Zone 2 running is a myth

The claim that "Zone 2 running is a myth" can be broken down into two components: first, whether Zone 2 running as a training concept exists and has physiological validity; second, whether the popular understanding and application of Zone 2 running is accurate or flawed. Evidence from multiple sources shows that Zone 2 training corresponds to a specific heart rate or effort zone, typically around 60-70% of maximum heart rate, where the body primarily uses fat as fuel and improves aerobic capacity.strengthrunning.comstrengthrunning.comZone 2 Running Masterclass: When & When NOT to Run in Zone 2

This training zone is well-established in exercise physiology and endurance training literature. However, many sources highlight that people often misunderstand what Zone 2 means in practice.
