Zone 2 / Endurance

Zone 2 running is the heart of endurance training. It’s where your aerobic engine is built, your fat-burning efficiency improves, and your ability to run longer — and recover faster — begins. This zone isn’t about speed. It’s about time on your feet, developing consistency, and building the fitness foundation that supports everything from 5Ks to marathons. If you want to run smarter and stronger, Zone 2 is where it all starts.
