How Fast Should You Run?

Runners ask me all the time how fast they should run for various types of workous — easy runs, tempo runs, intervals. Most runners run either too fast or too slow to obtain the desired result. To determine the correct speed, you must know the purpose of each workout. Always remember that the goal of […]

Einstein, Pyruvate, and Simplicity

I am often asked how to become a better runner. The answer is simple… and complex. As Albert Einstein said, “Everything should be made as simple as possible, but not simpler.” So, in honor of Einstein (whom I share a birthday with), here is a simple explanation of how to become a better runner.

She was referring to how to train middle distance and distance runners — with lots of speed training or lots of endurance […]

One of the first scientific questions I had at a young age was how a baseball pitcher throws a curveball. It’s so cool how pitchers exploit the physics of aerodynamics to make the ball […]

A Conversation with an Olympian and the Gum He Chews

What do you get when you cross a stick of gum with caffeine and an Olympian? You get Run Gum, the creation of Olympic 800-meter runner Nick Symmonds, whom I had the pleasure of speaking with via Skype this week. For those of you who don’t follow track and field, Nick Symmonds is a bit […]

Bows and Arrows, Baby Stroller, and Potential Energy

This stored energy by virtue of changing its position is called potential energy. When the arrow is released from the bow, that potential energy is […]

Talent, Fate, and Marionettes

On my run today through beautiful Torrey Pines and Del Mar, California, I thought about finding talents.    Ever wonder if you’ll ever find out before you die what your real talent is? How are we supposed to find it? Does fate really exist and, if so, does it lead us to the endeavors we’re […]
