Would Longer “Weeks” Make Your Training More Manageable?

By Matt Fitzgerald | September 28, 2020

Originating in ancient Samaria more than 4,000 years ago, the seven-day week has become a standard calendrical feature throughout the world. Most athletes in most sports adhere to this convention as well. I recall noting this during my time with the HOKA Northern Arizona elite professional running team in 2017. Unlike the majority of us, […]

Fifty Is the New Whatever

By Matt Fitzgerald | September 19, 2020

The 2020 Antrim Coast Half Marathon was exceptional simply by virtue of happening. It was one of the first sizeable road running events to take place after the COVID-19 pandemic swept the planet. But the race became even more exceptional when 60-year-old Irishman Tommy Hughes crossed the finish line in 1:11:09, smashing the age-group world […]

What Gets Measured Gets Overemphasized

By Matt Fitzgerald | September 14, 2020

Recently I created a custom training plan for an Italian ultraendurance cyclist who was preparing for a pair of multiday, multi-thousand-kilometer bike tours, and who told me in the onboarding questionnaire he submitted that increasing his functional threshold power (FTP) had been a major point of emphasis in his training. For the runners in the […]

Mindful Eating

It’s Not About the Food (It’s How You Think About Food)

By Matt Fitzgerald | September 5, 2020

Recently I had the opportunity to read a prepublication copy of a book by Bryan Green, who ran with Meb Keflezighi at UCLA and now cohosts (along with retired elite middle-distance runner Jon Rankin) the Go Be More podcast. Titled Make the Leap, the book is based on the premise that, as Green puts it, […]

Goal-Directed, Principle-Guided Experimentation

By Matt Fitzgerald | August 31, 2020

I’m working on a new project involving artificial intelligence and endurance training that I could tell you about, but I would have to kill you. Just kidding—it’s not that secret. In any case, the project has got me thinking about fundamental questions in endurance training. For example: What is training? Don’t snicker. The answer is […]

Here’s a Fun, Fast New Workout to Try: Decreasing Intervals

By Matt Fitzgerald | August 22, 2020

These are exciting times to be an endurance training geek. We seem to have entered a new period in which exercise scientists are taking the lead in coming up with innovative new workout formats. It makes sense. For many decades, humanity knew so little about how to train optimally for endurance performance that the majority […]

Repeat After Me: “I’m Injured and I Couldn’t Care Less”

By Matt Fitzgerald | August 17, 2020

Currently I’m reviewing the copyedited manuscript of my forthcoming book The Comeback Quotient: A Get-Real Guide to Building Mental Fitness in Sport and Life, which is available for preorder. (Subtle, eh?) Chapter 6 tells the remarkable story of Jamie Whitmore, a dominant professional off-road triathlete in the 2000’s who later overcame a Jobian cancer ordeal […]

Got a Comfortable Training Routine? Good—Change It!

By Matt Fitzgerald | August 10, 2020

Leon Fleisher died recently. Man, what a life! Born in San Francisco in 1928 to Jewish immigrants, he started playing the piano at age four, and by nine he was proficient enough to become a student of renowned teacher Artur Schnabel. At 16, Fleisher made his Carnegie Hall debut, and by his mid-20s he was […]

As an Athlete, Should You Care What Others Think? (Hint: All One-Word Answers to This Question Are Wrong)

By Matt Fitzgerald | August 3, 2020

In March 2017, I gave a talk at Run Flagstaff, a running specialty store located in the city whose name it carries. During the talk, I mentioned an occasion when I got to hang out with 2:19 marathoner Yoko Shibui and her teammates on the Mitsui-Sumitomo women’s professional running team in boulder, Colorado. “Are there […]

John Calvin

Are You a Chosen One?

By Matt Fitzgerald | July 27, 2020

This article is about endurance sports, I promise. It’s just going to take a minute to get there. Are you familiar with Calvinist doctrine? At its heart is the concept of predestination. Calvinists believe that, at the beginning of time, God selected a limited number of souls to grant salvation and there’s nothing any individual […]
