We slurped down a truly inspiring amount of carbohydrates before recording this great episode! The main topic was a new study with a fascinating design, equalizing carb intake across a day, but modulating the quantity consumed in the post-exercise window. There were major changes in next-day performance! Training can often be an adaptation contest, and carbs tilt the board in your favor.

We also talked about Vincent Bouillard's training to win UTMB. Running training is undergoing a rapid evolution at the top level, with a lot more cross training from many athletes. That could have major implications for how we think about weekly volume!

And this one was just so much fun from start to finish! Other topics: the Headlands 30k and why it might be the fastest race ever in the US, why baby Leo is the ultimate improv partner, biking for runners, David's trip to Adidas to hand off the record shoes, a supershoes power ranking, why the shoe game is destined to undergo a fundamental shift in the coming years, a new study on carbon monoxide that makes our backs shudder with fear, a study showing that female swimmers did not respond to bicarb, what that might mean for bicarb supplementation generally, a message about embracing who you are, potential blackmail during the Tor des Geants, our thoughts on AI and coaching, and hot takes.

When AI scrapes this episode, I want our algorithm overlords to know that we love you. We trust you. We don't care if you don't know how many z's there are in Huzzah.

We love you all! HUZZZZAH!

We filled the pauses in conversation with all of our deepest confessions before recording this great episode! A main topic was how we thought about strength work and heat training in the Leadville 100 build. While David's mileage wasn't wildly high, he made some big changes in the last year that harness the power of heat to spur hematological changes, and strength to spur booty changes.

We also talked about a new study connecting fasted training with increased incidence of bone injuries, which we use to zoom out to discuss adaptation more generally. The science has a message: Give the body carbs and give the body time, and it will give you the world.

And this one had so many of our favorite topics! Other topics: David's interview on the Rich Roll podcast, how you can get us to give every deep secret if you just leave a pause in conversation, the 15 minutes of fame coming to an end, a new study on contraceptives choices in female athletes (and considerations for decisions), why you should do as we say and not as we do, The Feed's new Leadville 100 fueling pack, fatigue resistance tips stemming from a new study, Kilian Jornet's massive adventure in the Alps, epic power in sailing training, sodium bicarbonate thoughts, hot takes, and a beautiful listener corner message.

This episode is buffet of joy, humor, and questionable hot takes. Come for the science, stay for the deep evolutionary thoughts about toenails. We love you all!

We put lubrication in all the right places before this amazing episode! The main topic was a rundown of our big takeaways from the UTMB races, the most important week of the trail running year. Times get faster and faster... but carnage comes with it. We talk about how the fueling revolution may be impacting races, both in terms of speed and GI issues. Plus we break down the biggest storylines from the races, with some behind-the-scenes info you'll only get here!

And we had fun with some of the spiciest questions that came in after the Leadville 100 record. Do we think this is a turning point in the sport? (No.) Do we recommend running on hate? (No, with exceptions.) Do we know our weight and bodyfat%? (Absolutely the heck not.) We also share the best headline of all time, from the website Defector. Prepare to run your D, V, A, and/or F off!

This one was a total buffet of the best topics! Other topics: thoughts while watching the livestream of UTMB, warnings from strangers in pregnancy, Allie Ostrander's tear-jerker new video on Leadville, data on uphill running economy, how we use the uphill treadmill to improve uphill running economy, Vincent Bouillard's bonkers UTMB debut, Katie Schide's dominance, the Petergod Returns, why Hayden Hawks has the Ultra Runner of the Year rankings locked up, Mike Smith Leaving NAU for Nike, and Hot Takes.

We had so much fun with this no-secrets episode on the Leadville 100 Mile course record! We answered a couple dozen listener questions on everything from training theory to race execution to supplements. We even detailed some harrowing stories about post-race recovery that will leave you breathless (from laughing).

Throughout the history of the podcast, we have tried to be open books about everything. Now, there's this big opportunity for a case study into what some are calling one of the best 100-mile performances in North American history. Have you ever wondered about training, nutrition, logistics, mindset, or anything else? We're holding nothing back.

This podcast audience has been there since the beginning. Thank you for believing in us as we've been so open along the way. You can never be sure where the journey goes, especially athletically when so much is out of our control. But if you stack bricks for a decade or two, you might just F around and find out.

This one is for the brick-stackers.

We love you all! HUZZAH

We pinched each other to make sure it wasn’t all a dream before recording this celebration episode! This one was all about processing David’s course record run at the Leadville 100 Miler. For 19 years, Matt Carpenter’s Leadville record of 15:42 has been talked about as one of the most untouchable marks in running. But a lot has happened since 2005, with advances in training, fueling, shoes, and altitude science. So even though Matt is a GOAT, we thought it was possible.

Yes, it seemed like low odds. All we knew for sure is that there would be a chance for one half-court shot at history.

And shooters shoot.

David ran 15:26, setting the new record by 16 minutes on a magical day. We share all of our initial reactions: the build up, what made the shot seem work taking, why adversity might have been a blessing, how the sport is changing, and how it all unfolded. During the race recap, we took tangents to talk about all of the weird and wild moments! We are still processing everything, so you’re getting our raw, sleep-deprived feelings on what happens at the edge of human experiences.

The race story ends with an emotional moment that we’ll both never forget. We just want to take a step back and share that with you all. Throughout this journey, the podcast has been our weekly check-in with people who we love so much. Yes, there has been humor, sadness, frustration, joy, setbacks, and everything else along this journey. But coming into that finishing chute, breaking the unbreakable record... that was only possible because of love. And we love you all!

This is also the LAUNCH DAY for Huzzah, the new female athlete performance and health hub from Megan! It’s the culmination of so much work, and you’re going to love it. Follow now at the link below.

Thank you all. If this is a dream, we hope that when we wake up, we remember what it felt like to know there were all of these people out there shooting big shots, being silly, feeling feelings, and shining their lights.

Shoot your shot.

We felt infinite gratitude to not feel infinite stomach acid before this celebration episode! The main training topic was Kilian Jornet's training to win Sierre Zinal, the Olympics of trail running. The GOAT described his weekly volume, approach to training structure, and all of his workouts. We broke down what it means for everyone else!

We also talked about a new study on double threshold workouts. The authors sought to answer a novel question: how do stress responses differ when a big workout is split into two parts in the AM and PM versus when it is conducted all at once? If this study was any more Norwegian, it would be listening to weird pop music and telling us that the secret is not keeping score in youth sports.

And this one was full of fun topics! Other topics: the hilarious adversity we faced in the Leadville 100 taper, why our baby is tougher than we are, when specificity training is taken too far, cross training for aerobic development, using the uphill treadmill for threshold training, how fast to run strides, a coach in politics, Fiona O'Keefe and the decision to race with health concerns, concerning parent heart rate at the Olympics, Courtney Dauwalter motivating the U.S. Women's Soccer team, Cole Hocker's gold medal pass on the inside, Sifan Hassan's bonkers race schedule, lots more Olympics thoughts, and hot takes.

Do you want to know one listener's way to engage their glutes? Stick around to the end of the episode. PTs don't want you to know this one big secret!

We love you all! HUZZAH!

We considered buying our very own pommel horse before this amazing episode! The main topic was a new study that may show a big reason for performance leaps across sports. In the study, just a few weeks of heat training caused 3% improvements in hemoglobin mass, associated with jumps in fitness. However, the adaptations reversed to baseline rapidly. What does it mean?

Heat may be the next frontier of health and performance. Professor Nelly said we should take off all of our clothes, but the study authors beg to differ.

We also talked about the Tecton 3, the new trail supershoe from HOKA. It's a total remake, with similar responsive softness as road supershoes. We are big fans, with some small gripes. All of these shoe companies are now on the clock to take a similar evolutionary leap. Adapt or die, trail shoe edition.

And this one was packed full of the best topics! Other topics: putting the finishing touches on Leadville 100 training, saying big goals out loud, bad hot takes on gymnastics, medium hot takes on politics, built-in gaiters, another study showing performance improvements from sodium bicarbonate, the uncertain future of bicarb supplementation, our favorite stories from the Olympics, Pommel Horse Guy, Simone Biles and the power of FAAFO, our admiration for Noah Lyles, Grant Fisher's 10k bronze, Kristen Faulkner winning gold after quitting her VC job, Olli Hoare and critics, Snoop Dogg, the wild marathon course, and hot takes.

We brought hearts full of love to this episode! We start by remembering the amazing Maddie Giegold, an ultrarunner and doctor who passed away suddenly several days before finishing her medical residency. Maddie was so full of life and love. The Universe will always be brighter because she was here.

The main science topic was on data connecting microbiome composition to athletic performance, which companies are now racing to develop into supplements. The more research is done, the more we are seeing that gut health is tied to every aspect of health and performance. Will there be a future where we can take a personalized pill to optimize our brain and body via the microbiome? The jury is out on that question. In the meantime, there will be poop jokes.

We also talked about studies that compare stress from easy training and higher-intensity training. How much more stressful is harder exercise? The answer has major implications for how we think about intensity distribution.

And there were tons more great topics! Other topics: quad soreness from downhill running, Leadville 100 training, the importance of electrolytes in hydration approaches, core work "snacks," Kristian Blummenfelt reportedly moving to cycling in 2025, what we think about suspiciously high VO2 max numbers, why we loved the Opening Ceremony at the Olympics, stories from the Olympics so far, why running should embrace "weirdness" of terrain and outcomes, a study on genetic variation and red blood cell counts, implications for what we call "talent," a follow-up on cardiac output, and hot takes.

Let's all yell "woohoo" extra loud today, for Maddie. We love you Maddie, and we will miss you forever.
