already). The week before was “very hard,” which is a better response, but it looks like you actually struggled more during that workout, so I still think that might qualify as a “max effort” workout.

Two weeks before that one (there was a rest week between), you said that stress/motivation was the issue, and the week before that one, you made it through one of the overs and then rated the workout as “easy.” :thinking:

That leaves February 26th as the last threshold workout that you completed and had a seemingly appropriate RPE response. This makes it hard for us to know where your fitness is actually at. Because of that, your FTP prediction will change somewhat regularly…


If any of those survey responses aren’t appropriate based on our guidelines in this Help Center article, I’d edit them to help us better understand where things are at with your current fitness.

Otherwise, do your best to get through your upcoming workouts as best as you can and answer your surveys honestly with our guidelines in mind. :+1:

Let me know if that helps!

Well 95% of 255 is 242… so you are saying your predicted AiFTP is too high? :wink:

Thanks for the input Eddie. I’ve been struggling to fit the threshold workouts on a good day. I’m more of a VO2, Anaerobic guy, so these are hard for me. The failed ones on Base 2 Week 2 and 3 were both because I raced Zwift on Tuesday. So hard workout Monday, race Tuesday, after a big Saturday ride, my legs were cooked, so I just bailed. But yea, I’ll go back and updated responses and be a little more critical.
I also, think I need to move the threshold workouts to Friday, so I get another day to recover before them. I do feel like it’s a focus thing as well. Some teammates recommended doing threshold workouts on Zwift, so you can have targets. Like in a climbing route. It’s like that mental thing about going hard on the downhill.
In general it’s hard to see a FTP decrease after all the hard work I’m putting in. I’m very limited on time, so all my workouts are hard.

Thank you for putting in the time though. I’ll look it over again.

No worries! I’m always happy to help however I can!

I think moving those threshold workouts could help out a lot. :+1:

If, at any point, you find that you simply don’t have the energy for them in your week, you’ll have to replace one of your hard days with rest or easy riding. More isn’t always better, and if you prioritize those Zwift races, then it’s okay to pull one of your hard workouts so that you can be rested and perform well for both of them.

In terms of training motivation, doing the workouts in Zwift is definitely an option, but just make sure you’re sticking to the structure of the workout. If you’re breaking away from the power targets, you’re not getting the intended training stimulus, and it’s hard to compare that type of effort to the workout we prescribed.

Doing the work in TR works just as well in terms of training stimulus, and some may have better results without the distractions of climbs, sprints, and other riders. That’s totally up to you, though!

If it was that easy I would probably train 110% of what TR sugests :laughing:

Yes did a couple of times and the support is GREAT!!…. No complains and as said before, I have no complains what so ever, the only thing is that Im not struggling with the proposed workouts, most of them get the RPE as thought by the system. And that Im not getting better… Att you see my ftp history from 2023 on and no progression. But hé, I believe that some are getting better, but not me. I also know, ftp is not the only metric for progression, but it is a metric that shows your current level. Still competing the athletes as I started before with TR.

Hi Eddy, sure, share what you see, but bear in mind that I already gave up and started doing my own thing…

You were very helpfull in the past, the plan I followed (ftp plan), you put in my calendar after your last help with my same issue (not getting better)..

So share what you see….

For your information, when I hear friends, who are on another training platform, when doing an Vo2 or higher training they are gasping for air, I never have that…surprise me, maybe you can show me the holy grail as my major A race is around the corner (Traka in Girona)..

If I do the workouts in Zwift, it’s linked to my TR account so it would be the one prescribed. I would do it in ERG to make sure to hit the numbers.
I’ve decided to accept the -1w FTP. It’s just a training number anyway that AI is guessing on. So I’ll focus on hitting my workouts and it is what it is. I’m pretty happy with where I’m at right now, and all my friends are all amazed at where I’m at with the little I do. But like you guys preach and from what I’ve experienced, I keep riding TR all year, twice a week hard intervals and a ride or two outside and it ads up. I almost never miss my two TR rides.
With this FTP and with finetuning my upper end for the next month, I should be pretty well set for my main event.
Thanks again!

Haven’t had this happen to me yet but I’m only a couple weeks in. I have been peeking the workouts beforehand and they show an “AI Predicted Difficulty” and it’s been pretty accurate to date. My theory is if our difficulty ratings match the average AI Predicted Difficulty, then the predicted FTP should stay on target. Likewise I’m curious if rating workouts easier/harder than the AI Predicted Difficulty changes the predicted FTP, but better to give a truthful response than trying to game it and failing future workouts. The scale I’ve been using for rating is something like:

Easy - Could easily repeat workout
Moderate - Could do another set of intervals
Hard - Difficult, but could do one more interval
Very Hard - Struggled to finish, could not do another interval
Max Effort - Had to turn down difficulty

This may come across as rude, but maybe you’re at an age where FTP gains aren’t fast, or maybe even possible. In one of your comments, you mentioned being a pro-triathalon athlete in the 80s and 90s. I’ll assume you were 20 in 1990, which would mean you’re at least 56 years old.

You might already be close to your physical peak. And even though your FTP might be stagnant or going down slightly, your fitness level compare to your peers might be increasing, just because you aren’t dropping as fast.

Your not rude at all… Im from the Netherlands and you can say all as we believe it is all for the best also in this case​:winking_face_with_tongue:. Regarding your comment, I’m 61 years old and know that my ftp increase will not be the same as when in my 20’s. i also know that training not works as put a workout in and instant you get xx watt. My point is that besid I’m not getting better (not even 1 watt) but getting worse is strange with an ftp plan. When starting a new period. Startpoint was 255, first future prediction was 269 (or so) followed the plan and ended @ 253, later 250. I accepted the lower ftp to not disturb the plan. As I gave up, I did my own free ride yesterday (5h+ 309 tss) mountianbike single tracks only ride. TR planned that day to give me 253 ftp, but I did not do the TR workout, i did this ride and ended op with 244 ftp.

So if on one hand a good workout will not give you instant ftp, a bad workout will lower it instant (in my case with 6w. The new ftp prediction in about 4 weeks is 259 on May 3rd wich is my A race of the year,the Traka Girona.

Let me again say, nothing bad about TR, helpdesk, etc.. but think the AI needs approvement. Maybe the “magic saus” that Jonathan mentioned in the podcast :blush:..

Thanks for all the input….

I think TR is designed that when following the plan, rate as the prediction suggest, you should gain the watts ftp been calculating the calender 4 weeks ahead.
