I’m glad Hayden’s shoes are legal again!

There’s an easy solution, stay off ST.

Are you talking about G?
I saw Cav walking around town and then he was there at the swim start in the announcers booth.
So everybody pretty much watched these guys run the entire run. What are your estimates on Carbs per hour before the nutrition sponsor starts posting, “180 GRAMS PER HOUR ON THE RUN”?
The bottles they carry instead of gel sachets make it hard but 180 seems fair.
A few things:
-
Many will be lauding the “Norwegian Method” after this. But not really understanding what it’s all about. It’s actually not that complicated A- Build up a massive aerobic base over years and years and years. In Norwegian Nordic Skiing ( another sport they dominate) they target about 1000 hrs/year as the Gold Standard for training volume that they try and build most U23 skiers up to starting in their late Teens. Once a young developing skier has done this, they move on to the next phase. B - Fine tuning the threshold training that best matches up with the Race Intensity that is required. Here a decent amount of science is involved, but it can also be rather simple as well. C - Group training when done right can be very helpful!

Dave Scott queried a few years back, wondering why the run times were not getting faster at IM Races - and now they have. Dave’s rational was all the modern cycling advancements - were yielding not just faster bikes splits but faster bikes splits with less watts - why weren’t those watts savings going into faster runs. While now they are!

Norwegian Sports Culture - They look at Sport VERY differently than in many countries! Sport is celebrated in Norway by a HIGH percentage of the population, and in particular ENDURANCE Sports! Norway’s radically different approach to sports helped it climb to the top of the Olympic podium - The Globe and Mail

Cross posting (thank you @sfjab ) this as some may miss it in that thread. An absolute must watch/listen (best watched as their voices are not that easy to differentiate).
re: #2
The run improvements must be in large part due to the shoes.
Not sure I buy the ‘faster bike splits with fewer watts’ thing unless there are data to support it.
#2:
Bike times havent gotten faster with less watts. They have gotten faster with more watts, with nutrition improving they are able to ride much harder for longer.
I dont have much data, but there is a video from quarq on youtube about Frodenos 2015 Worlds Bikesplit. He did 265w for 4:27. Laidlow famously did 311w for just over 4hours 3 years ago, I suppose numbers up front are even higher now.
That is a huge effort, only possible due to high carb.
This also means more fatigue and therefor no big improvement in run splits even with much faster shoes.
Now everyone stepped up their game through training and they are able to run faster off harder rides, which is only logical with much better equipment and better nutrition.

When everyone was riding at lower watts and more in fat burning mode, I assume then they were riding at a lower percentage of FTP. If Laidlow is riding so much higher watts than Jan Frodeno (off a smaller body than Jan?) was riding in 2015, I assume he’s riding at previous half IM intensities more in carb burning mode…like 85-90% FTP vs 70-75% ?
Saw a GTN interview of Casper … “300w is an easy day”
Correct, and further, it’s the total Work for the bike which has to be determined to be able to draw any conclusions - in @smar example, assuming those are correct data, JF would have expended 4245kJ whereas SL would have expended 4534kJ…not supporting the supposition that there is energy saved for the run.
According to his Strava Activity Kristian expended 5578 KJ this year, which would mean an average of 342w. Thats a lot of energy and a lot of fatigue.
Well unless SL was able to put more calories in during that time, which I think we can all agree is what is happening now that the old 90 grams an hour barrier has been shattered.
Jan is taller, but not by much. The denominator in w/kg is pretty much the same
Sam is 1.89m and 75kg
Jan is 1.94m and 76kg
Or at least that’s what Wikipedia / PTO says

OK so Jan and Sam are roughly the same weight so if Sam rides at a much higher wattage either he is burning way more carbs or his FTP is substantially higher and they are both riding at roughly the same percentage of their bike FTP. I don’t recall Jan ever running sub 2:40 (maybe Roth or the smackdown with Lionel) which Sam just did at a Nice so maybe Sam just has a higher threshold than Jan in all sports however Jan was a lot older and his thresholds would already have dropped and Sam’s will too
Dev - why don’t you check this before excusing your memory?
Frodeno Hamburg 2023 - 2:38
And Frankfurt and Roth.

Did you get your Sam’s mixed up.,thought we were talking about Sam Laidlow. He ran 2;42+ this past weekend…

You are correct. I got the splits for the two Sams mixed up. In any case is Sam Laidlow’s bike FTP higher than Jan or is he just burning a ton more carbs than Jan used to
