316. Why Western States 100 Records Are Getting Smashed, Z1 v. Z2 Training, AI Coaching News, and Competitiveness v. Ego!

It’s the best time of the year, and we brought that energy into this great episode! We started by bringing out our big predictions and hot takes for the Western States 100. The hottest take: everything about our understanding of endurance physiology is going to change on Saturday. We tell you why. We also talked about a new study asking a fascinating question: does the intensity of easy training matter for adaptations? The answer: not really, if overall stress is equalized. Our main conclusion is that no pace is too slow for aerobic development.  And this one was full of awesome topics! Other topics: switching heart rate monitors with a training partner, our complex thoughts on AI coaching, AI body scans, new data on trail supershoes crowning a possible champion, the perils of optimization based on studies, a cool study on human-wildlife conflict, competitiveness v. ego, burping in races, and a beautiful Listener Corner message.  Whenever you’re having a bad day, remember: there might be a thicc zebra waiting for you on the carousel of life. We love you all! HUZZAH!
