We brought some very sore legs into this great episode! The main topic was a new study on "Zone 2 Training," which gathered a panel of experts to review what Zone 2 means and why it matters. Our theory is that Zone 2 training is interacting with high-carb fueling to drive some of the performance revolution!We also talked about a new study on heat training. It shows that heat-induced adaptations and fitness improvements seem to mimic one another, but may come from different sources. Thus, stacking them could lead to outsized benefits!And get a big plate because there was a buffet of great topics! Other topics: leg soreness from downhill running, a follow-up study on trail supershoes, whether athletes without supershoes will be at a disadvantage on trails, weird heart rate zones, weird blood lactate curves, how athletes can vary from population averages, how we try to embrace pressure, pre-workout carbs, going for it at Western States, uphill treadmill workouts, feel v. metrics in harder workouts, joy in dark forests, and peeing in races.The hottest soundtrack in the club is going to be made up of the whale songs on this episode. Drop it like it's waaoaoooooooooooaoaoo.We love you all!
