How to Improve the 3 Running Thresholds (Z2, LT, and VO2 Max), with Phil Batterson, PhD

How to Improve the 3 Running Thresholds (Z2, LT, and VO2 Max), with Phil Batterson, PhD

Phil Batterson is a competitive runner, former running coach, and the founder of Critical Oxygen. Phil has a PhD in human bioenergetics and a love for all sorts of endurance sports, from rowing to track and field and ultras. His goal with Critical Oxygen is to teach athletes and coaches how to optimize their physiology to maximize endurance performance.

This episode is important and is a repost of episode 330 from 2023.

Phil breaks down some of the complex physiology behind the three different thresholds to make it more accessible, as well as providing practical ways to apply it in training. Some of our discussion includes:

  • Phil’s journey into endurance training and exercise science
  • What physiology defines each of the three thresholds
  • How runners can determine their own thresholds
  • The importance of lactate threshold work for race preparation
  • Common mistakes when using training zones
  • How to integrate VO2 max work with cross training

Whether you like to geek out on physiology or just want to race faster, you'll learn a lot from my conversation with Phil!

Episode 22: Dear Boston Marathon Runners:

Episode 22: Dear Boston Marathon Runners:

Boston is unlike any marathon in the world. It first started in 1897 with a whopping 18 runners. In 2011, nearly 27,000 runners ran the race on “Marathon Monday,” also known as Patriot’s Day in Massachusetts. In one of the most famous stories, Kathrine Switzer finished Boston as the first woman with a race number in 1967. She registered as “K.V. Switzer” to avoid detection since women were not allowed to run at that time. When officials found out she was running, they tried to physically eject her from the race. Luckily another runner body checked the official to the ground and she was able to keep running. Her historical finish proved that women could run marathons and sparked a women’s running revolution. Race officials eventually recognized the female race winners from before they were officially allowed to compete in 1972. After Bill “Boston Billy” Rodgers, a Boston legend, won the race four times in trademark style in the 1980’s, the race has become one of the most competitive marathons in the world. With a prize purse approaching $1 million in 2011, the best marathoners in the world show up to give it their all. Showcasing the extreme competitiveness of Boston, in 2011 Kenyan Geoffrey Mutai overtook early leader Ryan Hall and crushed the last 10k to finish in a mind-blowingly fast time of 2:03:02. Yes, you read that right: the world’s fastest time is an average 4:41 mile pace over 26.2 miles. In this podcast, Jason shares some words of wisdom before you line up in Hopkinton to race the world's most prestigious marathon.

Episode 20 - Author Matt Fitzgerald on "The Endurance Diet"

Episode 20 - Author Matt Fitzgerald on "The Endurance Diet"

Diet is more important than most runners realize - and the effects of poor eating habits can derail anybody's running: If you don't eat enough, you're more prone to running injuries and won't run as quickly during races or workouts If you eat too much, you'll gain weight and running economy will suffer A sub-par diet results in poor recovery (and could result in weight gain, too) A sub-par diet also causes low energy levels outside of running But if you dial in your nutrition then performances will improve, recovery will be faster, and you'll just feel better. And I think every runner would benefit from that. To help optimize our dietary choices and approach to fueling, I invited author Matt Fitzgerald onto the podcast today. Over the last several years, Matt has been investigating the eating habits of professional endurance athletes around the world. And his findings are powerful. World-Class runners in the United Sates, top swimmers in Australia, and champion triathletes in South Africa all have one thing in common: their diet. There's overwhelming evidence from around the world - and indeed, from every type of endurance sport - that the best runners in the world all eat the same way. Matt calls this approach The Endurance Diet and outlines five foundational habits that shape how elite runners fuel their training. And on the podcast, we outline each of these habits and how you can apply them to your life. Enjoy!

Episode 19 - Dathan Ritzenhein on Strength Training and Marathon Fueling

Episode 19 - Dathan Ritzenhein on Strength Training and Marathon Fueling

Ritz has more career highlights than there are spectators at the Boston Marathon (ok maybe not but still!): 3x Olympian at the 10,000m and marathon distances Former US Record holder in the 5,000m (12:56.27) 3rd fastest American marathon time in history (2:07:47) Three-time USA Cross Country Champion Two-time Foot Locker National high-school Cross Country Champion Half-marathon PR of 60:00 (2nd best HM time in US history) A Generation UCAN-sponsored athlete, he is now preparing to run the River Bank Run 25k this May. I kicked off the episode with an embarrassing story - one I debated sharing but I thought it was funny. Enjoy! On more serious topics, we chat about: His injury prevention approach that's helped him rebound after so injuries (stress fractures, hernias, Achilles problems, and more) His favorite confidence-building workout His go-to meal after a marathon Eating pop-tarts the night before racing a marathon How his training has changed since turning pro I hope you enjoy my conversation with Dathan Ritzenhein!

Coach James Dunne on Injury Prevention for Bigger Runners

Coach James Dunne on Injury Prevention for Bigger Runners

James doesn't look like the "typical" runner - he's 6'6" and 250 pounds. A former professional rugby player, James has a degree in Sport Rehabilitation and is fully insured member of the British Association of Sport Rehabilitators and Trainers (BASRaT). He's the founder of Kinetic-Revolution and has an ongoing fascination with the functional biomechanics of running (in other words, how you move while running). In this far-reaching discussion, we talk about quite a few issues: Should overweight runners be more worried about injury? Is gaining weight more important for injury risk than being consistently overweight? Does training for weight loss differ than training for a race? How? Enjoy my conversation with James (and don't miss the announcement at the end of the show!).

Episode 16 - Matt Frazier on the Healthy Habits that Support Hard Training

Episode 16 - Matt Frazier on the Healthy Habits that Support Hard Training

Long runs, weekly mileage, and faster workouts are all important - but they won't help you improve if you don't prioritize a healthy lifestyle. Without proper nutrition, you won't have as much energy to tackle your training. Without enough sleep, recovery will be sub-par and some of your hard work will be wasted. Without reducing stress, the risk of over-training and injury increases (and you'll rarely feel good). So it makes sense to give yourself every advantage and set yourself up for success, especially if you're gearing up for a big race or attempt at a personal best. When you get these "little things" (which are not so little) right, it makes training much easier to accomplish. After all, success in running depends on the lifestyle that surrounds the training. So I invited No Meat Athlete founder Matt Frazier on the podcast. In just the last few years, Matt has implemented  a staggering number of changes to his life: He adopted a vegetarian diet - and then vegan No Meat Athlete was born and quickly became a world-wide movement He improved his marathon from 4:53 to 3:09 to qualify for Boston Not wanting to settle, he started running ultras - including a 100-miler He's given up oil and experimented with other habits like journaling, meditation, and fruitarianism If you've ever tried to start a new healthy habit, you know how difficult this can be on top of your other obligations like work and family. And I wanted to know how to make all of these "little things" easier to implement in your life. Because if you're not sleeping well, eating right, and eliminating stress the other 23 hours of the day, then running a longer distance or racing a Personal Best is going to be that much more difficult to achieve.
