Why is it that some endurance athletes don’t burn much if any fat even though they train for long distance events such as the marathon or IRONMAN. Furthermore, how come they can have low lactate (sub 2mmol) when cycling or running in “zone 2” BUT don’t burn much if any fat (circa 20%) where others burn 80%+ fat in this zone?

VO2 max is the maximum oxygen your body can use under load — the best-studied marker of cardiovascular fitness. How we measure it in Santa Monica.
Zone 2 is genuinely easy aerobic work, bounded by your aerobic threshold — not a formula from your age. How a lactate test sets it.
A blood lactate test finds the intensities where your training zones actually begin and end. How the protocol works in Santa Monica.
One hour in the lab in Santa Monica, and you’ll know exactly how your body produces energy — and precisely how hard to go.
