What kind of person runs 1,000 kilometers in 12 days – twice? Meet Natalie Dau, a Guinness World Record holder who doesn't just push the limits of human endurance — she redefines them. Cal dives deep with Natalie to uncover how she uses pain as fuel, movement as a message, and her voice — amplified by AI — to raise money, shift perspectives, and help people live better lives.

It's about resilience, purpose, technology and inequality -- and what happens when they all collide. Listen now. Share widely. The world needs this story.
