Kate shares her full journey to becoming a content creator.

Kate and Jeremy, her soon-to-be husband, sit down to unpack the complete story of how she got to where she is today. She begins at 12 years old in Glen Rock, New Jersey, where she played lacrosse and dreamed of becoming a Division I athlete. Kate opens up about the traumatic experience of tearing her ACL twice and how losing the sport she loved forced her to pivot from her lifelong goal to a completely different path.

She reflects on her college experience, the early jobs she took after graduating, and the period of uncertainty that ultimately pushed her toward creativity. Together, Kate and Jeremy recount the moment they first imagined creating an online show and how that idea eventually grew into The Running Interview Show.

This episode follows the full arc — from childhood dreams to injury, reinvention, and the spark that led to the career she has today.

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

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
