Training science, coaching, and the 80/20 method — from Matt Fitzgerald and the 80/20 Endurance coaching team.

  • How Sex Can Make You a Better Runner

    Let me start with an apology. This post is not about sex. It’s actually about hermeneutics, or the discipline of textual interpretation, as it applies to endurance training. I knew that if I promoted a post about hermeneutics on social media, no one would read it, so I deliberately mislead you. Dastardly, I know, and…

  • Would Longer “Weeks” Make Your Training More Manageable?

    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

    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

    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…

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

    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

    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

    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”

    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!

    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…
