We put on our space cowboy outfits for this great episode! The main topic centered on the almost-ubiquitous use of higher carb intakes in recent races, from the Canyons 100k to the Boston Marathon to the cycling classics. What once seemed optional is now mandatory. Where do the next breakthroughs come from? We outline some ideas to try to catch the waves before they become obvious.

There was also some fascinating science on warm-weather and metabolic processes, showing reduced carb oxidation rates in heat. That could have big implications for how fueling and GI training changes with harder efforts.

And this one was full of the best topics! Other topics: Megan’s heat suit debut, our current thinking on heat suit guidelines, David’s 50k race, what he is learning approaching Western States, fluid intake, a study on intense PM exercise and sleep, the wild Canyons 100k, Kilian’s fascinating training approach for Western States, a follow-up on the shoes dominating the road scene, the Breaking 4 Project, and putting power in your stride, plus a Q+A on steep vert, Jess McClain’s Boston Marathon training, and fueling from gas stations!

You are all heat champions to us. May you be blessed with the stickiest treadmills.

We love you all! Huzzah!

-Megan and David

Our minds were blown by the Boston Marathon right before recording this great episode! The main topic was a new study on the Puma R3 super-shoe, conducted by a top researcher. It showed a shocking 3% improvement in running economy relative to the previous generation of super-shoes, with a universally positive response among study participants.

We discuss the evolution of the tech, how it was made with the help of optimization algorithms, and what might come next. Running may never be the same, and we don't think people have realized it yet.

We also had some instant reactions to the Boston Marathon! That included Jess McClain running a 2:22 for top American while working a busy job and training with lower volume. We break down some of her training!

And this one was full of amazing topics! Other topics: Boston Marathon thoughts, how carbs are changing the dynamics of road marathons, nose strips, the awesome Coffee Club podcast, an incredible article in Outside Mag by Devin Kelly, Strava's acquisition of AI coaching app Runna, a hilarious post-exercise cooling study, a quick-hitter news rundown, fatigue resistance efforts, how time on feet in your job may change training, resting heart rate variation among people, downhill form, and creatine for endurance athletes.

This one was so fun! Thank you so much for being here.

Let's go girls,

We put sensors in all the right places before this HOT episode! The main discussion was on the emerging science of heat training, centered around a 2025 study that showed 3 x weekly sessions could sustain hematological adaptations from an altitude camp.

Heat training is no longer just about being ready for hot weather. It's about helping our blood be full of oxygen, powering performance in all conditions. We try to take a "no secrets" approach to bring you onto the front lines of The Heat Revolution.

And this one was full of amazing topics! Other topics: Megan's review of a harness that helps with running form, David's review of the Core 2 heat sensor, heat training guidelines that the sensor illuminated, a follow-up on mitochondria protein, protein needs for different workouts, protein powders we like, heat suit training and what it tells us about physiology, whether it's beneficial to know VO2 max numbers, what hardship teaches us, how we try to hold onto those lessons, the best distance to race in a partner v. partner showdown, bathroom breaks in races, and lots more!

Thank you so much for being here! HUZZAH!

May your thermometers be warm and lubricated,

-David and Megan
