From the New York Times, this is the interview. I'm Lulu Garcia Navarro.

Imagine yourself on an isolated mountain pass. The wind is whipping, the air is thin,

there's nothing around you except the sky and the sound of your feet hitting the craggy ground.

Many of us have experienced the wonder and exertion

that comes with being in the world's wild spaces.

But for Killion-Journett, it is much more than that.

Jornet is a professional ultramarathoner whose life's work is to literally run up mountains.

But even in that world of elite athletes, he is exceptional.

He holds the fastest known time for scaling Montblanc and the Matterhorn to name just a few.

He's gone up Everest twice in the space of a week,

and he did it with no supplementary oxygen and without support.

His physical stamina has been studied by researchers,

and he's pushed the limits of what is considered physically possible.

And then, just last fall, he completed his most radical adventure,

which he called states of elevation.

He climbed 72 of the highest peaks in the western United States

over the course of just a month.

And for good measure, he also cycled between all of them,

a ride totaling over 2,400 miles.

I mean, I'm exhausted just imagining it.

But as I discovered in our conversation, he also is a deep thinker who has important lessons to impart about what our bodies and minds are capable of when we push them to extremes, and the joy and danger that

effort can bring. Here's my interview with Spanish ultramarathoner, Killian Tournette.
