LT2 Brain Drain

Lactate Threshold is lactate threshold. There is not a second lactate threshold. Critical power, which is questionable in it's own right, is confused as a second lactate threshold. Lactate threshold can't be identified by any prescribed 2 mmol or 4 mmol power. The conviction that there's this higher level limit or ceiling and training toward that intensity is the reason why there's so much injury, burnout, misery, unpredictable performance and tears in endurance sport. Turns out that when you train harder than is actually productive, it's overtraining, no matter what the group think leads you to believe.
