Hello, folks. Welcome back to the Whoop podcast, where we sit down with The Best of the Best.

I'm your host, Will Amid, founder and CEO of Whoop, and we are on a mission to unlock human performance.

That's right. All right, this week's episode, we have a very, very special athlete, special in the sense that he is a world-class ultra-marathoner and a data scientist.

painful events. John gets into a lot of that, balancing the sense of community and competition.

And we talk a lot about John's whoop data. He's been wearing whoop for a long time, and we talk

about some of the crazy data he has as he does these
