    Run Elite Coach: Brutal Advice for A Sub-3 Hour Marathon After 40

    How do you run a faster marathon after 40? Whether your goal is to break 4 hours, run a sub-3:30 marathon, qualify for Boston, or eventually run a sub-3 hour marathon, Andrew Snow argues that the answer may have far less to do with adding harder workouts—and far more to do with building the foundation required to support them. Andrew Snow is a running coach and author of Run Elite, a book that takes training principles used by elite runners and translates them for recreational athletes. In this conversation, we explore how runners in their 40s, 50s and beyond can apply those principles to marathon training while dealing with limited training time, recovery capacity, work, family and the realities of getting older. We break down Andrew’s base → support → specific approach to marathon training, why he prioritizes training frequency and mileage before harder workouts, how much running you may actually need to reach your marathon potential, the role of strides and hill sprints, marathon-pace training, long runs, nutrition, recovery and race specificity. Andrew also explains why a runner trying to go from a 4-hour marathon toward sub-3 may need to think in terms of years rather than another 12- or 16-week marathon training plan—and why building a much bigger aerobic foundation could ultimately be the key to running your fastest marathon. If you’re trying to figure out how to run a faster marathon, how to break 4 hours, how to run a sub-3:30 marathon, how to run a sub-3 marathon, or how to keep improving as a masters runner, this conversation offers a very different way of thinking about long-term marathon performance. ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle 🔥 FIND YOUR TRUE ZONE 2 WITH TYMEWEARTymewear Vita Pro measures your breathing in real time to identify your individual physiological thresholds and help you train at the intensity you actually intend to train at. ➡️ Endurance Lab listeners SAVE $100 OFF the Tymewear Pro Training membership Code: E-LABTW26 👉 https://www.tymewear.com/E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM 📘 Andrew Snow’s book — Run Elite: 👉 https://www.runelitebook.com/ 🏃 Work with Andrew / Run Elite Coaching: 👉 https://www.andrewsnowcoaching.com CHAPTERS 00:00 Can you still make a huge marathon breakthrough after 40? 00:30 Why runners plateau — and how to start improving again 05:34 Should you increase mileage or change your training first? 13:08 How much mileage can a runner actually tolerate? 19:18 Autophagy, fasting and recovery for runners 25:20 The best fueling strategy for endurance performance 29:44 Nutrition fundamentals for runners 37:28 The missing ingredient: marathon-specific training 40:00 Inner Circle: The highest-ROI workout for time-crunched runners 44:50 Andrew’s Base → Support → Specific training model 57:55 How much marathon-pace training should you actually do? 1:22:49 Putting it all together: building your marathon training plan #MarathonTraining #RunningAfter40 #Marathon #MastersRunning #Running #Sub3Marathon #BostonMarathon #EnduranceTraining #RunFaster

    HRV Scientist: The NEW HRV Metric That Could Help Runners Over 40 Keep Improving

    In this episode of The Endurance Lab, I sit down with Dr. Greg Grosicki, Staff Research Scientist at WHOOP, to explore the science of HRV and HRV-CV and, more importantly, how runners can actually use these metrics to make smarter training decisions. We break down why higher HRV is generally better while lower HRV-CV is generally better, why your seven-day HRV trend can tell you something very different from today's reading, and what different combinations of HRV and HRV-CV may reveal about recovery, adaptation and accumulated training stress. We also get practical. What should you do when today's HRV is suppressed but you feel great? When should HRV actually cause you to change a planned interval workout? What happens to HRV-CV during a hard training block or taper? And can these metrics help runners recognize when they're adapting well versus drifting toward excessive fatigue? For runners over 40, we also explore an especially interesting question: how do HRV and autonomic stability change as we age? Greg discusses research showing age- and sex-related differences in HRV-CV, what may happen after around age 40, and whether exercise and fitness could help attenuate some of the age-related decline in HRV. In this episode, we cover: what HRV-CV actually measures; HRV vs HRV-CV; why HRV should be compared to your own baseline; whether wearable HRV measurements can be trusted; heat stress and HRV; daily HRV vs seven-day trends; four HRV/HRV-CV training scenarios; when to train hard versus back off; HRV-CV as a marker of adaptation; what happens during overload and tapering; HRV recovery and resilience; how HRV-CV changes with age; autonomic aging; and how Zone 2 and high-intensity training affect HRV. ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle 🔥 FIND YOUR TRUE ZONE 2 WITH TYMEWEARTymewear Vita Pro measures your breathing in real time to identify your individual physiological thresholds and help you train at the intensity you actually intend to train at. ➡️ Endurance Lab listeners SAVE $100 OFF the Tymewear Pro Training membership Code: E-LABTW26 👉 https://www.tymewear.com/E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM ➡️ Previous Endurance Lab HRV episode with Dr. Marco Altini 👉 https://youtu.be/D6ZPuaMaEgs ➡️ HRV-CV research discussed in the episode: Grosicki et al. — “Heart rate variability coefficient of variation during sleep as a digital biomarker that reflects behavior and varies by age and sex” 👉 https://pubmed.ncbi.nlm.nih.gov/41309064/ Chapters 00:00 Higher HRV vs lower HRV-CV 00:30 Using HRV to guide running training 02:21 What is HRV-CV? 08:57 The science behind HRV-CV 12:03 How new is HRV-CV? 13:48 Dr. Greg Grosicki’s journey to WHOOP 19:31 What is WHOOP? 20:43 Sleep, recovery and strain 27:42 How WHOOP uses recovery data 31:04 Inner Circle: Can you trust HRV from sports watches? 35:15 How heat stress affects HRV 37:06 Daily HRV vs 7-day HRV vs HRV-CV 39:59 Two runners with the same HRV — but very different recovery 44:09 Four HRV + HRV-CV training scenarios 47:47 The HRV-CV warning sign 49:55 How to use HRV to decide whether to train hard 53:28 When good HRV can still be misleading 54:14 Is HRV-CV a measure of adaptation? 55:16 Why low HRV-CV isn't always good 57:19 What happens to HRV-CV during hard training? 58:25 How high is too high for HRV-CV? 1:00:49 What should happen to HRV-CV during a taper? 1:01:30 HRV recovery and resilience 1:03:30 What happens to HRV-CV as we age? 1:05:44 Autonomic aging and HRV 1:08:03 How training can improve HRV and HRV-CV

    Fat Adapted Athlete: From PREDIABETES to PEAK Performance at 50

    Can you become a fat-adapted endurance athlete while still using carbohydrates to race fast? In this episode, I sit down with Sami Inkinen, endurance athlete, age-group triathlon world champion and co-founder and CEO of Virta Health, to explore how he went from discovering he had prediabetes despite being extremely lean and fit to dramatically increasing his fat oxidation and, at age 50, producing some of the best endurance performances of his life. Sami explains how changing his nutrition increased his measured maximum fat oxidation from roughly 200 to 800 calories per hour, why he describes becoming highly fat-adapted as becoming “bonk proof,” and how he combines a low-carbohydrate lifestyle with strategic carbohydrate intake during hard training and racing. We go deep into fat adaptation, metabolic health, low-carb and ketogenic diets for endurance athletes, carbohydrate periodization, fat oxidation, training after 40 and 50, prediabetes in athletes, recovery, longevity and endurance performance. Sami also breaks down his “live low, race high” approach: eating mostly real foods and minimizing carbohydrates outside training while deliberately using carbohydrates during demanding workouts and competition. Importantly, Sami repeatedly distinguishes his personal N=1 experience as an athlete from established scientific evidence and from his professional work at Virta Health. Low-carbohydrate and ketogenic approaches to endurance performance remain an actively debated area of sports nutrition research, and individual responses can vary. ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle 🔥 FIND YOUR TRUE ZONE 2 WITH TYMEWEARTymewear Vita Pro measures your breathing in real time to identify your individual physiological thresholds and help you train at the intensity you actually intend to train at. ➡️ Endurance Lab listeners SAVE $100 OFF the Tymewear Pro Training membership Code: E-LABTW26 👉 https://www.tymewear.com/E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM ➡️ Virta Health 👉 https://www.virtahealth.com/ TIMESTAMPS 00:00 Can midlife athletes have metabolic health AND peak performance? 01:22 How did an elite endurance athlete discover he was prediabetic? 09:01 Why are endurance athletes developing prediabetes? 16:29 What did Sami change after discovering he was prediabetic? 22:01 How he increased fat oxidation from ~200 to ~800 calories/hour 25:08 How low-carb does Sami actually go? 37:47 What does Sami eat day to day? 44:18 How does he use carbohydrates during hard training and racing? 52:11 Is Sami really performing better at 50 than when he was younger? 56:27 How has recovery changed with age? 58:20 Why Sami founded Virta Health 1:08:52 Sami’s training and nutrition framework for midlife endurance athletes ABOUT THIS EPISODEThis conversation is for educational and informational purposes only and is not medical or individualized nutrition advice.

    Brain Performance Scientist: How Runners Over 40 Run Faster For Longer With Brain Training

    Can training your brain help you run faster for longer after 40 — without actually getting fitter? Brain performance scientist Dr. Scott Frey joins The Endurance Lab to explain the science of Brain Endurance Training (BET) and why the brain may be one of the most overlooked determinants of endurance performance. We explore how the brain regulates perceived exertion, pacing and fatigue; how neuroplasticity could help aging athletes compensate for physiological decline; why mental fatigue can make an easy run feel hard; and what happens when cognitive training is combined with physical training. Scott also explains how he uses brain endurance training with elite and Olympic athletes, how much training is required, which cognitive tasks may work, and why mental tapering before a race could be one of the easiest performance gains available to runners. If you're a runner over 40 looking for ways to maintain performance as your physiology changes, this conversation offers a fascinating new perspective on what might be limiting you. Dr. Scott Frey is Professor Emeritus of Cognitive Neuroscience and founder of Cerebral Performance. With more than 30 years at the cutting edge of cognitive neuroscience research — and a lifetime in endurance sports — he works with athletes to apply neuroscience and psychology to performance, cognitive resilience and fatigue resistance. Scott has authored more than 100 peer-reviewed publications and books, with his research cited approximately 10,000 times. He has received more than $10 million in federal research funding and has consulted for organizations including the NIH and USA Triathlon. He is also an accomplished endurance athlete, competing in trail running, triathlon and cross-country skiing. ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle 🔥 FIND YOUR TRUE ZONE 2 WITH TYMEWEARTymewear Vita Pro measures your breathing in real time to identify your individual physiological thresholds and help you train at the intensity you actually intend to train at. ➡️ Endurance Lab listeners SAVE $100 OFF the Tymewear Pro Training membership Code: E-LABTW26 👉 https://www.tymewear.com/E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM ➡️ Scott Frey / Cerebral Performance: 👉 https://cerebralperformance.com/ Chapters: 0:00 Can Brain Training Make You Faster? 4:34 How the Brain Controls Performance 10:08 Age, Experience and Endurance 16:40 Scott’s Journey Into Brain Science 23:22 What Is Brain Endurance Training? 28:58 How Much Can Performance Improve? 41:35 Mental Tapering Before Racing 46:36 How to Start Brain Training 1:01:27 Mental Fatigue and Running 1:13:31 Exercise and the Aging Brain

    Sports Dietitian: The Nutrition Mistake Destroying Performance In Runners Over 40

    Many endurance athletes think getting leaner automatically means getting faster. But for masters runners, cyclists, and endurance athletes, there is a hidden problem that can quietly destroy performance: underfueling and low energy availability. In this episode of The Endurance Lab, I speak with Rebecca McConville, MS, RD, LD, CSSD, CEDRD, a sports dietitian specializing in endurance nutrition, Relative Energy Deficiency in Sport (RED-S), athlete fueling, and eating disorder recovery. Rebecca explains why RED-S is not just a problem affecting young female athletes, why masters athletes are often overlooked, and how trying to lose weight while increasing training volume can leave athletes stuck in a cycle of poor recovery, declining performance, and increased injury risk. Rebecca shares her own experience as a masters athlete, mother, and endurance enthusiast, explaining why so many recreational athletes fall into the trap of trying to do more training while eating less. Rebecca McConville works with athletes ranging from recreational endurance athletes to elite competitors, helping them understand the connection between nutrition, performance, health, and long-term athletic development. ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle 🔥 FIND YOUR TRUE ZONE 2 WITH TYMEWEARTymewear Vita Pro measures your breathing in real time to identify your individual physiological thresholds and help you train at the intensity you actually intend to train at. ➡️ Endurance Lab listeners SAVE $100 OFF the Tymewear Pro Training membership Code: E-LABTW26 👉 https://www.tymewear.com/E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM ➡️ Rebecca’s Website: 👉 https://beccamcconville.com ➡️ Rebecca’s book: Finding Your Sweet Spot: How to Avoid RED-S and Fuel Your Athletic Performance 👉 https://www.amazon.com/dp/1091089051?lv=shuf&channelId=500&plpRedirect=mhFallback Chapters 00:00 The hidden problem affecting masters athletes 02:30 What is low energy availability and RED-S? 04:54 Why calories are not the whole story 06:44 Are older athletes at risk of RED-S? 08:26 How athletes accidentally fall into underfueling 11:10 The long-term health consequences of chronic underfueling 13:11 Why aging can hide RED-S symptoms 14:20 Early warning signs you should not ignore 17:35 Digestion, sleep, immunity and RED-S symptoms 18:49 Can HRV and resting heart rate reveal underfueling? 20:46 Can you have low energy availability without symptoms? 21:52 Is fasted training actually beneficial? 23:28 Fat oxidation vs endurance performance 26:58 Keto diets, carbohydrates and RED-S risk 31:33 Losing body fat without destroying performance 35:03 How much energy do endurance athletes actually need? 36:27 How to recover from RED-S 39:07 Why carbohydrates matter during recovery 40:30 How long does RED-S recovery take? 44:37 Can you keep training while recovering from RED-S? 47:44 Finding help and working with RED-S specialists 50:41 The biggest nutrition mistake masters athletes make 51:35 The one nutrition change athletes should make today 52:24 What does endurance mean to Rebecca McConville?

    Endurance Scientist: The Fastest Way to Become a Fat Adapted Runner After 40

    Can you become a highly fat-adapted runner without going fully keto — and without sacrificing your ability to use carbohydrates when performance demands it? In this episode of The Endurance Lab, I sit down with exercise and nutritional physiology researcher Matt Carpenter to unpack the science of fat adaptation for endurance runners, including runners over 40. We explore what being “fat adapted” actually means, why fat adaptation is a spectrum rather than an on/off switch, and whether a ketogenic or low-carbohydrate diet is really necessary to increase fat oxidation. Matt explains how endurance training, mitochondrial capacity, carbohydrate availability and diet interact to determine how much fat you can oxidize during exercise. We also discuss how quickly fat oxidation can change, why becoming better at burning fat doesn’t automatically improve performance, and how going too far with carbohydrate restriction could reduce your metabolic flexibility and ability to perform at higher intensities. Most importantly, we get practical. Matt explains how recreational runners training around 5–7 hours per week can use carbohydrate periodization, low-carbohydrate meals and selected fasted training sessions to improve fat oxidation — while strategically using carbohydrates around hard training and racing. We also dive into Matt’s research on keto-adapted athletes and carbohydrate supplementation, including why strategically introducing carbohydrate around exercise may improve performance without necessarily undoing the adaptations developed through a low-carbohydrate diet. If you’re interested in becoming a more fat-adapted runner, ketogenic diets for endurance athletes, metabolic flexibility, fasted training, carbohydrate periodization, fat oxidation, endurance nutrition or how to fuel your running after 40, this conversation brings the science together without taking a dogmatic “high-carb vs keto” position. ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle 🔥 FIND YOUR TRUE ZONE 2 WITH TYMEWEAR Tymewear Vita Pro measures your breathing in real time to identify your individual physiological thresholds and help you train at the intensity you actually intend to train at. ➡️ Endurance Lab listeners SAVE $100 OFF the Tymewear Pro Training membership Code: E-LABTW26 👉 https://www.tymewear.com/E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM CHAPTERS 0:00 How to Become Fat Adapted 1:23 Do You Need Keto? 4:21 What Fat Adaptation Means 5:52 Mitochondria and Fat Oxidation 7:57 Fat Adaptation Is a Spectrum 10:18 Do You Need Ketosis? 15:31 Strategic Carbohydrate Use 20:17 Do Carbs Undo Fat Adaptation? 23:56 Long-Term Keto Adaptation 30:59 Fueling Long Runs on Keto 35:39 How Quickly Can You Adapt? 40:01 Diet vs Endurance Training 42:36 Fat Adaptation on 5–6 Hours 45:04 Metabolic Flexibility 49:11 Maximizing Fat AND Carbs 54:58 Train Low, Race High 57:17 Matt’s Carbohydrate Study 1:00:20 When to Use Carbohydrates 1:07:10 Keto vs High Carb: Who Wins? 1:12:29 Does Fasted Training Work? 1:16:19 Practical Fat-Adaptation Strategy 1:18:36 Why a Hybrid Approach Works 1:23:31 What Endurance Means to Matt LINKS & RESEARCH Matt Carpenter — University of Northampton: https://www.northampton.ac.uk/directories/people/matt-carpenter/ Matt Carpenter — Research Profile / Publications: https://pure.northampton.ac.uk/en/persons/matt-carpenter/ Matt Carpenter — Instagram @mattendurancescientist Carpenter, Brouner & Spendiff (2024) — Carbohydrate Supplementation Improves Ultra-Endurance Performance in a Keto-Adapted Individual: https://hrcak.srce.hr/ojs/index.php/kinesiology/article/view/27167 Volek et al.

    World Record Ultra Runner: The Proven Way to Build Extraordinary Endurance After 40

    ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle Aleksandr Sorokin went from weighing around 100 kilograms, smoking, drinking alcohol, and living an unhealthy lifestyle to becoming one of the greatest ultrarunners in the world. In this episode of The Endurance Lab, Aleksandr shares how he transformed his life, lost the weight, discovered ultrarunning, and eventually broke multiple world records in his 40s. His achievements include: 🏃 100 km world record — 6:05:35 🏃 100 mile world record — 10:51:39 🏃 6-hour world record — 98.496 km 🏃 12-hour world record — 177.410 km 🏃 24-hour world record — 319.614 km He became the first runner to break the 11-hour barrier for 100 miles, and during that same race he also set the 12-hour world record. What makes Alexander’s story even more remarkable is that he did not begin running seriously until around age 32. Before that, after finishing his earlier sporting career in kayaking, he says his lifestyle became unhealthy — alcohol, cigarettes, poor food choices, and his body weight climbed to around 100 kg. Running initially started as a way to lose weight. Then he discovered ultra-running. A few years later, he was winning major races. By his early 40s, he was breaking world records. Alexander explains how his training evolved from roughly 60–80 km per week to peak weeks around 250–300 km, why long runs of 30–50 km became the foundation of his training, how he uses interval sessions to maintain speed as he gets older, and why recovery has become increasingly important in his mid-40s. We also discuss what runners over 40 can learn from his progression, why starting later does not necessarily mean your best running years are behind you, and how consistency, training variety, mileage and simply loving the process have shaped his career. For masters runners, recreational runners, marathoners and ultrarunners, Alexander’s journey is a powerful example of how dramatically running performance can change even when you start later in life. ➡️ Save $100 on Tymewear Pro Training Membership Code: E-LABTW26 👉 https://www.tymewear.com/E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM 00:00 From 100 kg to running 1:35 Alexander’s world records 2:50 His life before running 5:43 From weight loss to world records 7:18 Did he ever expect to become elite? 10:01 Strength training and cross-training 11:03 Starting running in his 30s 12:52 Can runners still improve after 40? 16:54 How his training volume evolved 20:56 How his speed training changed with age 24:16 Mileage vs structured training 25:29 When he reached his peak 28:46 How runners over 40 can still improve 29:39 What recreational runners can learn from him 31:21 Heart rate vs pace 33:08 What to do when your best years feel behind you
