  • 257. "No Secrets" Q+A on Extreme Carb Totals (200 g/hr!), Minimum Dose Heat Training, Sodium Intake, Speed for Ultras, and Hydration Sensors!
    May 6 2025

    Our favorite episodes are these Q+As where we answer listener questions on all of the hottest topics! It's called a "No Secrets" Q+A because we try to take you behind the curtain, speculating about ideas that might not be talked about in public very often. Let's get spicy!

    The main topic was Cam Wurf's reported 200 grams of carbs per hour at Ironman Texas to set a bike split record. These extreme carb totals are starting to become more prevalent in triathlon. Do we think they're here to stay? Surprisingly, we have doubts. Forgive us, carb daddy, for we have sinned.

    And there were so many great topics! Other topics: heat suit long runs, race week thoughts, our new favorite recovery product, our initial thoughts on the Nix hydration biosensor, high carb and GI concerns, minimum dose heat training, AI titles, sodium intake during training and racing, kids and hydration, track and speed training for ultras, 2nd opinions in medical settings, working through low motivation and mental health struggles, structuring training camps, and more.

    May your quails be peaceful and your critics get a minor case of plantar fasciitis. We love you all! HUZZAH!

    -David and Megan

  • 256. High Carb Domination, Steep Races and Vert, Heat Suit Guidelines, Increasing Stride Power, and Kilian’s Western States Prep!
    Apr 29 2025

    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!

  • 255. The Shocking Shoe Study That Changes Everything, Boston Marathon Reactions, Creatine for Endurance, and Resting Heart Rate!
    Apr 22 2025

    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,
