Hi guys,

I was researching a lot but found different definitions of Inigo San Millan’s zones. I found the following definitions for the top of Z2:
– VT1
– LT1
– Fatmax
– Fat% = Carbs%
– 75% of HRmax
– dfAlpha = 0.75

Based on my values, that makes totally different zones.

Does anyone know the correct definition of Millan’s zones? Maybe with a source?

Hi Dada,

I’ve only heard Iñigo on the “Peter Attia Drive” and “That Triathlon Show” podcasts where he defines the first inflection point in a lactate curve (with 10 minute stages) as the top of zone 2. It’s not clear to me if he meant it as the first rise in lactate or in a more mathematical sense (where the curvature changes signs). Perhaps the former, much like how Alan Couzens defines AeT?
