The thinking coach's guide to training that actually works.

I spent years coaching high school distance runners and watching smart coaches borrow workouts from the internet without a framework for evaluating them. Good workouts in the wrong context don't work. And most coaches don't know why.

Run By Numbers is how I fix that. It's a methodology — a system of 23 questions that forces you to think through what you're building, why it works, and how to know if it's working.

The tools here are built on that same framework. Use them to check your instincts, stress-test your workouts, and build training your athletes will actually respond to.
