Threshold

One athlete. Nine disciplines. The space between them.

thresh·old

/ˈθreʃ.hoʊld/ · noun

  1. The point where something begins to change.
  2. The edge between what you can do, and what you can’t — yet.

Threshold Theories is my project. It began as a question I asked in every sport I tried: where exactly is my limit, and what happens if I stay there a little longer?

Every discipline gave me a different answer. Here I write those answers down as theories, and test them on the longest threshold I know: endurance.

The theories

Three ideas I live by

  1. Theory I

    Every sport is a threshold.

    Taekwondo taught me control, skating gave me speed, parkour made me adapt and swimming taught me efficiency. Each one was a door I walked through, and each one changed how I move.

  2. Theory II

    Endurance lives at the edge.

    Marathon and ultra distance are the longest thresholds I know: hours spent right on the line between holding on and letting go. That is where I am training now.

  3. Theory III

    No one crosses alone.

    Coaches, family, friends and communities like Sepas Collective have carried me this far. Threshold Theories is built to share the edge, with supporters today and with a team soon.

The athlete

I’m Emad Karami

I have been moving since I was three: nine disciplines, from taekwondo mats to mountain snow.

I’m the first test subject of Threshold Theories. Every chapter so far has been preparation for the one I’m in now: marathon, and then ultra distance.
