We celebrated huge beating genius machines before this awesome episode! The main training topic was on 10 ways our training approaches changed for Leadville and Javelina. Throughout the process of preparing for 100 miles, we made itty bitty alterations that sometimes became big shifts in how our plans usually look. We break down each of them and how they might apply to other athletes. Time to pop a squat (or 2 x 10 reps of them). Before that, we have a little love letter to listeners. That...

We answered tons of amazing listener questions on this great episode! We approached Leadville and Javelina like science experiments, and like all good science experiments, we want to share everything before starting a new experiment for the Western States 100. This one is full of sexy science, theory, psychology, nutrition, and so much more! Our philosophy is "no secrets"... sometimes to a fault. That means spilling the beans on everything from training to nutrition to gear, plus some hot...

We ventured into the unknown at the Javelina 100 Mile, and we're coming back with a celebration to share! This episode is all about processing a life-changing weekend where David won Javelina in 12 hours, 45 minutes to earn a Golden Ticket to the Western States 100. There was one defining feature of the day: HEAT. Race day featured record temperatures around 100 degrees F in Phoenix, with the course traversing desert cactus that didn't offer a hint of shade. Given the short training time...

We reached deep into the BELIEVE BAG before this great episode! It started out with all of our thoughts ahead of the Javelina 100 Miler this weekend. This journey into the unknown has it all: fears, dread, and doubt right alongside excitement, celebration, and DMX. We hope this exploration gives you a tailwind that pushes you to chase scary dreams. We also did a deep dive into a massive new meta-regression study on mitochondria and capillary development. The study gathered data from...

We put on all of our pants and jackets to record this HOT episode! The main training topic is on the wild science of heat suit training. In 2021, a case study revealed that simply wearing a couple layers while doing easy biking could rapidly expand hemoglobin mass, which could improve performance in all conditions. Numerous other studies support the findings, and now heat suits are a staple of pro cycling training. This could be a new frontier of performance! We talk about how our feelings...

We made loud grunting noises to celebrate recording this great episode! A primary training discussion was on putting the finishing touches on the quick build for the Javelina 100 Miler. It's getting very, very real. Confidence is rising, and falling, and falling some more, then rising again. We bring you into the process to feel just how hard it all can be at times for athletes of all levels. Prepare to grunt. But the main topic ventured into an area we usually avoid: heated debates. A...

We loaded up on some "awake" tea to feel extra caffeinated for this spicy episode! Listeners send in such great questions, and it was so fun to get down and dirty with some fascinating topics. It's called a "no secrets" Q+A because we often see conversations with elite athletes and coaches where it's clear that we aren't getting the full picture. Our goal is to be an open book (for better and for worse!). As a result, this one was full of the most fun topics! A list of some of the topics:...

We marveled at the athletic performance of the year to prepare for this great episode! It kicked off with us picking our jaws up off the floor, in awe of Tara Dower's overall record on the Appalachian Trail. Coach Megan delves into what made it possible (strides and speed) and what sets Tara apart (being a superhero). This achievement will take decades to fully process! The main science talk was a new study on Kilian Jornet's physiology data from 2022 UTMB, where he won in historic fashion....

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...

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,...

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...

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...

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...

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...

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...

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...

We had a party with our insect friends before recording this great episode! A big topic was answering a listener question on how to use heart rate zones in practice when the data can seem so noisy. We think that calibrating effort is incredibly helpful for athletes... as long as they keep it simple. We break down what that looks like! Plus, we tried something new in this episode with a segment called "Hot News" near the start. This week, it included Tadej Pogacar's remarkable Tour de France...

Our GPS watches told us we were "Peaking" for this great episode! The main topic was inspiration from the Hardrock 100. Ludovic Pommeret won just before his 49th birthday, setting a course record in the process, redefining what's possible with age. Courtney Dauwalter set her 3rd consecutive course record, once again proving that she's the GOAT. We talk about how athletes should think about training for steep uphills and downhills, along with lessons for everyone from the record-setting era...

We took some Big Leadville Energy into this great episode! The main topic was the Silver Rush 50 Miler, which David raced on Saturday. The last few months have been a doozy, starting with the bike accident and severe concussion back in early April. It has been hard at times, in ways that go a lot deeper than athletics. This episode is about falling, and the power to GET. BACK. UP. The 50 Miler was David's best ultra yet, and it possibly sets up a date with destiny at the Leadville 100 in...

We were flying high after the best sports week of all time for this amazing episode! The main topic was the 2024 Western States 100, the most insane race we have ever seen. It was not a cool year, but the times were wildly faster across the board, building on massive speed breakthroughs from 2023. What are we seeing? The same trends are present on the track and even in other endurance sports. We have theories! The biggest, most exciting question of all: where might this trend be going next?...

We are coming to you from Eugene, Oregon at the Olympic Track Trials for this amazing episode! The main topic was on some inspiring stories from the first half of the Trials, which feels like the ultimate party of the US running world. And like most good parties, it features a lot of Snoop Dogg. We also talked about lessons from Broken Arrow, including Jim Walmsley doing the Vertical Kilometer race prior to the Western States 100, right alongside Anna Gibson racing the VK prior to the...

We thought long and hard about alien physiology before recording this great episode! The main topic was a wildly cool wrinkle in training science. Across all different types of events, the most predictive variable for performance is often how fast an athlete can go at VO2 max effort. That could have massive implications for how we think about training and what we consider "specificity" for long events! We discussed why we think that is, along with workout designs, the use of hills, and how...

We put on some bouncy shoes for optimal energy return before this great episode! The main training discussion was a new study on a speed protocol that caused major improvements in high-level runners. We zoom out to discuss other studies that have similar findings, including one that provided a theory for mechanisms in slow-twitch muscle fibers. There is one thing almost every endurance athlete should be doing--short speed/hill repeats under 30 seconds. It's wild how simple it can be! Before...

We were emotionally hardened by some sleepless nights before recording this special episode! A couple months ago, a brilliant podcast listener on Reddit published her predictions that Spring Energy's Awesomesauce gel had incorrect calorie counts. Three weeks ago, those findings were confirmed by a German lab. This past week, everything exploded on social media with all of Spring's gels listing fraudulent calorie totals, roping us into a situation that we never hope to relive. This episode...
