That's true, think he does
What I found interesting is that the current Norwegian national team coach Arild Tveiten seems to train a little bit different than I would have expected according to this podcast: https://scientifictriathlon.com/tts154/
Basically they train a lot of volume, lots of low intensity but the high intensity is not that high because he says that it's a long distance sport so high intensities are not needed as much
My understanding of 80/20 was (from some readings) 80% low, 20% mid and high
But question are :
what is limit low/mid ?
what is limit mid/high ?
Apparently the Arild Tveiten method is
lot of low volume (below 60% max VO2 power) : 70% or 80%?
quite a lot sweetspot (around 68% max VO2 power) : around 25 % ?
very little high intensity (FTP, PMA, and above) : less than 2% ?
The Michael Weiss split for 2018 season, linked above and in another thread is similar :
70 % low
28 % middle (below and slightly above sweetspot)
2% FTP and slightly above
So, it is around 70/28/2 or 80/18/2 methods for low/mid/high ?
Low : base endurance, maxfat zone
Mid : 60% to 70% max VO2 power
High : FTP, and very little PMA
