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.
