KEEP

Stop guessing.
Start executing.

I am Justin Kaufmann. Six years ago I was not a runner. Now I race an ultra a month on 120+ mile weeks. That was not talent, it was a system: threshold, sweat rate, carbs an hour, bloodwork, every one of them measured. Here is the whole thing, so you can run it too.

The method

How I actually
do it.

Fueling, volume, heat, shoes, elevation, data. Six pillars, every one testable and already working for the athletes I coach. The whole system is written down in the Knowledge Corner.

The Ultra Project

12 ultras.
12 months.

I am running the system on myself all year and publishing the parts nobody posts: what hurt, what I got wrong, and what I would do differently. If it does not survive twelve ultras, I have no business teaching it.

You do not need
special talent.

You need the system, applied to your life, your mileage, and your goal race. That is the entire job. I read every application myself and the roster I can take at one time is limited.
