Just wondering if people have field tested their AI FTP numbers? Post below if so, I don’t think mine is anywhere close to what I could do, and planning to test soon so that I have a pacing number for race season.

I say test it. More data points are good to have. It will be interesting if whatever test you do produces a different number, and then if ai ftp changes because of your effort. Cause it it does adjust, then id say theres a problem with the ai. Let us know how it goes

Measuring FTP is an estimate of an individuals lactate threshold/MLSS. I hope that’s not a controversial take. I also consider TRs AIFTP detection is an estimate of the same. It doesn’t make sense to me to compare an estimate to another single estimate. If validating AIFTP estimation, at best, yo…

[image] OreoCookie: To me every non-endurance workout is a test of my abilities and yields a data point. I don’t need an FTP test of any stripe, e. g. a threshold workout will give me a good indication of my abilities. I agree. I’ve trained and ridden long enough that I have a really good se…

[image] timon: but it is simply not FTP by either the original definition by coggan, or any widely adapted iteration that’s come and gone in the past 20 years…. Just to add to that: Coggan alone has changed his mind on “the” definition of FTP over the years. Machine Learning (the way it is us…

[image] OreoCookie: Even within the “accepted definitions” — or rather, most commonly used FTP test protocols, there is a lot of variability. Yes but does anyone up to this point (including all of Coggans changing views) have a definition of FTP that says you can’t do 4X12 with 6mins recovery…

[image] Saddlesaur: From what I think I understand from other recent threads, the new AI would not utilize or be affected by the FTP test result. I thought that it would only be seen as a workout, but Eddie corrected me here [image] Manual FTP throwing off prediction T…

[image] timon: It’d probably be a 50% failure rate without that drop. A 50/50 shot at making it an hour sounds like a pretty traditional definition of FTP to me.

[image] timon: Yes but does anyone up to this point (including all of Coggans changing views) have a definition of FTP that says you can’t do 4X12 with 6mins recovery on a normal intense training day at less than your FTP, but that’s your FTP? That’s fundamentally what this new TR AI model is se…

[image] OreoCookie: Just to add to that: Coggan alone has changed his mind on “the” definition of FTP over the years. Machine Learning (the way it is used now) wasn’t a thing nor was there a corpus of data comparable to what TR has, and a “definition” via ML algorithms wasn’t on anyone’s radar, …

[image] BenB: Did you mistype something here? Generally the easiest workouts you get after an FTP update are over unders for a couple sets of ~10mins, and they are expected to be rated hard mostly, not all out. No? If you’re calling a number your FTP, I’m of the strong opinion you shouldn’t …

Anyone field testing the AI FTP number?
