What's the running equivalent of Tadej Pogacar riding ~7 W/kg for 40 min?

For any cycling uphill power calculation, the weight has by far the highest influence. The mass (its more correct as weight) of the rider+bike+kit is the most important variable. As it is steep, the air restistance at 20km/h is relative low, and the calculation error for that power loss is small. Error of rolling resistance power is also small. Drivetrain loss is typically 3%.

Iexel, have you figured out what metabolism is yet?

I have the feeling you have a mental disorder.

It's a serious question because a recent post of yours demonstrates a complete lack of understanding of what metabolism is.

You have no serious questions :)

Pointing out once again that Pogacar's power output on the plateau de Beille climb was not 7 watts per kilo or anywhere close.

Anyone who believes such numbers has a complete lack of understanding of how the human body works in terms of power output, efficiency or endurance and a how the numbers are derived. Yes, this includes Lantere Rouge.

You have no serious answers.

Tell us what the physiological cap on human power output is then?

Your body can easily produce 1000+ “W of ATP” during exercise.
250 mM per min, 5 L of leg muscle, -57 kJ/mol

Yes, 1000+ watts is produced in a short sprint. That is Anarobic power. For a climb of around 40 minutes that is mostly aerobic.

The problem with these numbers like 7 watts per kilo, or 6.85 which was the number presented by Lanterne Rouge, is that they overestimate power output by about 10-12% sometimes more because they are using a factory calibration programmed into the system to Make you believe your power output is higher than it is. It's a marketing strategy. In reality if you believe such numbers, you are inevitably overestimating metabolic output and underestimating efficiency. This is why the drug worshipers of letrun don't understand why they are wrong.

Jack Daniels submitted his PhD thesis on this subject in 1968. Here we are in 2024 and much of mainstream science has ignored the reality of how oxygen uptake actually works and replaced it with ignorance.

Yeah I had the same question on another thread. Sure, even if we just straight up assume that guys are still doping (they are) but that methods are now more tailored and sophisticated (they almost certainly are), does that translate to over 1km up the road, which is what Pogacar is/was over guys like even Armstrong?

Okay so the equipment is also better - but there are restrictions on this (ie. weight) which as you said, simply translate to that much either.

So still, improved doping practices + marginally better equipment + marginally improved talent - still no way this translates to 10%/an astronomical physical physical difference on these climbs right?

All jokes aside - are these bikes truly legit? When you think of the difference even 30-40W of power for 30min could make and something that could provide this could really be so unobtrusive (don't even think the classic "bottom bracket" but more like wheel hubs, I even remember watching a clip of a guy that designed something that went in the wheel rims and this was 25 years ago - who would ever know?) - either way this must be one of the most fascinating sports to be in the inner workings of.

So all power meter manufactures have conspired to inflate numbers by 10-12% together? I can't understand what you're saying.

You didn't answer the question.

There has been loads of work on exercise metabolism since 1968? No one in the field things 6.1 W/kg (or whatever you are implying) is the limit for 20 min power output. I am confused by what you are implying.

Yes, why would they offer power meters that show a lower, but more accurate output? It makes no sense. They wouldn't sell.

Why did team sky employ an exercise physiologist who wanted to demonstrate accurate, much lower power output numbers? Was that a conspiracy?

6.2 for 40 minutes is reasonable for Pogacar or slightly higher in perect conditions.

You know people measure these things independently right?

I agree with the proviso in the abstract. The variation between different models is to be expected.

How do you reconcile the fact that Jonas Vingegaard confirmed those numbers?

- Yes, I would almost go so far as to say that. The others on the team said that someone has estimated how many watts per kilo we have stepped on. To put it bluntly, it is very accurate.
- Of course I don't know what they drove in the old days, but it's at least the best I've ever driven, says Vingegaard at Monday's press conference.][

i've got a lot of experience in cycling (raced at a high level) and bought my first powermeter in 2003

if wind conditions were identical it would take about 17-18% more power to go 10% faster up a climb that averages 8%.

even considering that cyclists nowadays are leaner (Wetmore would be so proud of Jonas V.) it's unfathomable that the current top guys have a w/kg that is nearly 20% higher.

i can accept they are a little bit stronger that the doped up riders of the past (peloton has never been clean and never will be) but i would bet the house that they had very favorable wind conditions.

17-18% difference in power is very similar to the difference in power between international class men and women.
