# Zwift=One big sprint

NICE JOKE.
ITT specialist is always faster than climber.
If it is the same PWR in Zwift, it always drives fast heavy one.
Zwift can invalidate the torque up by the climb, mountain is the flat ground that an avatar only slowly.

Even if it is Ven-top even if it is AdZ, Zwift is no place of the climber.

You made this statement a few times. Do you have examples to back this theory? Zwift is based on IRL formulas to calculate speed from power taking various factors into account.

Zwift incider inspected it.

I think you mean that for the same w/kg in Zwift, the heavier rider goes faster. This is true except on substantial hills, because for the same w/kg a heavier rider (more kg) puts out more power (more watts) and therefore goes faster.

@Blue1 no that was not his conclusion. if we are talking about the same article. He made a case that w/kg categories is not the best option because it ended up being weight classes.

What you suggested is that heavier riders are always faster even on a climb and that is not true.

w/kg ratio is used IRL to compare riders climbing abilities. it was never meant for racing categories. But we as a community started using it because it was an easy metric to put in a spreadsheet so that we can have some competitive racing.

Zwift should have adopted a race ranking system years ago.

See here:

Zwift is the one and only place where a climber who put 265W can beat Alex Dowsett putting 100W more…

If you think a climber suffer on the flat at Zwift, OMG, I figure how hard have to be real life for you… I’m sorry

That link you posted has so many things wrong it is not even funny.

You liked that post so many times but the post is still incorrect.

I have a hard time seeing how a sprinter would take you down on Alpe Du Zwift or VEN, well if another cyclist is at just the last turn when you are there then sure he can sprint so hard he falls off the damn mountain but otherwise I have a hard time seeing how his sprintingpower would take you down? But that would be some kind of combo of a sprinter and a climber. I hope you don’t consider someone’s power for 30 minutes as a sprint. Hehe

Well, sure all of you have seen Wout Van Aert climbing with the best (or doing it better) in every classic and even doing it at the last climb in the hardest stage at the thrid week of the Tour of France.

Also Rohan Dennis did it in the Giro at Stelvio.

And sure the older can remember Miguel Indurain crushing pure climbers as Pantani, Chiapucci…etc.

There are some myths around there about “light climbers” and real performance. Should be revisited.

Because X climber was faster than the professional rider who cycle lightly, is a X climber superior in ITT?

NICE JOKE!lol

And please hear the reason why Zwiftfpower added wattage category to in Zwiftfpower forum.

TT specialist is not a sprinter.

The one thing the Zwiftinsider did not show is the difference in power.

What you can see is for 4w/kg
65kg = 39.8km/h @ 260w
100kg = 43km/h @ 400w

That 100kg guy has to do 140w more for 3.4km/h

TRUE!
Has to put 53% more power, but for sure their lungs and heart are not 53% bigger…

and as I told you many times before, in real life 140W more… will be a bigger speed difference.
Hope you can ask more people or try yourself.
Zwift model penalize too much the big guys.

We are all racing in Zwift so the same formula hold for all riders. We are not trying to race IRL riders.

we have discussed this before and still no proof.

The small guys say it is easy for big guys and the big guys say it is easy for small guys.

It’s the Wild West unless everybody is honest and using the same setups … which isn’t practical other than in a controlled race environment that puts everyone in the same place on the same equipment and all are weighed/measured at signup. The ‘honor system’ isn’t being followed by everyone, so I gave up caring about results and just ride to get me through long Winters and offset the side effects of beer consumption.

There is not the 0.1t fatty in a winners’ platform if I talk about the real world.

Sure you will loose in real world against that fatty you say… so I’m sorry.
But maybe there are 190cm tall, full muscle people with 85-88kg that will win in the most of races in the real world against the light 60kg guys… as cycling is more than Alpes and tour of France.

Maybe running in the mountains, trail…etc lighter is always better. Not cycling… Somebody had to tell…

Really “fresh” article!
