We sit down with Arj Thiruchelvam, performance coach at Performance Physique, to dissecta groundbreaking new study from Loughborough University that is changing how we view the "marathon wall." We ask the tough questions: Why do we collapse in the final 10K? Is it a lack of cardio, or something deeper? Arj breaks down the science of "durability" and explains why heavy lifting and plyometrics are the missing link for well-trained runners looking to maintain their economy under extreme fatigue.

Why You Should Listen: You will learn why a 35% increase in time to exhaustion is possible through strength training and how to implement "bouncy" exercises like drop jumps to transform your running gait.

In this episode of the Marathon Running Podcast, updates and expert insights to keep you informed on the latest in running and competitive sports. We sit down with Arj Thiruchelvam, performance coach at Performance Physique, to discuss a brand-new study from Nature Scientific Reports that used machine learning to compare polarized and pyramidal training. We ask Arj why some runners thrive on threshold work while others need to "polarize" to see progress. Arj breaks down the 30% performance gap found in the study and explains how your training age determines your ideal intensity mix.

Why You Should Listen: You will learn the difference between polarized and pyramidal distributions and how to use machine learning insights to personalize your own marathon training plan for maximum speed.
