We had some HYPOTHESES for this amazing episode! The main topics all revolved around fatigue resistance (often called “durability” in the literature), which we think is the most exciting area of training theory and physiology. It started with Rachel Entrekin’s legendary overall win at the Cocodona 250, an event that explores some of the strangest and coolest parts of endurance.

Our big theory: what we’re seeing in these wild ultras is directly connected to what we see in short distances. A new study looked at fatigue resistance variations between men and women, with some shocking results. We expand the scope to talk about the literature generally before going to some ideas for how it all might relate to the central nervous system.

...And how it relates to fueling. You could probably guess that we were going to talk about carbs.

Plus, we answer questions about the culture of fueling for young athletes and feeling good after long runs!

This one starts with a description of Megan’s health journey. The hottest vacation is apparently a 3-day stay in Boulder Community Hospital. Things are scary, but we’re holding onto hope for the future.

We love you all! HUZZAH!

We violated the warranty on ankle tape before this great episode! A main topic involved taking a step back to understand the historic context of Vinny Mauri’s 2:05 debut marathon. We think it’s a performance that signals a fundamental shift in the future of the sport for everyone, and we discuss why.

We also talked about the exciting news that Jim Walmsley is heading to Western States with a sponsor slot. The GOAT is back! David had some terrible hot takes, and he’s now panicking that he didn’t give enough disclaimers that he doesn’t actually believe any of them.

And this one had lots of fun topics! Other topics: unique uses of athletic tape, Abby Steiner sues Puma over their shoes, misconceptions about training volume, physiological testing of private parts, uninformed thoughts on the Kentucky Derby, a hydration review arguing that many athletes underhydrate outside of training, a study on ketones during hard efforts, using caffeine to increase heart rate, combining Nomio and bicarb, the wild world of zone compression, AI thoughts, and lots more.

To us, you are all in the top 1%. That will make sense after you listen. Unfortunately.

We love you all! HUZZAH!

We made an unfortunate impulse purchase (you'll see) before this great episode! The main topic revolved around the world records at the London Marathon, including Sebastian Sawe’s 1:59:30 winning time. We discuss his mid-race fueling, bicarb use, shoes, and so much more.

Plus, there was an important study measuring the differences in mechanical output between sprints, strides, and plyometrics. This study could be the missing link that identifies why strides are such a ubiquitous part of elite training approaches.

And there were tons of fun topics! Other topics: the purchase David is not proud of, a game theory hypothetical, a high-carb case study, the amazing Women’s Gear Index, luxury gear, an existential question on life and training, a potential treadmill study, barefoot shoes, iron dosing theories, and lots more.

Come for the carb talk, stay for the knowledge that David will occasionally have the worst takes you have ever heard. We take back every thought we head about pressing the red button.

We love you all! HUZZAH!
