Hi everyone, I have become a little obsessed with the ftp estimator. I have used it twice in the last four weeks (can only be used every 14 days) and went up 11 watts each time. I accepted it both times and while my first few workouts, especially threshold, were some of the toughest I’ve ever don…

I’m suprised noboby else mentioned this. I will only change my FTP according to the plan (in fact I’ll actually do a ramp test), but a few times a week I take a peek to see what my FTP “could” be. I manually add an FTP test for the day, get it to calculate my FTP, reject the answer and delete the s…

I did that too, for science but even completing stretch VO2max, threshold or sweet spot workouts didn’t alter the estimate in fact sometimes it was lower after a hard workout

Interesting, I hadn’t considered that complexity. I’d always assumed that lower PL on a higher FTP would equate to the same outcome. Would be good to see if there was some data backed verification of your 5% rule of thumb.

Well, I am not claiming any hard data background with the 5% value. It is a concept, that if there is a notable change in FTP, you are likely better to accept it. Specifically, consider the simple case of training at Threshold of 100% FTP. If your FTP value is off by 5% or more, you are very pos…

This is how my obsession with the feature began. Two weeks into SSB 2 I was curious to see if I increased since I manually tested at the start of the training block and when I saw I had gone up 11pts, I decided to accept it since it seemed like a significant increase to me. Then two weeks later, I…

I wouldn’t do it more often than is scheduled in the plan. The exception being if you are completely new and improving on a week to week basis or coming off a long lay off, sickness, injury, etc. As has been pointed out, if you are constantly upping your FTP you’ll never get to those ‘harder’ work…

I’m keeping my ftp where it’s at til my threshold level gets to at least 5*. This way I get those longer intervals in the “ zone”. Also after a season of short power build my muscular endurance is now my weakness .

Good thread, I learnt from this one. Thanks all

Me constantly asking AT if my FTP changed: [Crunch the Numbers]

Can’t you use the estimator every day if you want? Or did they change that? I check it when I’m curious, but accepting it is another matter. I only plan to accept any change when the new FTP changes quite a bit and my PLs are out of wack.

To illustratrate your point, today I accepted a change from 246->254W 2 weeks after and this is what happened (tldr my planned threshold workout changed from 3x15 min @246W 75 mins to 3x12 @ 241W for 60 min with my new FTP) , so increasing my FTP by 3.3% actually made my threshold workout easier:
