Bike HIIT targets seem high

Hi folks,

Couple of queries at the moments. I would guess by feel my ftp is 240w to 250w (garmin says 241) the profile has my cp at 204 which seems low?

The profile has my map at 275 which also seems a bit low. However the HIIT intervals seem to be high 30/30 is at 371w and 20/40 is 721w ?

This evenings short run came over with out any data a bit like the issue last week?

Thanks

Having the same issue with completed sessions not uploading to Athletica today (11/7/2024).

I was also drafting a similar question from yesterdays VO2 20/40 intervals. Session was uploaded to my Garmin head unit and using a smart trainer in ERG mode. I’m in the big chain ring for the front, and the middle for the rear gearing (17). Warming up well, RPMs in the 85-90 range, matching my target power is 133w. When the 20" intervals came about, the trainer increased the resistance. The target power is now 611w (Range of 327-938w). My cadence dropped to the 40’s and I am standing on the pedals doing my best to churn this out. Is this what I should expect? Should I be changing gears?

Thanks,
-Joe

Nope at the cadence it’s a power workout. For HIIT i’d expect to be 90 to 110 rpm.

Pablo_ie thank you for replying back. So for this Short HIIT 20"/40" interval ride. The significantly increased resistance with low cadence is the intent of the session?

I ask because I have done Strength Endurance sessions were the intervals are specificaly prescribed as Low Cadence (40-60). The power range for these was between 175-218w.

The two, to me, appear to have two different cycling specific goals. Thoughts…suggestions…

Sorry for the confusion, i mean the opposite in a hiit session I would expect the cadence to be high.

Hi Folks any thoughts on the high hiit targets?

Hey @Pablo_ie

I will flag @Andrea here - he is your man to answer your questions about the target power HIIT sessions.

Thank you so much @Pablo_ie and @KinesioMS for these messages.

What you are highlighting is that the 20":40" sessions are prescribed at Z7 intensity, which is wrong. I’m so sorry for this, but somewhat the wrong zone entered the template session. We know that those intervals must be done in Z6, which is why, most likely, you did not find them to be effective, or pleasant.

I’m so sorry you had to exert yourselves during these sessions. I will address ASAP, most likely during the WE.

As correctly @Pablo_ie points out, a HIIT VO2 session should be carried out at a relatively high frequency/cadence, i.e. 90-110. Those low cadence sessions have a different physio target in mind (much higher neuromuscular component because of the high torques).

PS, @Pablo_ie , I had a look at the data, and to me there is no evidence to suggest that FTP or CP are wrong. I do not know enough about Garmin to be more specific on the reasons behind these discrepancies. Please be aware that we keep your maximum efforts into account for the calculation of your profile for a maximum of 6 months (which is already pretty long). I do not know what Garmin is doing but perhaps they keep your historical data for longer. As you can tell from your profile (which is quite nice) the critical power nicely lies on your max efforts, settling down at 204 ish. Even If I take the 95% of the max 20’ effort of the last 3 months (FTP estimation), I get 220*0.95=209 W.

Hey @Andrea

Thanks for checking the CP. Are the hiit intervel targets of 371 correct. Previously they would be 286ish.
Thanks

seriously: it’s all wrong with training targets. I just turn to RPE all my workout on athletica.ai. Otherwise, it’s no sense and unreachable Watts most of the times.

Hasn’t been a problem before, I trust the process this just seems off.

@Pablo_ie for the 30":30" intervals your targets are fine and in Z6 as they should be. Somewhat we had the 20":40" seconds intervals (those pulled with the WW) in Z7, which will provide as wrong target. So, it should all be fine for your next 30:30 on Thursday.

@Joe can you please be more specific on what is “all wrong” with the training targets? What modality you are referring to? What metric is off? Bike/run/swim/row and HR/power/speed? Please DM me if you’d like me to have a look at your profile, I might need your use name.

Andrea, Thank you very much for the follow-up. I will be looking forward to the next session on bike. All the best.

@Andrea, my cycling power profile says 275w, which is in line with the 30:30 intervals targets were when I was training a lot more. A target of 371 is close to my AC profile of 432 from a 4dp test. Something ain’t adding up for me !!!
