Post Run High

Post Run High is a podcast about honest conversations that happen when people slow down and let their guard drop.

Hosted by Kate Mackz, the show brings together founders, creators, athletes, artists, and thinkers to talk about performance, identity, pressure, and the moments that shape who we become. Recorded after a run, walk, or shared movement, these conversations tap into the clarity that often comes when the body is tired and the mind is open.

This isn’t a show about success on paper. It’s about what people carry behind the scenes — how they cope with doubt, navigate change, stay disciplined, and keep going when things get hard. Post Run High is a space for reflection, perspective, and real insight you can take into your own life.

What if becoming wildly successful didn’t feel the way you thought it would?

Lucy Guo became the youngest self-made female billionaire in the world — but what she learned about money, ambition, and identity might surprise you. As a co-founder of Scale AI she (an AI unicorn) she shares her thoughts on AI and how to best prepare yourself for what is coming.

In this episode, we talk about what it actually takes to build something at the highest level, why money doesn’t solve the problems you think it will, and how your environment, network, and willingness to take risks shape everything.

Lucy shares the realities behind building billion-dollar companies, the pressure that comes with success, and why some of the most important decisions have nothing to do with intelligence — and everything to do with how you think.

If you’ve ever felt behind, questioned your path, or wondered what it really takes to “make it,” this episode will change how you see success.
