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 do you do when you achieve everything you set out to accomplish — and it still doesn’t feel like enough?

Allyson Felix is the most decorated track and field athlete of all time: 11 Olympic medals. 5 Olympic Games. But the most important lesson of her career had nothing to do with winning.

In this episode, Allyson opens up about:


the grief of losing the identity you’ve built your life around


what it really felt like to win silver when the world expected gold


training at 4am in the dark while pregnant to hide it from sponsors


the New York Times op-ed that forced Nike to change maternity policy


and the moment she stopped tying her worth to her results

Whether you're chasing a goal right now — or wondering what comes after you reach it — this conversation will change how you think about success, identity, and what you're really running toward.
