I’m doing ,80 IF rides on Saturday and my Sunday rides get reduced from 1:30 to 0:30. I’ve been rating the Saturday .80 IF rides at 6 or 7 out of 10. I don’t feel like they are extremely hard. What factors are causing this? Help me understand….
So you’re the bug that is slowing the upcoming release

Without having more information about your overall training plan, and how you’re rating other workouts, it’s very hard to say. I would guess, though, that the AI logic thinks you’re pushing things too hard and need a bit more rest. The latest podcast (with Hannah Otto) might be of interest to you.

I’m only in week two, so I’m assuming AI is figuring things out still….?
Probably that.

If you are rating them 6 or 7, I take it you are rating them in Zwift? You might want to ignore the Zwift rating and use the TR rating instead, no idea why they went with two different rating schemes, but they don’t always line up perfectly. Also, although you are being recommended 30minute workouts, you can ride for longer if you feel okay, as you say, if you’re only two weeks in the system is probably learning about you, it’s probably okay to give it a bit of a nudge, I really don’t see much point to a 30 minute ‘endurance’ workout.
Do you get an RPE scale from 1 to 10?!?! Mine is only 1 to 5 which I find super annoying especially since you have to deep dive to figure out what that scale means.
The 1 to 10 rating is what you get if you push your workouts to Zwift, it pops up at the end of the workout. If you do the workouts in the TR app you get a 1 to 5 rating choice. Why there’s a difference I’m not sure and I’ve never seen an explanation for it. It is a bit strange having two different rating systems for the same workouts, but there you go. Every other site app that I’ve used from Garmin, Intervals to Training Peaks use 1 to 10, and it’s also the scale my physio uses for pain! No idea why TR is one to five.
Try increasing the AT slider a notch.

The scale I referred to is on Zwift, not the TR scale.
Hey @pgrayam 
What you are experiencing is our Fatigue Detection at work! It looks like you just started training after a few months off the bike, so the system is likely ramping you up slowly so you don’t overdo it.
The aim of our fatigue management is to prevent long-term fatigue so you can keep your training productive. As you give the system more training data, you’ll see the Yellow/Red Days naturally change.
Thank you for the response!
I was off the bike for a week or so before starting TR, not sure why it appears I was off for months?
I’ll trust the system, but just feel like I’m not getting much riding in compared to what I was accustomed to this year and actually feel as if I’m losing fitness since I’ve started.
Out of curiosity, how is the fatigue measured? I’m completing the workouts and at the watts prescribed? I’m assuming my heart rate?
Historically, I’m a “grind it out” style rider at lower cadences (70-80). The higher cadence (85-95) of my workouts tends to make my heart race a bit higher than usual, which I suspect is causing the fatigue detection? I feel good after the rides…
I’m not quiting by any means, just trying to understand things better so it doesn’t impact my enthusiasm….
