Is Zone 2 Running Overrated? Understanding the Backlash Against and Science of Easy Running

About this episode

Zone 2 is the magic bullet for improved health and endurance fitness - or it is overrated and spikes your cortisol. You have likely encountered both claims on social media, and neither are correct. In this episode, we dive into the science of zone 2 for runners. We discuss how to set your zone 2 correctly, who should use it, who should ignore their heart rate zones, and what happens if you run slower than zone 2 on your easy runs. Whether you are a new runner or a marathoner, you will learn something from this episode!


In this episode, you’ll learn:

✅ How to use zone 2 correctly
