Are you stuck in a cycle of running injuries, overtraining, and rigid marathon training plans that leave zero room for real life? It's time to change the way you chase your next running PR.

This week, we sit down with sports scientist and 2:28 marathoner Josh Sambrook, creator of the adaptive running app Kaizen. Josh drops a major truth bomb on standard running coaching dogma, explaining why traditional 16-week schedules fail amateur athletes and how shifting to a dynamic training load model eliminates the guilt of missed miles. We deep dive into the exact marathon racing math that allows his algorithm to predict finish times with a staggering 93% accuracy. Plus, he shares a controversial, data-backed hot take on why busy runners should stop wasting precious time on gym work and strides, and focus purely on aerobic base building through high-volume slow running to unlock their absolute fastest potential.

If you want to master marathon pacing, prevent running injuries, and execute a flawless marathon strategy on race day, this episode is your blueprint.
