Hard days: Stick to prescribed power or go harder if possible?

Hej,

I got another question regarding a different aspect of training:

Almost all “hard days” I overshoot power in intervals and recovery. What’s labeled as a 3diamond workout before gets always flagged as 4dia afterwards. But that does neither mean I cannot finish the workout, nor do I get breakthroughs there - since my goal was to do intervals, not get BT :smiley: But since it’s not altering my Fitness Signature, that again means the next workout will likely be too easy again…

So: Should I stick to the power on my headunit or should I go by feeling?

Part of the question stems from an imperfect understanding on how the intervals are prescribed - I hardly get intervals above 3minutes, so I figure that also means going harder rather than easier. In classical FTP models power always way above threshold, more like VO2-zone, although not long enough to get HR that high… Also with the MPA chart being orange/red in the intervals it signals me to “go hard”, too.

So that confuses me a bit and I dont know if “easier” intervals is a deliberate thing or an error in my understanding/execution of training :innocent:

EDIT: I sure would be able to switch workouts manually every time, but quite frankly: one part of why I pay for is the convenience to not have to do that.

Thanks and cheers from germany

As an example:

Born to greatness
should be: 3dia, XSS Breakdown 87 ( 72 | 12.0 | 2.7 )
did it as: 4dia, XSS: 128 ( 99 | 22.3 | 6.6 )

When was your last breakthrough? Could be an underestimated signaturen.

Oh, I just noticed I didnt send the answer I typed yesterday… well, there’s (confusing) updates anyway :smiley:

My last BT was roughly 4 weeks ago, it was a gold one and I think it was pretty spot on with what I felt is my TP.

Today I had a hard day with “One Step Closer”. I didnt feel strong this morning, because I slept in and was on the bike within 30min without properly hydrating or eating. Also I had to stop the workout 15min early, too, because I had to get ready for work (sleeping in-tax :sweat_smile:).

So I skipped 4 intervals, but I’m not sure if I even wouldve been able to finish them anyway. Or I would at least have had to straight out puke afterwards). Nevertheless out of guilt I decided to still “reset” at least my decayed PeakPower and did just smash it in the last interval just as high as I could go:

Well … I didnt even go as hard as I usually go, but wouldnt have been able anyway. Secondly I only tried to reach PP and I felt like shit and still XERT thinks my TP jumped by 50W? Thirdly I’m fairly certain I could not hold 260W for 40-70min let alone 30. Maybe 20min TT(complete)E, but even that I dont feel confident in. RPE and watts today seemed reasonable, so I do not think it’s a technical (=calibration) issue, either.

Further: 14d ago I did One Step Closer, too. Not only did I complete it, I was pushing slightly higher watts throughout and got more TSS for the same part of the workout - but got no kind of BT though :smiley:

2weeks ago (I even added 5min slightly above TP at the end):

today (adjusted to TP/HIE/PP of before):

I’m so confused right now :face_with_spiral_eyes: :sweat_smile: :zany_face:

Peak power efforts with an abrupt stop is known to overestimate TP. If you know the new TP value is out of reach I would flag the activity and then manually adjust the PP if thats a true value. Click on Extract and Save if the new signature seems reasonable.
