Calculate your optimal heart rate for running based on pace and fitness level
Monitoring your heart rate during running helps optimize training intensity, improve performance, and prevent overtraining. This calculator helps you understand the relationship between your pace and heart rate.

| Zone | Heart Rate | % of Max | Training Benefit |
|---|
| Zone | Intensity | % of Max HR | Benefits |
|---|---|---|---|
| Zone 1 | Very Light | 50-60% | Recovery, warm-up, cool-down |
| Zone 2 | Light | 60-70% | Endurance, fat burning, aerobic base |
| Zone 3 | Moderate | 70-80% | Improved aerobic capacity, endurance |
| Zone 4 | Hard | 80-90% | Lactate threshold, speed endurance |
| Zone 5 | Maximum | 90-100% | Maximum performance, anaerobic capacity |
Heart rate responses vary between individuals. These calculations provide estimates based on general formulas. For personalized training guidance, consider consulting with a coach or sports physician.
The relationship between your running pace and heart rate is a key indicator of your cardiovascular fitness and running efficiency. Understanding this relationship can help you optimize your training and improve your performance.
Train in Zones 1-2 (50-70% of max HR) to build aerobic endurance and improve fat metabolism. These "easy" runs should make up 70-80% of your training volume.
Train in Zone 4 (80-90% of max HR) to improve lactate threshold. These "comfortably hard" efforts help you sustain faster paces for longer periods.
Train in Zone 5 (90-100% of max HR) for short intervals to improve VO2 max and anaerobic capacity. These high-intensity efforts should be limited to 1-2 sessions per week.
Remember that heart rate has a lag time and doesn't respond instantly to changes in effort. When starting a run or changing pace, give your heart rate 1-2 minutes to stabilize before using it as a guide.
