Heart Rate Zones for Running: How to Find Yours

Heart rate zones give you a simple way to control effort. You can build endurance in low zones, improve threshold in mid zones, and develop speed in higher zones.

Estimate Your Max Heart Rate

Simple estimate: Max HR = 220 − age

This is a rough estimate. Field tests or lab testing are more accurate, but this works for a practical starting point.

Zone Breakdown

  • Zone 1 (50-60%): Recovery
  • Zone 2 (60-70%): Aerobic base
  • Zone 3 (70-80%): Tempo endurance
  • Zone 4 (80-90%): Threshold
  • Zone 5 (90-100%): VO2 max

How to Use Zones

Build most weekly mileage in Zone 2, add one threshold session in Zone 4, and use Zone 5 for short intervals. The mix keeps training balanced.
