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.

In this episode, we sit down with renowned expert Patrick Davitt to dive deep into the science of human performance. Dr. Patrick M. Davitt is the Program Director of Exercise Physiology at Saint Joseph's University, specializing in energy metabolism and fitness testing. With a PhD in nutritional physiology and biochemistry and over 15 years of experience, he is an ACSM Fellow and CSCS-certified expert known for his research on ultra-endurance athletes and nutritional strategies.

We dive into the questions every runner has, including:

• What does it truly mean to be "fat-adapted," and is it right for you?

• Why the "eat before every run" rule isn't always necessary for all workouts.

• The ideal fueling strategies for different types of runs, from easy recovery jogs to high-intensity intervals.

• How a fat-adapted runner's race-day strategy differs from that of a carb-loader.

• Potential side effects and mistakes to avoid when changing your fueling approach.

This week on The Marathon Running Podcast, we tackle the most misunderstood phase of marathon training: the taper. Host [Insert Host Name Here] compares this final stage to the difference between cramming and consolidating for a major exam, sharing a personal story about how his own failed taper taught him the hard way that less is truly more. For solo runners like Letty, mastering the taper is especially crucial, as it’s the final step to ensure your body is primed for an independent race. We dive into the science of supercompensation, explaining how resting unlocks your full physiological potential by rebuilding muscle, replenishing glycogen, and boosting your immune system.

Whether you're battling the "taper crazies" or feeling anxious about the reduced mileage, this episode is a deep dive into the practical blueprint and mental strategies you need to arrive at the starting line feeling strong, confident, and ready for your best race. Trust the process, because the taper isn't about losing fitness—it's about unlocking it for that final, glorious solo effort.

Our guest: @ericaweitzruns

This episode of The Marathon Running Podcast is your essential guide to turning summer heat into your greatest competitive advantage. We sit down with running coach Erica Weitz to break down the science behind how summer training is the secret to a breakthrough fall racing season. Coach Weitz explains the critical physiological adaptations that happen when you train in the heat, such as increased plasma volume and improved thermoregulation, and how these directly translate to a more efficient and powerful performance on a cooler race day. We discuss the strategic role of a summer training block within an annual plan—is it a base phase, a specific prep phase, or a nuanced combination? You’ll also learn which metrics she monitors to ensure athletes are successfully building the resilience needed for a strong fall performance, and her evidence-based strategies for safe and effective heat acclimation.

Beyond the physiology, Coach Weitz delves into the practicalities of transitioning from summer endurance to fall speed. She outlines the typical progression of intensity and specificity that prepares an athlete for the demands of a goal race, from building an aerobic engine to integrating race-specific paces without risking overtraining. We also discuss the often-overlooked role of strength and conditioning in summer for preventing breakdown and enhancing power for faster fall paces. Finally, Erica shares her philosophy on how to cultivate the mental fortitude gained from the "summer grind" and avoid common pitfalls as excitement for fall races builds, ensuring you show up to the start line physically and mentally prepared for your best performance.
