Are your running shoes "dead" at 500 miles? Many runners lose sleep over the famous mileage rule, treating it as a non-negotiable expiration date. In this episode, we deconstruct the infamous 300 to 500-mile myth and expose how the running industry's business model of planned obsolescence has influenced this idea. We'll dive into the real science of shoe breakdown—from midsole compression to a runner's unique biomechanics—to uncover why a one-size-fits-all mileage rule is deeply flawed.

Instead of a number, we give you the practical tools to know when a shoe is truly worn out. Learn the key signs of fatigue and discover why your body is the ultimate sensor for shoe health. We also explore the proven benefits of a shoe rotation for extending the life of your gear and reducing your risk of injury. Join us to change your mindset, save money, and gain a new perspective on your most essential piece of running equipment.

Have you ever been lucky enough to get into two major marathons in one season, like Sydney and Chicago or Berlin and New York? It's a great problem to have, but it presents a unique challenge: how do you train for and race both?

On this episode, I'm joined by running coach Chris Knighton, who shares his expert advice on tackling this marathon double. We discuss the A-Race and B-Race strategy, the importance of prioritizing recovery, and the mental and physical considerations of running two marathons within just a few weeks of each other. Coach Knighton also gives his perspective on why dropping out of a race can sometimes be the smartest move and the best ways to deal with jet lag and recovery.

Whether you're doubling up on races or just looking to improve your recovery game, this episode is packed with valuable insights you won't want to miss.
