Try the 80/20 Endurance Pacing Challenge!
Think about the last race you completed. Could you have gone any faster than you did? It’s a very simple question, yet a difficult one to answer in many cases. If you committed a major error in execution, such as running an entire track race in lane three, then it’s easy to answer in the […]
Why I Wrote an Entire Book on Run Pacing (and Why You Should Read It!)
I enjoy seeing any sport performed at an elite level—even golf, which I’ve never played. When I tune into a television broadcast of a professional golf tournament I am amazed by the players’ control of the ball. If a caddie tells a player they’re 185 yards from the flag on their second shot of a […]
Advancing in Another Direction: The Difference Between Retreat and Defeat
In late November 1950, at the height of the Korean War, United Nations troops under the command of Major General Oliver Smith were encircled and attacked near the Chosin Reservoir by a vastly larger Chinese force. Facing total annihilation if they tried to hold their ground, Smith’s men instead executed a fighting withdrawal, puncturing the […]
Is Lactate Measurement Essential for Endurance Training Optimization?
Lactate is having a moment. Our metabolite du jour owes its newfound celebrity largely to the hoopla surrounding the recent success of certain elite Norwegian endurance athletes, most notably triathlete Kristian Blummenfelt, who won the 2020 Tokyo Olympic Men’s Triathlon (held in 2021) and the 2021 Ironman World Championship (held in 2022), and who holds […]
A Zone By Any Other Name Would Be Complete
I recently had an e-mail exchange with an athlete regarding training intensity zones. He wanted to know how he could merge the industry standard Zone 1 definition of 50-65% of maximum heart rate into the 80/20 Endurance zones. This was news to me, because after more than thirty years participating in endurance sports this was […]
Art Versus Science in Coaching
“These other young coaches have their science blah blah but they are not as successful.” —Coach Hailye, Out of Thin Air There’s an endurance coach I follow on Twitter who tweets a lot. We’ll call him Dick Smart. I find him quite impressive on one level. A real numbers guy, he knows more about using […]
Coaching Mastery
What is the job of a coach? At the most basic level, it is to help athletes achieve their goals. Sounds reasonable, no? But the problem with this definition of the coach’s role is that it treats athletes’ goals as givens—as things that athletes come up with on their own and bring to coaches for […]
Book Review: Scientific Training for Endurance Athletes
When I was a younger man I used to shake my head in pity when reading the writings of endurance sports experts of a certain age. They tended to repeat the same things over and over, evidently because they had nothing new to say. Because they hadn’t learned anything new about their field of expertise […]
Let’s Clear Up the Irrational Thinking Surrounding Fasted Workouts
Among the benefits of traveling internationally is that it gives you a different perspective on your own country. For example, in 2015 I spent two weeks in Kenya conducting research for my book The Endurance Diet, and it was there that I came to fully appreciate how screwed up America’s relationship with food is. As […]
Training with a “Whatever Works” Mindset
In a recent blog post I mentioned that highly successful endurance athletes have a “whatever works” mindset. Today I’d like to expand on this concept and contrast it with a phenomenon that I call means attachment, which is common among less successful athletes. As the name suggests, means attachment entails becoming attached to particular means […]
