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?

The maximum amount of oxygen your body can use under load: the single best-studied marker of cardiovascular fitness. VO2 Max Test, $275.
VO2 max is the size of your engine. Why it matters, why bodyweight, strength and an aerobic base come first, and the workouts that develop it.
You do not need to know your VO2 max to improve it. Gareth uses the test for fuel mix, and only after lactate has set the zones.
Zone 2 is low-intensity cardio that builds your aerobic base. Its benefits, how to find your Zone 2, and how often to train in it.
One hour in the lab in Santa Monica, and you’ll know exactly how your body produces energy, and precisely how hard to go.
