In this powerhouse episode recorded backstage at the Health Optimisation Summit, Zane sits down with the legendary Brad Kearns—former professional triathlete, bestselling author, and now world-ranked track athlete in the over-60 division. Brad shares how he ran a 60-second 400-meter sprint just days after turning 60 and what he's learned about fueling, training, and recovery along the way.

From debunking diet dogma to breaking down the difference between HIIT and real sprinting, this episode is a deep dive into how to train smarter, not harder as you age. Brad opens up about his personal journey from restrictive ketogenic eating to a more intuitive, performance-based diet—think red meat, fruit, and nutrient density over macros and restrictions.

He and Zane discuss why elite athletes don’t use restrictive diets, the misunderstood role of glucose, and how to use sprinting to turn your body into a fat-burning machine long after the workout ends. This conversation is packed with clarity, laughs, and truth bombs that will leave you questioning everything you thought you knew about longevity, health, and fitness after 50.
