📊 Heart Rate Zones for Cycling

Training by heart rate zones is the foundation of structured cycling training. The 5 classic zones are:

Zone 1 (50–60% max HR): Active recovery — easy rides
Zone 2 (60–70% max HR): Aerobic base — the most important zone for endurance cyclists
Zone 3 (70–80% max HR): Pace — sustained effort in a group or time trial
Zone 4 (80–90% max HR): Threshold — improves FTP and climbing performance
Zone 5 (90–100% max HR): VO2 max — high-intensity intervals
