There Is No Off-Season: How to Train Through the Winter

Every year, I get the same question from athletes: “What should I do in the off-season?” Here’s the truth: there is no off-season. There’s only a transition phase. As training for ultrarunning is a chronic, not an acute...

Lessons from Aid Stations

Fast(er) After 50?

How to Design Big Increases in Volume

When it comes to training for ultras, volume is king. While I’m an advocate of smart and periodized intensity training, there’s no substitute for big weekly volume and time-consuming long runs. But how much is too much a...

Anti-Doping Efforts in Ultrarunning

While trail and ultrarunning will certainly go through some bumps and bruises as this patchworked anti-doping system comes to light, let me make one thing clear: the ultimate responsibility is on the athlete and there are no excuses.

High Performance Coaching

TAs my coaching career has progressed over the years, I’ve begun to have more appreciation for coaches who are Jacks (and Jills) of all trades, yet masters of none. We know (or at least should know) just enough about phy...

Training With Artificial Intelligence

Artificial Intelligence (AI) is coming to trail and ultrarunning and when it does, it will be here to stay. Regardless of your initial impression of the technology, if you are a power user of Chat-GPT, have interfaced wi...

Using Lactate Testing to Inform Training

As athletes gear up and recalibrate their training during the fall and winter months, it’s a good time to use physiological testing as a window into your strengths and weaknesses to help make training decisions.

Is Trail Running Economy Worth Improving?

In road running, running economy matters—a lot. So much so, that marathoners will do anything to optimize it. This was epitomized by Eluid Kipchoge’s two attempts at breaking the 2-hour marathon mark. During those att...

How to Find Your "Why"

How Young is Too Young?

There is much debate about young runners and how much running one should do before puberty. There are many sides of the fence in this deliberation. So, as we deliberate and arbitrate for an ultimate decision, let’s offer up some philosophical points of view on athlete and human development based on the most common questions I get from parents.

How Young Is Too Young?

I ran my first marathon when I was 13. At the time, I thought it was somewhat of a novelty. I knew few people my age that would run such a feat. And like all teenagers, I succumbed to the scope of my own neighborhood...

Three Training Runs to Add to Your Routine

Sometimes just finding where to run can be a chore. The mental ping-pong game between doing something easy or designing an elaborate route can derail even the best intended ultrarunners. Over the course of my running life, I’ve learned that dividing the runs I do into three discrete buckets helps me with the chore of deciding where to go and what to do.

Three Principles of Creating a Long-Range Plan

When I look back at a year’s worth of training and racing for any athlete, inevitably, one common theme emerges. The athletes who reaped the most success during the year were also the athletes that planned out their t...

Karl Meltzer’s Training

Retool Your Running Mechanics: Transition to the Outdoors

In part one of this series, we started with a home-based strength and coordination program to lay the platform for a stronger and more capable runner.
