    2:25 Marathoner at 45: The PROVEN Way To Keep Getting FASTER as You AGE

    At 45 years old, Patrick Blair ran a 2:25 Boston Marathon, finishing second in his age group. Even more remarkably, he's running faster in his mid-40s than he did as a competitive college runner. His biggest training secret? Running incredibly slowly for 95–97% of his training. So how can runners over 40 continue getting faster, improve their marathon times, and avoid injuries as they age? In this episode of The Endurance Lab, Patrick Blair joins Jusman So to break down his marathon training philosophy, including why he runs most of his miles at an easy pace, how he structures his training throughout the year, and the changes that helped him break through a performance plateau. Patrick regularly runs around 100 miles per week during his higher-volume training weeks, often at surprisingly slow paces of 11–13 minutes per mile on trails. But there's much more to his success than simply running slowly. We explore the role of easy running, aerobic base training, hill sprints, strides, marathon-specific workouts, recovery, and long-term consistency in helping masters runners improve their performance. 💊 SUPPORT YOUR HEALTH WITH MICROVITAMIN MicroVitamin is designed to help fill nutritional gaps without unnecessary megadosing, with independently tested ingredients and a transparent formula. ➡️ SAVE 10% OFF with CODE: JUSMAN 👉 https://microvitamin.com/jusman 🔥 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 👉 https://www.tymewear.com/E-LABTW26 Code: E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM ➡️ Join The Endurance Lab Inner Circle on Telegram👉 https://t.me/TheEnduranceLabInnerCircle In this conversation, we discuss: - How Patrick ran a 2:25 marathon at age 45 - Why he believes running 95–97% of his training very slowly helps him perform - The difference between his approach and traditional 80/20 running - How much weekly mileage is necessary to improve marathon performance - Why hill sprints and strides helped him break through a running plateau - How to structure marathon training using base, support, and specific phases - The importance of recovery weeks and managing training intensity - Why avoiding running injuries is essential for long-term improvement - How runners in their 40s, 50s, and beyond can continue building fitness Whether you're training for your first marathon, chasing a Boston Marathon qualifying time, trying to improve your personal best, or simply wondering how to run faster after 40, this conversation offers a fascinating look at what's possible with intelligent, consistent training. Patrick's training volume is far higher than most recreational runners can realistically manage, so we also discuss how training intensity and mileage might need to differ for runners with limited time.

    Exercise Physiologist: The Brutal Truth About Zone 2 for Recreational Runners

    Why are you not getting faster with Zone 2 training? If you've been running in Zone 2 for months but your pace isn't improving, your heart rate is still high, or you're struggling to run faster at a low heart rate, this conversation with exercise physiologist Dr. Juan Murias could change how you train. Zone 2 training is often promoted as the foundation of aerobic endurance. But is running easy really enough to improve your VO₂ max, lactate threshold, and running performance—especially if you're a recreational runner training just 3–4 times per week? In this episode of The Endurance Lab, Dr. Murias breaks down research comparing five different training intensities, from moderate-intensity Zone 2 exercise to Zone 3, threshold training, VO₂ max intervals, and sprint interval training. One surprising finding: after approximately 6–7 weeks of training, the moderate-intensity group showed no statistically significant average improvement in VO₂ max or lactate thresholds compared with a group that did no training. Some individuals still improved, but higher-intensity training produced more consistent responses. So does Zone 2 training actually work? Should you spend less time running easy and more time training at higher intensities? And what is the best way to improve your Zone 2 running pace without constantly pushing your heart rate higher? We discuss: - Why your Zone 2 pace may not be improving despite consistent training - How to run faster at a lower heart rate by improving aerobic fitness - Why Zone 2 training alone may not provide enough stimulus for some runners - Zone 2 vs Zone 3 vs Zone 4 vs Zone 5 training - How VO₂ max and lactate thresholds affect running speed - Whether the 80/20 running method works for low-volume recreational runners - The role of tempo runs, threshold training, and high-intensity intervals - Why generic heart rate training zones can be misleading - How to adjust your training when you've hit a plateau - Why easy running still matters for marathon training and injury management 💊 SUPPORT YOUR HEALTH WITH MICROVITAMIN MicroVitamin is designed to help fill nutritional gaps without unnecessary megadosing, with independently tested ingredients and a transparent formula. ➡️ Endurance Lab listeners SAVE 10% OFF with CODE: JUSMAN 👉 https://microvitamin.com/jusman 🔥 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 👉 https://www.tymewear.com/E-LABTW26 Code: E-LABTW26 ➡️ Listen to my conversation with TimeWear founder Anar Larson: 👉 https://open.spotify.com/episode/5sz25EZjGUHoGSaA38nHwM ➡️ Join The Endurance Lab Inner Circle on Telegram 👉 https://t.me/TheEnduranceLabInnerCircle CHAPTERS 00:00 Why Zone 2 Isn't Working 01:48 Understanding Training Zones 08:26 Is Zone 2 Too Easy? 11:29 Zone 2 vs HIIT 21:26 The Zone 2 Study Results 23:22 Why Some Runners Don't Improve 28:49 VO₂ Max: Which Zone Wins? 31:42 How to Improve Lactate Threshold 37:48 Does 80/20 Work for Recreational Runners? 40:17 Zone 2 and Mitochondria 47:04 Why Easy Running Still Matters 49:20 Low Zone 2 vs High Zone 2 52:03 Training Only 3 Hours a Week 1:00:07 What to Do When Zone 2 Stops Working 1:07:41 Are Your Heart Rate Zones Wrong?

    Exercise Scientist: What Cannabis Really Does to Your Running Performance (THC vs CBD)

    In this episode of The Endurance Lab, I sit down with Dr. Christian Cheung, an exercise physiology researcher and senior scientist at WHOOP, to explore what the science actually says about cannabis, THC, CBD, running performance, cardiovascular health, sleep, and exercise recovery. Christian shares findings from his research examining what happens when people exercise after using THC or CBD. One particularly surprising result: participants felt they performed better after THC, even though their actual cycling time-trial performance was worse. We also discuss why THC can raise your exercising heart rate by approximately 10–20 beats per minute at the same workload, why that doesn't necessarily mean a better aerobic training stimulus, and how cannabis use may affect sleep quality, HRV, and recovery. ➡️ 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 CHAPTERS 00:00 Why runners think THC improves performance 01:56 Cannabis, THC, and CBD explained 07:03 Why people run while high 12:04 The surprising truth about THC and endurance performance 18:49 What the cycling performance study revealed 23:29 Why THC raises your heart rate during exercise 32:21 Is exercising with THC safe? 39:11 Does CBD improve performance and recovery? 42:52 Cannabis, sleep quality, HRV, and recovery 46:27 Cannabis and cardiovascular risks after 40

    3x Olympian & Elite Coach: 10 Rules to Better Running After 40 (From 5K to Marathon)

    In this episode of The Endurance Lab, I sit down with Dathan Ritzenhein, a three-time Olympian, former American record holder, World Championship medalist, and head coach of On Athletics Club (OAC), to explore the fundamentals of getting faster—and staying competitive—as we age. Dathan has experienced some of the most influential training philosophies in distance running, working with coaches including Mark Wetmore, Brad Hudson, Alberto Salazar, and the Hansons. Today, he draws on those experiences to coach some of the world's best runners.But what happens when we apply those elite training principles to marathon runners in their 40s, 50s, and 60s? We explore why consistency matters more than chasing mileage, how to balance training volume and intensity, why masters runners shouldn't abandon speed work, and whether popular approaches like Norwegian double-threshold training make sense for recreational marathoners. Dathan also explains how he would structure marathon training for a 50-year-old runner with limited training time who's trying to qualify for Boston, including how to organize workouts, long runs, strength training, and recovery. ➡️ 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 ➡️ On Athletics Club (OAC) 👉 https://www.on.com/en-fi/explore/athletes/oac-global?

    She Finally Broke 3 Hours at Age 49 - Her Advice for Your Fastest Marathon After 40

    At age 49, Marilyn Tarkalson ran a 2:58 marathon, breaking 3 hours after previously running 3:21 and 3:14. Now, at age 50, she’s still trying to get faster. In this conversation, we break down exactly what changed in Marilyn’s marathon training, nutrition, recovery and mindset. Whether you’re trying to run a sub-4 marathon, sub-3:30 marathon, qualify for Boston, break 3 hours, or simply run a faster marathon after 40, Marilyn’s progression offers a fascinating look at what it can take to keep improving as a masters runner. Marilyn explains how she structures her training using a base → support → specific approach, how she built toward 50–60 mile weeks, why strides and speed work remain important as we age, and how she incorporates threshold training, marathon-pace workouts and long runs. We also discuss how she balances harder training with injury prevention and recovery. But training was only part of her breakthrough. Marilyn says nutrition was the starting point. She explains how moving toward a whole-food plant-based diet affected how she felt and recovered, what she eats as an endurance athlete, and how she thinks about nutrients such as iron, ferritin, B12 and vitamin D. We also get into strength training for runners over 40, recovery, sleep, HRV, menopause and HRT, and the mindset shift that took Marilyn from believing a sub-3 marathon was impossible to running 2:58 at age 49. Perhaps most importantly, Marilyn doesn’t believe her best running necessarily has to be behind her. At 50, she’s still developing as an athlete and is now chasing an even faster marathon. If you’re a masters runner, midlife runner, marathon runner over 40 or over 50, or you’re simply wondering how to improve your marathon time as you get older, this conversation is a reminder that meaningful improvement can still be possible with consistent training, recovery, nutrition and patience. ➡️ 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 🏃 Work with Andrew / Run Elite Coaching: 👉 https://www.andrewsnowcoaching.com CHAPTERS 00:00 From 3:21 to a 2:58 marathon at age 49 00:51 Marilyn’s running journey — and years of getting injured 06:12 How she went from 3:21 to breaking 3 hours 07:00 Training vs nutrition vs mindset: what changed the most? 10:32 What Marilyn eats as a plant-based marathon runner 14:05 How changing her diet affected recovery and performance 22:46 How she trained to run a sub-3 marathon 29:32 Marathon-specific training and marathon-pace workouts 34:18 Why speed still matters for runners over 40 41:54 Balancing speed work, recovery and injury prevention 46:41 Strength training for runners as they get older 54:26 Recovery, HRV, sleep and training fatigue 1:01:43 Why she’s chasing a 2:54 marathon at age 50

    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.
