194. World Record Training Study, Heart Rate Monitors, Sports Bras, Iron and Lactate, and AI Thoughts!

We glugged some sugar with coffee and cream for this awesome episode! The main training topic was a new study breaking down the training of the 24-hour world-record holder. It gave us an excuse to talk about the trajectory of ultra training, and how we're in the midst of a fundamental shift in the sport at all levels.

We also talked about a cool study on sports bra tightness and breathing patterns. The results were pretty stunning, and it may have implications for chest-strap heart rate monitors too. Plus, the researchers gave us the chance for lots of bra jokes. Not all heroes wear capes. Some wear sports bras that are just the right size.

And that was just the tip of a topics iceberg! Other topics: early morning wake-ups, our initial thoughts on arm-band heart rate, Megan's thoughts of stepping into the unknown at the Canyons 100k, a study on iron infusions that has implications for how we think about iron and lactate transport, a follow-up on last week's THC discussion, the U.S. Snowshoe Championships...without any snow, drug testing and compassion, recent breakthroughs in AI and where we think it's going, a typo that will make you feel better about your mistakes, and hot takes.

Stick around to the end, because the episode ends with a listener corner that will have you glugging from a fire hose of inspiration!
