We got extremely hyped watching the Boston Marathon before recording this amazing episode! The main training topic was a new study connecting carb intake during exercise to reduced central fatigue, leading to the researchers theorizing a link between "excess" carbs and improved neuromuscular function. The study protocol was weird and wild! Does this mean we should consume mid-podcast gels to improve joke performance? We promise to edit out the slurps. We also answered an incredible question...

We enjoyed an all-expenses-paid ambulance trip before this amazing episode! The main topic was David's harrowing bike crash. The incredible paramedics said that the impact launched him 100 feet through the air. Somehow, the concussion, a broken wrist, and lacerations seem to be the worst of it. The legs are 100%! And as all runners know, wrists and brains just get in the way. We are so happy to be alive! Life is so uncertain, and maybe the inattentive driver will be a type of spiritual...

It's the 200th episode, and we brought so much gratitude to the party! The main topic was reflecting on 5 ways our approach to endurance training/coaching has changed, based on new research and real-world experience. The topics buffet is packed with goodness: extreme-carb fueling during hard efforts, heavier strength work (in moderation), less need for high mileage (but more cross-training), increased steady running, and more double workouts/big threshold sessions. Even more important than...

We rode the inspiration wave from witnessing history for this great episode! The main topic was on the mind-boggling finish from Jasmin Paris at the Barkley Marathons. She is the first woman to finish the race, and we think it will go down as one of the most impressive endurance achievements ever. We break down why that is, and we proceed to eat some crow based on past statements about the race that she proved wrong. Jasmin dares us all to dream bigger. We also had a blast breaking down our...

We vibed with a new playlist (Taylor's version) before this great episode! The main training topic was a new study on fatigue resistance, which used a novel protocol for testing durability involving different levels of intensity. "Durability" research may be the most exciting part of modern performance science, and we broaden it out with real-world examples. We finish with our 4 big tips! You already know tip one. Yes, it involves eating. And yes, we are in the pocket of BIG CARB. We also...

We made questionable playlist decisions (arf arf) to get hyped for this amazing episode! The big topic was Lululemon's FURTHER event, a 6-day ultra in the California desert, full of intrigue and world records. Megan was on the ground as coach and science advisor, and she returns with a report that will blow your minds. What happens when a company invests millions of dollars in supporting athletes of all levels, along with ground-breaking research? And what does it mean for the future of...

We ate some business PB+Js to fuel up for this great episode! The main training topic was on fueling like your athletic life depends on it. Erase all of your preconceived notions and ask this question: When you're already tired and you're still a couple hours away from home, what do you do? If you're anything like many of the best endurance athletes in the world, you learn to stuff down as many calories as you reasonably can stomach. We break it down in a fueling tutorial, through the lens of...

We put on some see-through pants for this great episode! The main training topic was on double workouts, involving two moderate sessions in a single day. Norwegian athletes are notorious for their double threshold days, and over the last few years, we have been using an adapted approach with the treadmill or cross-training that can be implemented for trail runners, non-pros, and aging athletes. There's no "secret"... but this might be the closest thing to a training secret that we have. Don't...

We glugged some sugar with coffee and cream for this awesome episode! The main training topic was a new study breaking down the training of the 24-hour world-record holder. It gave us an excuse to talk about the trajectory of ultra training, and how we're in the midst of a fundamental shift in the sport at all levels. We also talked about a cool study on sports bra tightness and breathing patterns. The results were pretty stunning, and it may have implications for chest-strap heart rate...

We just got back from a joyful and intense weekend at the Black Canyon 100k, arguably the most competitive ultra on US soil! Endurance sports are in the midst of a fundamental shift in what's possible, from the winners to the final finishers. This year's Black Canyon was a mind-blowing demonstration of how the game is changing, with tons of lessons that apply to all goals! Topics we discussed: why the sport has taken such a big leap in the last few years, how race dynamics have changed, the...

It was the ultimate celebration episode, on a high from watching the Olympic Marathon Trials! We talked about some of our favorite storylines from the most exciting race on US soil: training partners finishing together (and our conspiracy theory), the next big star is born for female marathoners, an Olympian who walked onto her D2 college team, and so much more. Then we had some of the coolest data ever: internal stats on race day fueling from 60 case studies of successful races. Most field...

We rolled up our shorts to their full upright and locked positions for this spicy episode! A big topic was the final installment in our trilogy of updates on tensions surrounding UTMB. The letter sent by Kilian Jornet and Zach Miller to fellow pros added fuel to a fire that started at the grassroots level, finally leading to a response from UTMB. We provide some context that will be fascinating whether you're interested in trail running or just the business side of things, before coming to an...

We chugged some chocolate whole milk to fuel this amazing episode! The main training topic was on why testosterone levels are relevant for all endurance athletes. While individuals have different genetic set-points for testosterone, studies on men and women show that training and fueling interventions can change baseline levels. Those changes can be positive, leading to more energy and better performance... or negative, possibly contributing to fatigue in training and life. We break down the...

We had fire (and iron) flowing through our veins for this awesome episode! There is a big development in the UTMB controversy: reports that legends Kilian Jornet and Zach Miller sent a letter to some of the best athletes in the world considering a boycott of this year's races. We talk about what we think it means through the lens of negotiation theory. This shift in leverage could be a turning point in the UTMB drama! We also discussed emerging evidence that endurance training fundamentally...

We ate the world's largest lunches to get ready for this awesome episode! The main training discussion was on tempo running. What even is a tempo? Coaches and physiologists all disagree, leaving athletes in an uncertain spot. We cut through the noise with the help of a 2019 study looking at what training elements most strongly correlate with long-term growth. We also answered some amazing listener questions! Should men and women train at different mileage? Do NSAIDs impact adaptation? The...

We are coming in hot with some big 2024 energy! The main topic was a deeper science corner breakdown of the new study that challenges conventional wisdom on protein consumption. This research could change how you think about daily fueling, with potential benefits for adaptation and recovery. We geek out on the methodology, featuring an isotope-tagged cow, researchers screaming at participants as they weightlift to failure, and protein shakes with the consistency of sludge. And the new-year...

Welcome to a very special holiday episode! We started with our thoughts on a new study on protein intake that challenges everything we previously thought about protein metabolism. It's one of our favorite studies of all time, and it's destined to reshape the field of nutrition science! But the bulk of the episode was reading from "secrets" sent in by listeners. Some were on athletics and running; many others were about different things entirely. We think these secrets provide a beautiful...

We brought some big-time celebration vibes for this holiday episode! The main training topic was on the body of literature connecting strength work to running economy improvements. Wherever you look, there seem to be agreements mixed with contradictions, and we sprinkle some spicy controversy flakes on top of it all. Our take? Endurance athletes should probably be doing some strength work, especially with age, and we lay out a simple approach that will cost almost nothing. Two times per week,...

We loaded up on some fish candy to bring you an awesome episode! The first study of the day blew our minds, showing that just a few weeks of high-dose Omega 3 supplementation reduced some markers of heart stress after steep downhill running. We used to think that Omega 3 pills were boring, and now we have 4 jars in the pantry. Talk about some sexy science! We also talked about Taylor Swift's training plan, consisting of treadmill runs while singing her full set-list. The "Ultra Runner of...

It's one of our all-time favorite episodes after a whirlwind week! The main topic was David's race at the McDowell Mountain 50 Miler, which we use to talk about a ton of different lessons for training and racing. We're talking pre-race meals, pacing, dealing with cramps, what comes after "failure," fueling and hydration, pacing, and supershoes for trails. Plus lots of training thoughts! Outside of running, we touch on everything from how to think about race trips as vacations to the perils...

We turned the hype meters to 11 for this awesome episode! The main training topic was on the wild, uncertain science of post-exercise ketone supplementation. We take you into the cutting-edge of this emerging field of research, like a Magic Schoolbus for the scientific method. Ketone bodies are naturally produced after exercise, an evolutionary mechanism honed over millions of years. Now, through a relatively new liquid supplement, evolution has a dimmer switch. That switch could enhance...

We brought some big-time gratitude to this supersized Thanksgiving episode! The main topic was a new study looking at how fueling during training impacts next-day performance and protein degradation. We are seeing a new world order in eating and training! We also present some contrasting perspectives from prominent coaches, trying to discern between data and anecdotes, highlighting where there is nuance. The future is here. The future is TASTY. And sometimes the future will be STICKY. With...

We were extra carb-loaded for this awesome episode! The main training topic was on a new study looking at how strength work changes muscle fiber properties over time. Strength training seemed to reverse the aging clock! We dig into the nuances of what it means and how to apply the findings for endurance athletes of all ages. Invest in a big kettlebell now. The juiciest topic was the upheaval in trail running after UTMB's Whistler fiasco. It's a story as old as time, with the big power player...

Our brain juices were really flowing on this great episode! The main story came from the pro peloton in cycling, where athletes are pushing the limits of carbohydrate consumption during hard races. In general, teams closely monitor fueling to get athletes to 100-120 grams of carbs per hour (400-480 calories), and there are hints that some are pushing the limits even farther. What can we learn? Our theory: "food doping" is not just for the pros, it's the way for all of us to access our...
