Aerobic Threshold and the Benefits of Zone 3 with John Davis, PhD

Aerobic Threshold and the Benefits of Zone 3 with John Davis, PhD

In today's running culture, people can't stop talking about Zone 2 running. But what about Zone 3?

John Davis is an author, running coach, former collegiate runner, and an expert in human performance with a focus on biomechanics.

He ran at Carleton College before getting a PhD in biomechanics at Indiana University's School of Public Health, focusing on running injuries.

In this episode, we talk about:

  • The underutilized value of Zone 3 running

  • Why zones aren't as clear as many people make them out to be

  • Lactate threshold and steady-state max in running

  • High-end aerobic training and its effects on muscle fatigue

  • Improving aerobic capabilities with middle intensity training

  • Main drivers of fatigue in different intensities

  • Training in Zone 3 and how it can predict performance in endurance events

  • Balancing physiological principles with practical coaching

Send this to your running group chat so you can unpack the myths and science behind Zone 3 on your next group run!

After resisting most supplements for the better part of my life, I'm cautiously changing my tune. I'm now a Masters runner and in my personal life, I'm optimizing for longevity. I want to be my healthiest self for as long as possible and I'm excited to partner with Previnex to make that happen.

Muscle Health Plus will help you prevent muscle damage, which is particularly important for aging runners who want to protect themselves from muscle loss and recover faster after hard workouts.

Thank you MOBO Board!

Invented by renowned physical therapist Jay Dicharry, MOBO helps you stabilize your stance with an innovative rocker board that's set up on two fins. The design effectively forces you to drive your big toe into the board to improve your stability. I was pretty arrogant going into my first session on the MOBO Board. How hard can it be to balance, right? Well, I was humbled pretty quickly!

Even if you're a good runner, better balance, stability, and proprioception is going to help you have a more powerful stride and prevent more running injuries. You'll learn how to improve the efficiency of the kinetic chain from your hip to your big toe. Because as Jay likes to say, it's not just how strong you are, but how well you use that strength.

I was recently at a weekend physical therapy workshop (lol I was the only running coach) and learned how important (and rare) this simple movement is. Save 10% with code STRENGTHRUN10 at checkout at moboboard.com.

Episode 3: Shalane Flanagan on Morning Routines, Unfinished Business and Writing a NYT Best-Seller

Episode 3: Shalane Flanagan on Morning Routines, Unfinished Business and Writing a NYT Best-Seller

Born in the coastal town of Marblehead north of Boston, Massachusetts, Shalane showed an early aptitude for distance running. A three-time All-State cross country athlete, she also finished first in the state in the mile and her 4:46 performance won the National Scholastic Indoor championships. Her two-mile performance still stands as a Massachusetts record. Flash forward to to 2004 when Shalane turned professional and her achievements kept piling up. A two-time national champion in the 5,000m, she won the short course cross country championships in 2004 and 2005. Today, Shalane is one of the most dominant female distance runners on the planet, boasting achievements like: 2008 Bronze Medalist in the Olympic 10,000m Multiple American Record holder 2nd fastest American female marathoner of all time with a 2:21:14 personal best 2012 Olympic Trials marathon winner and 10th overall at the 2012 London Olympics 6th overall at the 2016 Rio Olympics in the marathon But Shalane isn't just a runner. She's now a New York Times best-selling author with her coauthor Elyse Kopecky of Run Fast, Eat Slow: Nourishing Recipes for Athletes. This was one of the easier interviews I've ever done because Shalane is so easy-going and relaxed. I had a blast talking to her about a wide range of subjects: Does Shalane have a Boston accent after a few glasses of wine? Her favorite type of wine Go-to runs in the Boston area What does running 120 miles a week feel like? A snapshot of her strength training program Why she now loves fat - after avoiding it for years Her favorite race What's next for Shalane (this might be surprising)

Episode 1: Nick Symmonds on Becoming an Olympian and Starting Run Gum

Episode 1: Nick Symmonds on Becoming an Olympian and Starting Run Gum

Nick Symmonds is one of the world's best middle distance runners. A two-time Olympian and 2013 silver medalist at the World Championships, he has a personal best time of 1:42.95 in the 800 meters (and a 5:19 beer mile PR!). An outspoken advocate for athletes rights, his company Run Gum has sued the US Olympic Committee and USA Track & Field to help track athletes better market themselves. Considering that more than 50% of elite track and field athletes live under the poverty level, this would dramatically help them land more sponsorships and make a better living. In this far-ranging conversation, Nick and coach Jason Fitzgerald talk about everything from Tesla and SpaceX, auctioning off ad space on Nick's shoulder to the highest bidder, what it feels like to perform on the world's biggest stages, and starting his performance running gum company Run Gum.
