About this episode

This episode explores the significance of training zones 4, 5, and 6, providing insights into their physiological impact and practical training strategies.

RunDot workouts are built around your personalized training zones (calculated directly from your run test results), but what do Zones 4 through 6 really mean for your performance? This week, Coaches Brady Hoover and Ben Sommerville join us to break down the purpose and power of these higher-intensity “spicy” zones. We dive into how each zone should feel, what’s happening physiologically as you push into threshold and beyond, and why precision matters when the effort ramps up. You’ll also learn practical strategies for pacing, managing fatigue, dialing in effort, and avoiding the common mistakes athletes make when training and racing at higher intensities. If you’ve ever questioned whether you’re truly hitting Zone 4, 5, or 6, or if you’ve struggled to control the burn, this episode will give you the clarity, confidence, and execution tools to maximize every hard session and get more from every mile.
