Did You Get Enough to Eat?

By Matt Fitzgerald | February 19, 2018

Eating too much is a widespread problem in America. That’s why more than 70 percent of men and women over the age of 20 are overweight or obese. And while there are plenty of clowns running around blaming individual nutrients or food types for these numbers, the simple fact is that overweight and obesity are […]

The Joy and Utility of Multi-Pace Workouts

By Matt Fitzgerald | February 12, 2018

Most runners target a single intensity in all of their workouts. Either it’s an easy run or long run at a slow and steady pace or a tempo run with an effort at lactate threshold intensity sandwiched between a warm-up and a cool-down or an interval session featuring a set of a certain number of […]

Decision Theory and Racing Weight

By Matt Fitzgerald | February 5, 2018

Regular readers of this blog are probably sick and tired of hearing me yammer on and on about the differences between professional and recreational endurance athletes. But that’s my shtick. I’m all about helping recreational athletes improve by doing things more like the pros. Not all of the differences between elites and age-groupers are methodological. […]

It’s Only Pain

By Matt Fitzgerald | January 29, 2018

During the 13 weeks I spent training with the NAZ Elite professional running team in Flagstaff last summer, I did a few workouts with Sarah Crouch, not a member of the team but an accomplished pro with a 2:32 marathon on her resume. During a couple of these sessions, it was apparent to both of […]

Why I Try to Talk Every Endurance Athlete Who Does CrossFit or Is Interested in Doing CrossFit out of Doing CrossFit

By Matt Fitzgerald | January 22, 2018

These days lots of endurance athletes are supplementing their endurance training with CrossFit workouts, or are interested in doing so. Whenever one of these athletes comes to me for coaching, I try to talk him or her out of it. I do this not because I think CrossFit is intrinsically bad or because I believe […]

Why Attention to Detail Is the Enemy of Healthy Eating

By Matt Fitzgerald | January 15, 2018

As a sports nutritionist, I observe the diets of lots of endurance athletes. After more than a decade of doing so, I can say that perhaps the most important pattern I’ve noticed is that athletes whose diet is consistently working for them (i.e., delivering the results they seek) pay relatively little attention to the details […]

What Is Good Running Form?

By Matt Fitzgerald | January 8, 2018

If you ask the average running coach what good running form is, he or she will probably answer with phrases like “midfoot strike,” “high stride rate,” and “low vertical oscillation.” It is true that these and other form characteristics are common in top runners and less common in slower runners. But there are exceptions. Meb […]

What I Learned about Strength Training as a Member of a Professional Running Team

By Matt Fitzgerald | January 1, 2018

The strength-training methods I use today are different from those I practiced before I spent 13 weeks as a guest member of Hoka One One Northern Arizona Elite, a professional running team, in the summer of 2017. It’s not that I lacked commitment to strength training prior to this experience. As a self-coached athlete I […]

On the Limits of Science as a Guide on How to Train

By Matt Fitzgerald | December 26, 2017

There is virtually no evidence from controlled scientific studies that high-volume training is optimal for developing endurance fitness. High-volume training is optimal for developing endurance fitness. Both of the above statements are true. The reason there is virtually no evidence from controlled scientific studies that high-volume training is optimal for developing endurance fitness is that […]
