Of course I take in to account that the riders have climbed already at a certain pace before. But I do cap the maximum adjustment for that at some point and the way I do it is not completely scientifc. The uncertainty and the effort required also go way up if you start segmenting a lot, so I...

I have segmented some climbs of course. As I said, unless it is a monumental attack, the Index for the whole climb is almost always higher than just for the attack. Exceptions for this are for example Vingegaard on Tourmalet in 2023 and Pogacar on Foscagno in 2024. On first glance, Contador's...

Yes, the attack looked quite strong. But unless it is a monumental attack, I normally only analyze the whole climb and the pacing on Etna is always pedestrian.

Thanks to your question @Ulle97 I have finally been able to motivate myself enough to analyze all the Giro ascensions on Etna since 2011. The reason I hesitated so long is that I knew there had never been a great performance and that they literally use a different side of the mountain every...

This comment referred to the specific example of Indurain's hour record, were all the parameters are known (approximately). For climbing efforts, I use 60kg standard weight for all calculations. I also use era-adjusted standard CdA and CRR for every rider based roughly on an average 60 kg rider...

For the 2012 Tour, it is Nibali with 67.3, same as Wiggins. Vuelta 23: Ayuso 78.3, but Mas aand Landa are very close Every formula can be solved if there is just 1 unknown variable. The location and date are known, so the weather data (air pressure) can be looked up. The speed is known. If the...

Normally it is easy to see who the best climber is in a race just by watching it. My Index is also not perfect to analyze this since riders often don't go all out or have 3 good performances but collapse later. It also weighs short climbs the same as long ones. Here is the average of the top 3...

The Itzulia TT was around 7w/kg for 15 minutes, though this was not the finish yet. very good, but nowhere near 7.4+ w/kg for 20 minutes. The numbers I have for the Dauphine prologue are so bad that they are almost unrealistic. Either I have the wrong segment, or the hairpins are messing with...

Do you know the location? Madrid? is at 700 meters.

The best 20 minute effort I have for Nibali is Verbier (6.54 W/kg for 21:43), so 6.9 for 20 under perfect conditions does not seem impossible. For Contador: His style is also not aerodynamic, especially in a pure power test he probably stood on the pedals a lot. I recently tried to calculate...

The pool of riders who can do good w/kg completely fresh is much greater than the pool of rider who can do it in a normal race situation (which are basically the successfull riders). I can see in my data that many riders who have never won anything (much) have their climbing PB in MTTs, while...

An additional point I wanted to mention: I started this work maybe half a year ago, and I am happy enough with my results that I feel comfortable posting them on this forum. But I still make slight adjustments to my general method and also to specific climbs from time to time. Especially if a...

Of course the circumstances were not bad for a high performance, but absolutely nothing compared to Blatten which was almost better for performance than a pure MTT. Adam Yates | 88 (-9): 7.12 W/kg for 19:31 on Blatten R.I.P. (Suisse 2024) Almeida had slightly worse watts due to draft...

Pogacar clearly did a suboptimal climb with Belgium pacing slowly at the beginning. Absolutely nuking the bottom like Seixas is not optimal either. Seixas also lost a bit of time in the flatter section with Jorgenson in the wheel. Irregular climbs like this are seldom paced consistently, which...

There is not much downhill (maybe 3-6 m), but even (false) flats slightly increase the necessary watts to achieve certain VAM and also affect the pacing of the rider (higher normalized watts). My own adjustment for this climb is around 0.1 w/kg compared to a more regular climb. The gaps are...
