Episode 11: Tommy Rivers Puzey, Motivations, Aspirations, Training, Durability, Injury Prevention, Run Commuting, Diet, and more



In episode 11 of the Art and Science of Running Podcast we visit with Tommy Rivers Puzey. Tommy is a husband, father, accomplished marathoner, trail and ultra runner, iFit Trainer, anthropologist, linguist, doctor of physical therapy and licensed massage therapist who works on some of the best endurance athletes in the world when they are training in his hometown of Flagstaff, Arizona.

What motivates Tommy to get out the door and run?

“Trying to keep my own mental and physical health in check. Movement outside helps me keep my own emotional health.”

“The first biggest motivator is to get my head on straight before the rest of the day starts.”

“There are few people whose company I enjoy as much as the voices in my own head.”

“More than anything, I’m motivated by fear of not reaching my potential.”

What was it like growing up in the Puzey home?

“We always knew that we were loved, but there was always an expectation to excel.”

What motivated Tommy to pursue the academic tracks that he pursued?

“Our dad taught us from a young age that you can either work with your hands or you can work with your mind. If you choose to work with your mind, you have to go to college and if you want to go to college I’m not going to pay for it so you either have to be a scholar or an athlete or both.”

“We knew that if we wanted to work with our minds that we needed to go to college so we tried to become the best students and athletes that we could be so that we could pay for college.”

“Waste of any kind is sinful. Waste of food, waste of time, waste of opportunity. Waste of potential is the very worst form of waste.”

“Anthropology class felt like Sunday dinner with our family. It just felt like home being in the anthropology department and that’s what Jake was studying so that’s what I did.”

When did athletics come into the picture?

“Our recreation as kids was simply being outside in the rural southwest.”

“You learn to run as kids and then you are told to stop and then eventually listen. Whether it’s for church, or school, or the pool. We learned to run as kids and we just never stopped.”

Tommy has had success on the trails and the roads. Some find the transition back and forth difficult.

How does he specifically target specific types of running races?

“I start my weeks from the back to the front. . . People have these preconceived notions that you are either a trail runner or a road runner. One of the first things I learned about when I first started studying human physiology is Wolff’s Law. Wolff’s Law essentially says that bones will strengthen themselves. The fibres of the bones will align themselves specifically in response to the stresses that are placed upon them. If you stress a tissue or blood or tendon a little bit those tissues will make adaptations and become what they are being trained to become. If you stress it too much without adequate recovery you will get injured.”

Tommy’ weekly training schedule:

  • Five days a week Tommy does what he calls the Vuelta del Taco Run which is 10 miles from his home on a dirt mountain road to Del Taco where he eats a burrito and drinks a Powerade and then he returns home (10 miles) on the same mountain run. These 20 mile runs are done below the first ventilatory threshold at a heart rate of about 140 BPM. The last mile or two of the runs, Tommy inserts 4-6 x 30 second strides.

“Other than that, I do strides. I define strides as pretending that I’m starting a 10K race 4-6 times in the last mile of my run.”

  • Hard, race specific work with a group – either on the road or the track.

“I feel like I need to do really hard, specific work on the track or the road to keep the turnover going up and working the neurology.”

  • Day in the Canyon – 5,000 ft down and 5,000 ft up – usually to the River or Phantom Ranch and back up.

“If I maintain the durability that comes from running in the [Grand] Canyon once a week, I can handle better the impact that comes on my legs if I’m racing hard on any kind of course.”

“I try to find a way to make training a part of my everyday life. Figure out ways to make training not be something that you dread and something that you enjoy.”

“If I do it that way, there is always going to be stress, but emotional stress isn’t going to be one of the stresses. If there is not emotional stress contributing to that total pool of stress from my training – if it’s not something that I dread. If I’m not worried about hitting a certain pace or heart rate zone then my total overall level of stress is lower which means my cortisol levels are lower and my testosterone is higher and then my mood is better and my energy is greater. All of the things that people are illegally doing to try gain an advantage. You can get all of those same advantages by changing your perspective and mindset of what you’re doing.

“I learned that from run commuting during graduate school. I was running 24 miles a day to and from school. It never felt like I was training because it was simply my mode of transportation to and from school.”

“If you cannot injure yourself during a marathon, you’re the fittest you’ve ever been three weeks after the marathon. Your body can absorb the fitness, the durability, the neuromuscular efficiency from that marathon the same way that it can from any training run.”

Tommy recommends the book, 80/20 Running by Matt Fitzgerald as a foundation upon which training should be designed: “80% percent of training should be under your first ventilatory threshold. What’s important is that the other 20% needs to be at a high intensity. If you’re running 100 miles a week that means that you can do 20 miles of quality work. The problem is that people don’t do 100 miles a week and want everyday to be a high intensity interval workout.”

“Too many people don’t run the slow runs slow enough that they aren’t able to do their hard runs hard enough. Without adequate stress and rest runners aren’t able to absorb the training that they are doing and then they can’t make the gains they are hoping to make.”

Durability and Recovery

“The easiest way to recover from a race is to be in shape for the race before you run the race.”

“There’s not a quick way to do it. You have to earn the fitness, the durability. And slowly, slowly build up.”

“It has nothing to do with effort. Emotionally you may be tough enough, but structurally you have to be tough enough otherwise you will break.”

Food, Diet, Nutrition, Weight and Supplementation

Tommy recognizes that everyone is different and our bodies are able to adapt to a lot of different fuel sources, but the best way he finds to describe his own diet is with the words of Michael Pollan from his book, In Defense of Food:

“Eat food, mostly plants. Not too much.”

“The more food I eat, the better I feel and the more energy I will have, but if I eat food and don’t burn it I will wear it. . . . If I don’t run over 100 miles a week I’m 180 lbs. If I don’t run enough miles, my body isn’t a runner’s body. It’s a farm kid’s body.”

“I find that learning to identify cravings has been really, really helpful. If I’m craving something sweet it’s that my body is craving carbohydrates. So I could eat a bag of Swedish Fish or I could eat bananas. And if I eat bananas, I will feel better. If I’m craving fat, I could go eat ribs, or I could add an avocado to my meal and if I eat the avocado I’ll feel better after. If I’m craving salt, I could eat a whole bag of potato chips or I could eat a pickle. Learning to listen to my body and what it’s telling me based on my cravings has been really helpful. Having an entire spectrum of options of things that will help me towards my goals and which things will hinder me is also helpful.”

“Another thing that helps me is to eliminate refined foods except during really intense training and racing.”

“I can get away with a lot of things that others can’t get away with because of how much I train.”

“The less meat I eat, the better I feel. But if I eat no meat then I have a really hard time regulating my energy. I would love to. I feel like the world would be better if we ate more plants and less meat. I’m more motivated to not consume any animal products because I don’t like the idea of killing animals more than any health benefits.”

“I kinda go back and forth depending on the time of year, what I eat. Depending on my cravings, depending on my training load.”

“I know a lot of people that are really, really strict with their diet and they run really fast and I know a bunch of dudes here [Flagstaff] who seemingly fuel off of beer and pizza and they’re the fastest people in the world.”

“Our bodies are incredibly, incredibly adaptable and they can take almost any combination of foods as long as everything that is needed is present and do incredible things with that. I think that just a reflection of how adaptable our bodies are and how unique our microbiomes are.”

Supplementation

Tommy shares the supplements that he takes:

Daily routine:

Wake up, get caffeinated and hydrated (sip some sort of hot caffeinated drink for a couple of hours while I read). Might drink simple electrolyte drink. “Recovery will be quicker if I don’t get dehydrated.” Eat bananas + walnuts. Run. Recovery shake with Ultragen, bananas, berries, peanut butter, etc. Half gallon.

“I eat almost completely plant based carbs for the first 8 hours of the day and then when I’m trying to “harden up” and get lean before a race, I eat almost exclusively animal protein after 4 pm until the next morning. So all carbs for the first 8 hours of the day and then no carbs for the next 16 hours.”

“There’s nothing magical about walnuts. I just like them.”

“I eat a lot of walnuts and a lot of bananas. 10 bananas a day and lots of rice and beans.”

Weight, Weight Loss, and Disordered Eating

“It’s typically easier to lose weight than to gain fitness.

“This is not as simple as the equation that fitness = amount of energy that you can put out / kg”

“The female endocrine system is very different than a male endocrine system.”

“I try not to let my mind to get too consumed by it. It’s not popular for males to talk about body dysmorphia and disordered eating, but it’s real. It’s definitely something that I’ve wrestled with for two decades. Sometimes its easier than other times.”

“I think because we grew up around wrestlers we didn’t ever view it as disordered eating. It’s not so much based off of trying to look the way that I think a normal male would want to look. It’s trying to look like the East Africans that I line up next to. It’s not healthy. It doesn’t look good. It’s not sustainable.”

“There’s a huge amount of pressure to run as fast as you can within the rules. It is a form of abuse if it is pushed upon you from another individual. But for me it has always been about fear of not reaching my potential. What could you do if you trimmed a couple more pounds off?”

“The hard part is that it’s physics. But what you’re not told in that simple one-dimensional physics equation are the other five dimensions that come into play: longevity, mental health, durability, bone density, confidence are the other things that you can struggle with for the rest of your life. For males it’s different than it is for females, but none of it is sustainable or something you would wish upon another person.”

“Take the stress out of it in any way that you can and do it because you love it.”

“I’ve been super fit and depressed and run terribly and I’ve been a little bit soft and stoked to be in it and run completely out of my mind. I’d rather be soft and happy than hard and sad.”

Episode 10: Manu Vilaseca, Trail & Ultrarunning, UTMB, Stage Racing, Coaching, Travelling, Language Learning, and more



In this episode of the Art and Science of Running podcast we speak with international trail and ultrarunning superstar, Manu Vilaseca.

In this conversation, long-time coach, Jacob Puzey, chats with Manu about her experiences at UTMB, moving to a new country and learning a new language, cross training, training for a stage race, and how coaching has helped her become a better runner.

They also discuss how Manu’s background as a multi-sport athlete training in Brazil has informed the way that she trains and coaches those she coaches in Catalunya and beyond. They specifically discuss the old school HIIT workouts, Cruz Intervals, named affectionately after Brazilian mid-distance star, Joaquim Cruz that Manu and Jacob suggest for some of their athletes to work on speed, agility, and power – especially when they aren’t able to train on trails.

Manu hails from Rio de Jainero, Brazil, and currently resides in Moiá, Catalunya where she and her partner, Gerard Morales, lead a group of athletes known as Team Peak Run Moiá.

Manu has a background in product design and a gift for learning languages. She loves travelling to races around the world and learning about the people and the places she explores on foot. To date, Manu speaks Catalan, English, French, Portuguese, and Spanish.

Manu has placed top ten at two of the uber competitive UTMB races, UTMB and TDS and has been ranked top ten in the Ultra Trail World Tour for her top performances at internationally competitive ultramarathons around the world. In 2019, Manu placed 5th at TDS in what she describes as one of the most challenging courses she has encountered thus far.

In addition to training together, Manu and Gerard will be teaming up to to tackle the Everest Trail Race in Nepal.  Manu ran it last year and will be returning with her partner to see how they fair against the altitude and the elements.

Episode 9: World Marathon Records are Falling, Ineos 1:59, Breaking 2, Nike Vaporfly 4%, Mechanical Doping, and more



In this episode of the Art and Science of Running Podcast, we discuss the history of the Breaking 2 project, the Ineos 1:59 Challenge, collaborative coaching, the evolution of footwear, fuelling, pacer formations, world marathon records, doping, mechanical doping, and more.

The History of Breaking 2

It all started at the 2013 Great North Run (Half Marathon) between the all-time greats, Haile Gebrselassie, Kenenisa Bekele, and Mo Farah.

Yanis Pitsiladis, the foremost expert in genetics in East Africa based at the University of Brighton formulated the sub 2:00 concept. Pitsiladis approached the 2 hour barrier through a collaborative effort at various universities, but his project ultimately stalled and stopped growing.

In 2016 Nike launched its own project. After his marathon debut in 2014, Kenenisa Bekele was headhunted to be one of the athletes to prepare to break 2 hours. Ultimately, it was not Bekele, but rather Kipchoge of Kenya and two others, Zersenay Tadese of Eritrea, and Lelisa Desisa of Ethiopia.

Breaking 2 was truly scientifically motivated. Ultimately Kipchoge ran 2:00:25.

Alex Hutchinson was there and wrote about the experiment in Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance.

After coming within 25 seconds of the 2 hour barrier in Breaking 2, Kipchoge broke the world record in Berlin in 2018 in 2:01:39. After running and winning the London Marathon in 2019 the best option to try to break 2 hours in a controlled setting would be the Fall of 2019 before focussing on the 2020 Olympics.

In episode 4 with Alex Leuchanka, the Senior Applied Innovation Officer for VF Corp we discussed some of the work he and others are doing in the field of data collection in biomechanics. Alex mentioned a key note address at a conference he had attended in the area detailing the extensive data collection Nike had been doing to inform shoe design.

Nike was able to predict with hyper accuracy what Kipchoge was going to run at Berlin based on the models they were able to create from the data collected win training. Leading up to the Ineos 1:59 there was so much data collected over the years that there was little doubt that Kipchoge would not break 2:00.

“If you can take anything out of this, it is that Kipchoge is an absolute role model for any runner in mindset and mind control. . . [He is] amazing at being able to turn up on the day and execute. His ability to get into this flow state / mindset / brain state is insanely good. His ability to stay concentrated and relaxed for two hours, but he could also take direction while on the run. He naturally has this ability to drop in and out of flow state for two hours straight which makes him hyper efficient.”

Malc Kent

Coach / Athlete Relationship

The coach / athlete relationship between Kipchoge and Patrick Sang is more collaborative and athlete guided than some might suspect.

The goal of a coach is to help our athletes not need us. Ultimately, the goal of both coach and athlete is to trust the process with the goal of long term-development.

As we discussed in Episode 2 of the Art and Science of Running Podcast, Eliud is the patriarch of the group.

“What is amazing is how incredibly anchored and stable he is. He could have looked things up on the Internet and second guessed what he was doing, but he didn’t. He accepted the process, the simplicity.”

Malc Kent

Introducing the Nike Vaporfly 4%

The Nike Vaporflies were worn in competition for the first time at 2016 US Olympic Marathon Trials.

With some metabolic data studies it was determined that the original Vaporflys gave an average of 4% increase in running economy and as much as 6%.

As discussed in Episode 4 of the Art and Science of Running Podcast, the distinguishing feature of these shoes is the Pebax foam with carbon fibre plate.

Latest available model in this line is called the Nike Zoom Vaporfly Next %.

Kipchoge wore the “Alphaflys” in the Ineos 1:59 Challenge. These shoes are believed to also include pebax foam, forefoot pods, and multiple carbon fiber plates.

Although these shoes were not shared with the general public until just before the Ineos 1:59 Challenge, Nike filed a patent application in US in November 2018 for the concept of the shoe worn at the Ineos 1:59 Challenge.

So without taking away from all that Kipchoge and others have accomplished in these new Nike technologies, it begs the question:

Is it the shoes?

Would Kipchoge have been able to break 2 without the shoes?

Would Bekele have been able to do what he did by almost besting Kipchoge’s mark in the marathon without the shoes?

Would others have been able to do what they have done without the shoes? (See lists of top marathon times of all time).

Rodger Cram’s study of the original Nike Vaporfly prototype showed an improvement of 4%.

And it is rumoured that the Next % gives even more back.

For comparison of the Nike Vaporfly models and how / why their return varies from model to model:

Stack heights – height of mid sole.

  • Vaporfly 4% return, 31 mm
  • Next % – 5% return, 36 mm
  • Alphafly – 6% – possibly more, 41 mm

But this isn’t just about metabolic tests in a lab. Times are dropping at an unprecedented rate.

See list of all time fastest marathon times and courses: https://www.runnersworld.com/races-places/a20823734/these-are-the-worlds-fastest-marathoners-and-marathon-courses/

Eight out of ten of the ten times of all time have been run since 2016 and the advent of the Nike Vaporflys.*

“It is not unreasonable to suggest that the shoe that we are looking with pebax foam has about twice the energy return of comparable foams.”

Malc Kent

There is no question that the shoes helped Kipchoge run sub 2:00 in Vienna.

What could Kipchoge do if he wore the Nike Zoom Streak 6?

Malc mentions a trend that the heavier the runner the more return they get from these new Nike Vaporflies.

According to the data Malc has recorded and analyzed, trends in the data indicate that the heavier the runner the greater the advantage that they get.

Supply and Demand

Pebax is a naturally occurring crop. The demand is greater than the supply. Nike has already monopolized the available Pebax in the world (China).

A number of formerly sponsored athletes by non-Nike brands elected to wear Nike Next % at the Canadian Marathon Trails and saw big improvements at the Toronto Waterfront Marathon.

Read more at Inside the Race that Changed Canadian Marathoning.

Rather than wearing the Vaporflies, Jacob is currently working with Alex to try to develop the best shoe that they can before CIM.

Doping vs. Mechanical Doping

Those who use EPO as a performance enhancer hope to get 4-5% of an improvement gain. Recent improvements over the marathon distance indicate that those who use the Vaporflies are getting at least as much of a boost from the shoes as they would if they were using synthetic EPO.

Relative to history, how do recent performances in the Vaporflies stack up?

See list of all time fastest marathon times and courses: https://www.runnersworld.com/races-places/a20823734/these-are-the-worlds-fastest-marathoners-and-marathon-courses/

Let’s Run Founders suggest that the results of the 2016 Olympic Marathon should be overturned. This would include the results of the 2016 US Marathon Trails because those who qualified and medaled were wearing Vaporflies which were not available to the general public which technically is against IAAF rules. https://podcasts.apple.com/ca/podcast/letsrun-coms-track-talk/id383631335?i=1000453816857

One argument against banning the Nike Vaporflies that Alex Hutchinson makes in the Clean Sport Collective and House of Run podcasts is that Adidas and Fila each had shoes with carbon fiber plates including the shoes that Haile Gebrselassie wore to set a new marathon world record. Clean Sport Collective Podcast & House of Run Podcast.

Some of these shoes were conceptualized in Calgary at the University of Calgary. For more information on the extensive biomechanical work done in this department, listen to this podcast with head of department at the University of Calgary, Benno Nigg, with Malc Kent: https://runfisix.com/blogs/podcasts/benno-nigg

Geoffrey Burns argues that we can and should embrace innovation and technology, but there should be limits in order to preserve the integrity and ethos of the sport. Burns suggests a restriction of stack height to regulate artificial advantage.

https://blogs.bmj.com/bjsm/2019/10/14/shoes-and-sub-2-hr-marathon/ 

Burns also suggests that in order to maintain the tradition of fair play in the sport and the ability to compare records from generation to generation there should be some restrictions to technological advancements:

https://www.geoffreyburns.com/stream/trading-souls-for-soles

Malc thinks that perhaps a lower profile shoe like the one worn by Gebrselassie or the Nike Zoom Streak would be truer to the ethos of fair sport, whereas Burns is allowing the original Vaporflies to be counted.

Doping is not just about performance on race day, but recovery in training so that greater gains can be made before race day.

“If the shoes are allowing you to do two more reps per session or add a few more quality training sessions without as great a need for recovery between long runs and workouts that is giving the athlete an advantage comparable to the advantages given by using EPO or other banned substances.”

Jacob Puzey

In the year 2000 only one American male had run the Olympic qualifier, yet in 2019 at the Chicago Marathon 10 American men ran under 2:12 – all wearing either the Nike Vaporflies or Hoka and Saucony equivalents (or attempts to compete with the Vapoflies, etc.)

Read more on the results and the impact of the shoes: https://www.runnersworld.com/news/a29452570/chicago-marathon-american-men-results-2019/

Malc challenges listeners to watch the last five minutes of the Ineos 1:59 and decide how powerful the shoes are. Propulsion is one thing and reduction of fatigue is another thing. That’s the power of shoe technology right there.

Episode 8: Sanjay Sachdev talks World Champs, Training through Cancer, Positivity, Perspective, Perseverance and more



Imagine being in the best shape of your life and qualifying to represent your county at the next world championships. And then imagine discovering a malignant mass while still recovering from the national championships.

In this episode of the Art and Science of Running Podcast we speak with Sanjay Sachdev shortly after he competed at the 50K Road World Championships in Romania and just over a year after being diagnosed with testicular cancer. He shares what he learned through the process, how he stayed positive through treatment, and how the past year of cancer treatment led to a new appreciation for life, family, running and led to a new perspective on training that resulted in lifetime best for 50K at the world championships!

Just weeks after qualifying for the World 50K Road Championships in May 2018, Sanjay found a mass on his testicle. Over the next few weeks, he had the mass surgically removed, was diagnosed with embryonal carcinoma testicular cancer, and then started the process of trying to find and eliminate the cancer.

Throughout this time, Sanjay exercised 83/84 days while undergoing treatment for cancer both to maintain health and to provide purpose to each day.

Prior to cancer, running was always a means of dealing with stress from work and life so Sanjay pushed most runs.

“This past year has forced me to slow down. I look at the overall benefit and the overall time difference and the numerical values and I have to ask myself, ‘Holy smokes, what was I doing before?”

Sanjay has a demanding, stressful, dangerous job. He could choose to see life or the world through a very negative lens, but instead he is one of the most positive, optimistic people that Malc and Jacob have ever encountered.

“To stay positive, I think you have to be around positive people.”

“Are you going to let adversity define you or are you going to define yourself through the adversity?”

“You’re a lot of things before you’re a cancer patient. Stay true to the things you are before, and you’re going to come out on top. For me, I looked in the mirror and went through the list and made sure I did something each day as a husband, father, athlete  . . . and then you get to the part where it’s like, ok, you have cancer. Make sure you do what you have to do to get through this.”

Sanjay’s optimism extends beyond day to day life to his running. Rather than freaking out when things don’t go as planned, Sanjay adapts on the fly and makes the most of each situation. This has led him to have positive results, even when conditions or circumstances are less than ideal.

Episode 7: Speed vs. Stamina, Race Specificity, Bowerman Track Club, Exhibition 5K, and more.



In this episode we discuss the pros and cons, risks and rewards of speed and stamina work.

We discuss how the Bowerman Track Club athletes train together for different events from the mile to the marathon, but do much of their stamina training together. We specifically discuss a recent 5K time trial they did as a team at the Nike World Headquarters in Beaverton, Oregon, USA, in which three team members (Woody Kincaid, Lopez Lamong, and Matt Centrowitz paced by Moh Ahmed) ran under 13:00 for 5K.

Woody Kincaid breaks down the exhibition 5K on the Citius Mag Podcast.

Jacob shares more insight on the topic of speed vs. stamina training in SPEED vs. STAMINA

Jacob also suggests additional reading of You: Only Faster by Greg McMillan to learn how to best tailor training to yourself and Running to the Edge by Matthew Futterman to learn more about training at the threshold.

Episode 4: Using wearable technology to inform running shoe design



We met with Alex Leuchanka, the Senior Applied Innovation Officer for VF Corp (Altra, The North Face, Timberland, Vans, etc.) to discuss the role of wearable technologies in the development of footwear.

Malc, Jacob, and Alex met at Versa MC in Calgary to discuss biomechanics and footwear development

Alex was in the area attending and presenting at two biomechanics conferences – one specifically for footwear and the other for biomechanics in general.

His presentations can be found through the links below:

Use of Wearable Sensors for Measurement of Spatiotemporal Variables During Marathon Race Poster

Use of Wearable Sensors for Measurement of Spatiotemporal Variables During Marathon Race Abstract

Exploring Kinematic Asymmetry by Means of Wearable Sensors During Marathon Race Poster

Exploring KinematicAsymmetry by Means of a Wearable Sensors During Marathon Race Abstract

Alex describes the work he does using wearable technologies to determine how the body responds to certain types of footwear, terrain, etc. Whereas in the past one had to do all of the testing in a lab, with advancements in technology he can now measure 4D movement of an individual with incredible accuracy to determine how to improve footwear development.

Jacob plans to use RunScribe sensors in training and Alex and Malc will review the data to determine which shoe models work best for him and what injury prevention protocols to follow.

Malc uses wearable technology to help runners from all over the avoid injury.

Alex uses wearable technology specifically to inform footwear development and will be working with Jacob and other VF athletes (The North Face and Altra) to gather training and racing data to hopefully create better shoes to meet their training and racing demands.

Wearable technology has been overly simplistic in the past, but RunScribe now has the ability to look at up to 35 – 40 parameters.

Recently, Alex has been comparing the Nike Vaporfly 4% Flyknit shoe and the Altra Escalante Racer.  His posters and presentations (above) show some of his findings.

Alex suggests that the gains made by the 4% are not simply due to the carbon plate, but primarily due to the newer Pbax foam compound.

As an undergraduate and graduate student and the University of New Hampshire, Alex studied zero drop technology and how the body responds to it.  In fact, his department developed a transition protocol from traditional shoes to zero drop over the course of several weeks.

Alex describes the process of shoe development and modification.

A team of developers puts the shoe together, creates prototypes, test prototypes, and gets feedback from wear testers, but to make even minor modifications comes at a great cost and generally takes time.

All of this and more in Episode 4 of the Art and Science of Running Podcast.

Episode 2: Group Training, NN Running, Recovery, Trusting the Process



Live from Malc’s basement in Cochrane, Alberta, co-hosts Malc Kent and Jacob Puzey discuss group training, specifically the NN Running Team, with whom Malc has been working in Kenya.

 

Malc originally moved to the area because a research and development center for Garmin is located in Cochrane. Malc’s wife worked as a wireless developer for Garmin and Malc did some consulting and testing work on wearable running technologies.

Over the years, Malc has worked as a consultant for a number of companies and groups.

Most recently, Malc has been working in Kaptagat, Kenya with NN Running, the training group with which marathon world record holder, Eliud Kipchoge, trains.

Malc discusses some unique features of the group that help make it so successful:

  • Everyone accepts the process.
  • Everybody does their job.
  • They don’t burden themselves with over analysis.
  • Often in training, the superstars are in the middle and not out front pushing the pace on every run.
  • There are no secrets.
  • The training is essentially the same workouts on the same days every week.
    • The track workout happens on one day.
    • The fartleks happen on another day.
    • The long run happens at another day.
  • This routine helps make recovery predictable and manageable.
  • They just consistently do the work and consistently recover from the work.
  • The altitude and dirt roads help, but the group mentality is what really sets NN Running apart.
  • Running camps are almost military style and foster camaraderie.
  • When not running, the athletes are fine doing nothing.
  • One key to success is recovering from hard work.
  • The group dynamic is one of constructive interference.

Malc relates his experience as an elite climber to trusting one’s teammates or coach. The stakes in climbing are extremely high. There is no middle ground. You’re trusting your life with a person hundreds of thousands of times in one trip.

Jacob describes some of the groups of athletes with whom he has worked and how important trusting the process, trusting the training, trusting your teammates, and trusting the coach can be.

Intro to the Art and Science of Running Podcast



In this episode of the The Art and Science of Running, coaches Malc Kent and Jacob Puzey share their histories as athletes and coaches in the sport of running.
 
Jacob began running in middle school to get in shape for basketball. He ran in high school in the state of Oregon, USA before walking onto a Junior College Cross Country team at Ricks College where he was part of 2 x National Championship Team.
 
Even at 18, Jacob noticed differences in coaching styles between his high school and college coach. After a 2 year break from running and university studies, Jacob resumed his studies and began volunteer coaching and learned everything that he could from myriad mentors and books.
After a few years of pre-medicine and Exercise Science course work, Jacob gravitated toward the humanities and social sciences – cultural studies, anthropology, world languages, linguistics, language learning, and biolinguistic revitalization, etc.
During this time, Jacob coached high school teams and athletes throughout rural America to their first state track and cross country team and individual titles. He was also actively training and racing toward his own athletic goals and coaching other adults on the side. He continued to learn all that he could through books, articles, mentors, and coaching certification programs.
These experiences have led Jacob to approach running and coaching through a holistic lens trying to balance both qualitative and quantitative aspects of running and life.
 
After about 10 years of coaching high school and collegiate athletes, Jacob began coaching athletes remotely under the direction of Greg McMillan and Ian Torrence at McMillan Running.
After two years at McMillan Running, Jacob started his own online coaching company, Peak Run Performance, through which he, Malc, and other professionals coach athletes of all ages, abilities, and ambitions from all over the world.
Malc started running cross country in the UK as a young kid. Gradually worked his way up to the English School’s championships as a teenager where he ran against the likes of Mo Farah. He was also a national champion in orienteering at the age of 16.
 
His analytical mind helped him outperform even those who were fitter or more athletic. Malc started strength training as a rugby player in his teenage years. He began formally strength coaching in his early 20s.
 
Malc’s academic background is in applied physics and biomechanics. He has worked the last 14 years as an applied scientist or in biomechanics or mechanics.
Malc noted a BIG turning point 8 years ago when measuring with wearable technology which allows runners and scientists to get outside lab and measure in an authentic environment.
Jacob and Malc discuss the evolution of wearable technologies from Garmin footpods and basic GPS watches to power meters.
 
Malc asks: What is your philosophy on data? Do you treat all data the same or do you value some data more than others?
 
Jacob explains that time is the number one metric he relies upon in his own training and when designing training for athletes. He details his rationale in this article: DURATION vs. DISTANCE
 
Malc discusses the gait metrics he measures when performing a gait analysis.
 
  • Power is not the best metric for runners. It has been overhyped.
  • It changes quickly & is impacted by looking at watch. It also doesn’t take into account fatigue, etc.
  • How do you adjust training to life when based on power?
 
Malc subscribes to a systems thinking in the body like Stuart McMillan of Altis, in which the body is set of complicated systems that all interact. If you change one they all have to adjust and compensate.
 
Malc recommends that athletes collect all the data possible to understand a complex system with more than one stream of data.
 
Jacob and Malc began collaborating because Malc offers a service with technology that exceeds Jacob’s training and level of expertise and there was a demand for gait analysis services that Jacob could not meet. Both have enjoyed helping athletes from all over the world.
