Iñigo San Millán training model

[bbarrera]

On this again:

@bbarrera

Depending on the level of fitness of an individual, and up to 55-75% of VO2max intensity, ATP synthesis (energy) is generated from fat and carbohydrates

That is a direct quote from San Millan, not me:

not following the point you are making. Are you saying San Millan is wrong?

@sryke

He definitely does not mean zone 2 with the given range

San Millan’s zone 2 from a TrainingPeaks blog post:

Therefore zone2 is NOT below Aerobic Threshold (Coggan’s zone 1, or Seiler’s zone 1), where the energy substrate is predominantly fat.

Those zones sure look a lot like Coggan levels, where tempo / level 3 efforts involve enough force that Type IIa fibers become more actively involved with energy production. And where threshold / level 4 efforts require significant energy production from carbs.

@sryke

As already pointed out in the other thread, the following structure (as given in the TP article) appears from his Strava:

An endurance athlete should never stop training in zone 2. The ideal training plan should include 3-4 days a week of zone 2 training in the first 2-3 months of pre-season training, followed by 2-3 days a week as the season gets closer and 2 days of maintenance once the season is in full blown.

As San Millan stated in another TP blog post, Fitzgerald’s 80/20 rule, Friel’s periodization recommendations, what I see in Carmichael’s plans, what I see in FasCat plans, etc., etc. And San Millan goes further and points out you also need to train glycolytic capacity, as the two go hand in hand in improving lactate clearance.

I’m guessing its fair to say we agree the science is pretty clear and largely in agreement. Now take that science and go look at TrainerRoad’s high-volume sweet spot base plan. What do you see?
