Empirical Cycling Podcast

Kolie sits down with Cory Lockwood to discuss breaking the U.S. 40km ITT record, going under 45 minutes. Cory also talks about what's different working with Kolie from previous training he's done, along with observations about rest, FTP and VO2max training, training during race season, and reflections on what it means to be both an athlete and coach.

This episode answers the question: is there something unique about endurance riding that is unavailable at other intensities? After discussing "zone 2" definitions, we look at adaptations and dose relative to other training intensities, fatigue, and volume. We look at the relative necessity of endurance riding in both very low and high volume training, and answer listener questions, including if t...

Master coach and WKO5 product leader Tim Cusick joins the podcast to get his brain thoroughly picked. Training topics include the biggest differences between average cyclists and the top pros, the usual periodization schemes vs Olympic cycles, the evolutionary process of a training plan, expertise vs mastery, and of course, resting. Data topics include whether we'll ever get the AI coach in our li...

To celebrate 400,000 podcast listens, we answer your questions submitted in the Empirical Cycling Instagram stories. We discuss high and low volume training and progressive overload, 3 things every cyclist should do, low CHO training, FRC for mountain bikers, supplements for athletes, our best non-empirical cycling advice, and much more. The full questions list is available on the website.

This episode breaks down the origins of endurance performance and how cells control substrate oxidation. We review a paper looking at the difference in adaptive aerobic signals when participants used significantly different amounts of fat and carbs at the same intensity. We then look at the role of mitochondria in cellular energetics, the pivotal role they play in aerobic endurance adaptations, an...

Are you a CTL junkie? Terrified of letting it drop? Listen in. This episode takes a critical but realistic look at TSS and the metrics it's built on like CTL, ATL, and TSB. We discuss normalized power, what kind of fitness CTL can actually reflect, and answer listener questions.

Andy Coggan joins the podcast again to discuss everything we didn't get to in the previous episode. We get back stories behind the adaptations by training zones chart and the category and w/kg chart. We also go in depth with nitrate supplementation, vo2max training. if burning fat makes you burn more fat, if signaling studies translate to performance, and the nature of adaptation itself. There are...

In this episode, Andy Coggan discusses FTP and its context among various threshold definitions, the infamous "hour of power", and the legacy of Training And Racing With A Power Meter. We also discuss Andy's lack of social media presence, the chapters he's written on the history of exercise physiology, and delve into some topics in exercise metabolism including VLamax, substrate use at FTP, methods...

The interviewer becomes the interviewed as the host of That Triathlon Show joins Kolie. Mikael talks about what he takes from all the interviews he does and how they change his approach, multisport training and periodization, podcasting, pacing, and what Mikael's favorite meme is. He also answers your listener questions.

More FTP may be better, but not always. This episode explores ideas around how FTP can be overemphasized in training in both the short and long term, leading to suboptimal fitness and race outcomes.

Think your FTP is the power you can hold for 60 minutes? Think again! We dig into a classic Billat paper on time to exhaustion (TTE) and training threshold by adding time in zone. Then we discuss into the metabolic implications of these results, how they align with real world experience, and how this affects training and assessment of its effectiveness. Finally, we answer your questions as asked i...

Should you always train like you race? In this episode we investigate three myths related to this idea, and find some grains of truth along the way. The myths are 1. Sprinters and non-sprinters really need to train aerobic systems differently. 2. Crit racers mostly need to focus on anaerobic efforts. 3. You won’t need to train FTP if you don't race time trials. We touch on some track sprinting as...

Marinus Petersen of Kilowatt Coaching and graduate of Loughborough University joins us in this episode to discuss a recent paper on bias in research, but it of course evolves into much more. We discuss the line between scientific research and real world experience and the usual suspects in a conversation between coaches including lactate, critical power, warmups, and more.

This episode explores how individualization of training is why the answer to almost every question is "It Depends." We discuss a few things like tapering, volume, intensity, recovery, the one instance we could think of where there is a definite answer, and also take listener questions submitted from Kolie's Instagram.

RJ Boergers and Angelo Gingerelli join for a discussion of strength training for endurance cyclists, their book "Finish Strong" as well. The episode is full of practical takeaways and in depth discussion of strength training principles.

We begin our foray into listener-submitted training myths, looking at the largest issues with the claims, and discussing why, as always, it depends. This episode's myths are: 1. Low cadence riding is strength training. 2. Burning more fat makes you better at burning fat. 3. You should do your base rides in the little ring. Please reach out if you'd like to submit a training myth!

While the phosphocreatine energy system is well known for sprinting, it also has another crucial role as part of the aerobic energy system. We delve into creatine's part in not only temporal energy buffering, but spatial too, and how cells are organized to support this and how badly organisms suffer without it. Then we look at more research showing that the aerobic recovery of phosphocreatine is h...

Multidiscipline coach and former MMA fighter Matt DesRoches of Resilience Health & Performance Consulting joins Kolie for a wide ranging conversation on training, measurement and metrics, cutting weight, the physiology of cycling vs team sports, recovery and adaptation, pacing, interpreting scientific papers, noob gains, and much more.

Can we really replace volume with intensity? We discuss the dos and don'ts of training on low volume, time crunched training, the principles that should guide you, and some tips to make sure the training time is being maximized. We touch on whether you should plan via TSS, how many hard days per week, polarized vs pyramidal and sweetspot, why and how RPE is incredibly useful, and more. Plus we ans...

Coach Katie goes in depth with her overtraining history in both cycling and swimming. We discuss the various causes like intensity, nutrition, and sleep, and the associated symptoms, along with her recovery each time, and how this experience helps in her coaching. The episode concludes with some tips to help recognize and avoid overtraining, along with listener questions.

This discussion with Namrita centers on ride food questions like how much, when, how to adjust for early rides, races, and if protein and fat is necessary. Additional side quests include the glucose-fructose ratio, how important ride food is in the context of the day, gastric emptying rate, the effects of caffeine, solid vs liquid food, and many others.

Kolie and Kyle discuss the mental and physical aspects of going into an FTP test and add some perspective on nerves, rest, and softening blows to the ego. Then three alternative RPE or data based, submaximal methods are discussed. We also touch on tests that go too well and how to adjust to realistic numbers for training, and why it's better to be consistent than play whack-a-mole with occasional...

CTS coach Adam Pulford shares his thoughts on the ins and outs of recovery and how crucial it is. Topics including signs you need a rest week, how often you should take one, rest week structure, if sprints are okay during a recovery day, and the benefits of apple picking.

In this ground-breaking, tell-all episode, Kolie needles Kyle before he pulls at a thread, and Kyle's yarn untangles the skein of reality and explains how you can use the underlying fabric of the universe to bring your cycling performance to the next level.

Former national time trial champion Cory Lockwood fields questions from Kolie and podcast listeners about the ins and outs of time trialing, including his #1 tip for time trialists of all levels. We cover pacing, gearing and equipment selection, and mental focus. Plus we talk about how Cory's training is going, fueling for big workout days, the team behind a big performance, and the unexpected use...
