For most people, a normal heart rate while running is roughly 50–85% of their estimated maximum heart rate, depending on how hard they’re working and their fitness level. What’s “good” is very individual, so ranges and how you feel matter more than one perfect number.

Quick Scoop

  • A common rough formula for maximum heart rate is 220−age220-age220−age in years.
  • For moderate runs, many guidelines suggest staying around 50–70% of that max.
  • For hard/tempo or interval efforts, 70–85% (sometimes a bit higher in short bursts) is typical for healthy people without heart conditions.

Typical Target Ranges by Age

These are example target heart rate ranges for general cardio exercise (not medical advice), often cited by heart-health organizations.

Age Approx. max HR (bpm) Moderate run (50–70%) Vigorous run (70–85%)
20 200 100–140 140–170
30 190 95–133 133–162
40 180 90–126 126–153
50 170 85–119 119–145
60 160 80–112 112–136
These brackets match commonly used “target heart rate zone” charts for exercise and are often applied to running.

Heart Rate Zones When Running

Many runners use zones instead of one fixed number.

  • Zone 1 (very easy): about 50–60% of max; gentle jog or warm-up.
  • Zone 2 (easy): about 60–70%; conversational pace for building endurance.
  • Zone 3 (moderate): about 70–80%; “comfortably hard” steady running.
  • Zone 4 (hard): about 80–90%; tempo runs, short race pace.
  • Zone 5 (very hard): 90–100%; sprints and very short intervals, not for long durations.

Many coaches recommend most weekly mileage in easier zones (1–2), especially for newer runners, with limited time in the higher zones.

How To Tell If Your Heart Rate Is OK

Even with smartwatches, how you feel still matters.

  • If you can talk in short sentences, you’re probably in a moderate zone.
  • If you can only get out a few words, you’re likely in a hard/vigorous zone.
  • If you feel chest pain, dizziness, or unusual shortness of breath, stop and seek medical help, especially if this is new for you.

People with heart disease, on certain medications, or with symptoms need personalized limits from a healthcare professional.

Key Safety Notes

  • “Normal” varies with age, fitness, medications (like beta-blockers), heat, dehydration, and stress.
  • New runners often run too fast and see very high heart rates; slowing down and using walk breaks can keep heart rate in a safer, more sustainable range.
  • For a truly accurate maximum heart rate and safe training zones, a supervised exercise test is the gold standard.

TL;DR: Aim for roughly 50–70% of your estimated max heart rate for easy–moderate runs and 70–85% for harder sessions if you are healthy, and get personalized advice if you have any medical concerns.
