Lactate Scientist: Why MOST Runners Get Lactate Threshold WRONG

Most runners train to improve their lactate threshold. But what if improving it is actually making you slower? In this episode, I sit down with Dr. Peter Tran — sports medicine PhD, 1:14 half marathoner, and co-founder of Athyx — to break down everything runners over 40 need to know about lactate, how to actually use it to guide training, and why most of what you've heard about lactate threshold training is wrong.

We also get into fueling strategies, the truth about high carb versus low carb for endurance athletes, and the future of continuous lactate monitoring — including Peter's new wearable device that could change how runners train forever.
