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

  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!

• 254. How Heat Training is Changing the Game, Protein Needs for Endurance, VO2 Max Numbers, Workout Success v. "Failure," and What Comes After Disaster!

  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!

• 253. New Science on Protein Needs, Unbreakable 2, VO2 Max Estimates, Carb Loads, Torpedo Bats, and Cross Training Intensity!

  We put on our finest white spandex for this amazing episode! The main topic was a new review study on protein needs for endurance athletes. The authors used a cool method of isotope labeling to argue that endurance athletes need more protein than traditional recommendations. The nutrition revolution is not just about carbs! And this one was full of great topics! Other topics: the announcement of an Unbreakable 2 documentary heading into Western States, Kilian Jornet's sustained dominance since the first Unbreakable was filmed, the 1-year anniversary of the bike crash, Tailwind High-Carb, our questions about protein recommendations, increased power and weight in professional cycling, torpedo bats dominating the conversation in baseball, mile times of the Houston basketball team, VO2 max estimates from your watch across different sports, nutrition on race week, the "yips" in running, balancing intensity with cross training, maintaining confidence when changing jobs, overdressed walking for heat training, and balancing training with studying for the bar exam.Thank you so much for being here in the year since the accident. Showing up each week has been a backbone of our lives, and we appreciate you so much. Florence and the Machine can play us out:"Is this how it is?Is this how it's always been?To exist in the face of suffering and deathAnd somehow, still keep singing."We love you all!

• 252. How Running May Impact The Brain, Plus Q+A on Body Image, Heat Suits, Sweat Testing, and Nose Breathing!

  We pondered the genetics of smelling ants before this great episode! The main topic was a new study that found the brain may use myelin lipids for fuel during low glucose conditions like marathons. This could have massive implications for how we think about fueling and fatigue resistance, including for cognitive function. Our big theory: fueling is just as much about nourishing and protecting the brain as it is the legs.And this one was full of amazing topics! Other topics: the resurrection of the green shorts, “tension” training via uphill biking and running, heat suit training, genetic data, why post-exercise ketones may be most beneficial after longer efforts, the wild connections between heat response and evolution, body image and clothing choices, heart rate after layoffs, racing athletes we coach, dealing with break-ups, the art of sweat testing, and our frustration with nose-breathing recommendations.May your shorts be green and long,-Megan and DavidClick "Claim Reward" for free credit at The Feed here: thefeed.com/swap Buy Janji's amazing gear: https://janji.com/ (code "SWAP")For weekly bonus podcasts, articles, and videos: patreon.com/swap

• 251. Big Alta 50k and The Story Athletes Rarely Tell, Plus Q+A on Kilian to Western States, Bike v. Treadmill, and Sauna v. Hot Tub!

  We took off our armor for this incredible episode! The main discussion might have been one of our most important (and fun) ever: the Big Alta 50k DNF, failure, and what it truly means to go for it. David raced Big Alta because it was somewhere that he couldn't hide. We needed to gather data about what happened at the very edge of human capabilities. And when you F around...sometimes you find out. We hope that you feel a connection to your big scary dreams. Thank you for giving us the courage to dream bigger!And this one was full of great topics! Other topics: racing lessons from Big Alta, why ankles are annoying, guys v. dudes, running your own race, Jim Walmsley dominates at Chianti, Kilian is going to Western States, sauna v. hot tub, going from 0 to 1 to 2 kids, running groups, bike v. treadmill, core work, life "balance" for people with big goals, long-term training builds, and lots more.This episode gives you a raw window into the true story that athletes rarely tell. We all fail. Life really unfolds in what happens next. We love you all!
