326. Marathon 101 Masterclass (Part 1 of 4) — The Aerobic Engine & Training Blueprint

<p>In this episode, we launch our four-part Marathon Masterclass designed to strip away overcomplicated training noise and get back to core physiological fundamentals. Whether you are tackling your first 26.2, targeting a Boston Qualification, or resetting ahead of a new training block, we lay out the exact blueprint for setting up a successful 16-to-20-week macrocycle. We break down the medical and orthopedic reality of tissue adaptation, explain why muscle strength outpaces tendon durability, and outline the pre-block readiness audit every runner should pass before starting Week 1.</p><p>We also dive deep into the science of the aerobic engine and why 80% of your training volume must feel effortless. Discover how Zone 2 running drives capillary expansion, mitochondrial biogenesis, and fat oxidation—and why falling into the &quot;Gray Zone&quot; (Zone 3) traps runners in cumulative fatigue. Plus, we share half-marathon prediction formulas to calculate a realistic race goal, explore the 3:1 build-to-recovery microcycle pattern, and discuss when it makes sense to work with a running coach.</p><p><strong>Show Notes &amp; Links Mentioned:</strong></p><ul><li><p><strong>Full Article &amp; Breakdown:</strong> Read the accompanying guide on <a href="https://marathonjournal.com" target="_blank" rel="noopener">MarathonJournal.com</a></p></li><li><p><strong>Pacing Tools:</strong> Check your training zones using the <a href="https://vdoto2.com/calculator/" target="_blank" rel="noopener">VDOT Running Calculator</a></p></li><li><p><strong>Get in Touch:</strong> Questions or topic requests for Part 2?
