Zone 1 / Endurance

Zone 1 running is where endurance begins. This low-intensity zone is often overlooked, but it plays a vital role in recovery, aerobic development, and the long-term growth of every runner — from beginners to marathoners. In this zone, you build your base, develop consistency, and learn to enjoy running without pressure. Whether you're coming back from a break or building fitness gradually, Zone 1 is the foundation that supports everything else.
