How to Control Your Heart Rate While Running

If your smartwatch is flashing a high number or you feel your heart pounding mid-run, you might wonder. Is my heart rate too high and how can I bring it down?

Knowing how to lower your heart rate while running can help you stay safe, run longer, and build endurance. Whether you’re just getting started or increasing your training intensity, learning to stay within your ideal heart rate range is a smart part of any runner’s routine.

Why Your Heart Rate Rises During Running

Your resting heart rate usually falls between 60 and 100 beats per minute (bpm). When you run, your heart rate increases to supply oxygen-rich blood to your working muscles. Depending on your age, your maximum heart rate likely ranges from 150 to 200 bpm.

While temporary heart rate increases are a normal and healthy part of exercise, consistently exceeding your max heart rate may raise health risks especially if you have cardiovascular issues. That’s why it’s important to recognize your limits and learn techniques to lower your heart rate when needed.

7 Effective Ways to Lower Your Heart Rate While Running

1. Practice Deep, Rhythmic Breathing

Your heart and lungs are tightly linked. Slowing your breath can activate your parasympathetic nervous system, which helps your heart rate come down.

• Inhale through your nose and exhale through your mouth.

• Aim for a steady rhythm counting to four on the inhale and exhale may help.

• Practice during warm-ups so it becomes second nature on the move.

2. Hydrate Well Before, During, and After

Dehydration causes your heart to work harder, raising your heart rate. Runners lose water and electrolytes, especially in warm conditions.

• Drink water throughout the day not just during your run.

• Add electrolytes if you’re running longer than 45 minutes or in heat.

• Avoid starting a run thirsty; pre-hydration helps keep your heart rate stable.

3. Slow Down Your Pace

The harder you push, the faster your heart beats. If your heart rate climbs too high, ease into a slower pace or walk until it stabilizes.

• Try interval training: alternate fast and slow segments to build endurance safely.

• Use the “talk test” if you can’t speak a full sentence, you may need to slow down.

4. Train Consistently to Build Cardiovascular Fitness

As your fitness improves, your heart becomes stronger and more efficient, meaning it doesn’t have to work as hard.

• Over time, your resting and exercise heart rates decrease.

• Stick to a consistent training schedule 3 to 5 days a week is a good start.

• Be patient; noticeable changes may take several weeks to months.

5. Avoid Stimulants Before Running

Caffeine and pre-workout supplements can artificially increase your heart rate which may lead to early fatigue or discomfort.

• If you're sensitive to stimulants, skip coffee or pre-workout before your runs.

• Read supplement labels and avoid products with high caffeine content.

6. Manage Stress and Anxiety

Emotions like stress, frustration, or anxiety can elevate your heart rate. Use calming techniques to stay grounded:

• Try a quick breathing meditation before your run.

• Listen to calming music during your warm-up.

• Practice mindfulness or walking meditations on low-intensity days.

7. Incorporate Strength Training Into Your Routine

Resistance training builds muscular strength and cardiovascular efficiency, both of which contribute to a lower heart rate during cardio workouts.

• Add 2 sessions of weight training per week.

• Focus on compound movements like squats, lunges, or deadlifts.

• Complement your running schedule without overtraining.

Understanding Target and Maximum Heart Rates

Your maximum heart rate (MHR) is estimated using the formula:
220 – your age = max heart rate

From there, your target heart rate zone is:

• 50–85% of your MHR, depending on your fitness goals.

Example: If you're 35 years old, your max heart rate is approximately 185 bpm. Your target zone would be about 93–157 bpm.

Staying in this range helps improve endurance without overstraining your heart. If your heart rate goes above this range regularly, it may be time to dial things back.

Factors That Can Affect Your Heart Rate While Running

Your heart rate isn’t just about speed or effort. It can also be influenced by:

• Age: Heart rate typically decreases with age.

• Medication: Beta-blockers and other prescriptions can blunt heart rate response.

• Weather: Heat and humidity can increase cardiovascular strain.

• Hydration: Even mild dehydration increases heart rate.

• Stress and emotions: Anxiety can raise your heart rate before you even start moving.

• Fitness level: Newer runners often see higher heart rates during easy runs.

Is It Dangerous to Exceed Your Max Heart Rate?

Occasional spikes above your max heart rate during intense exercise are usually not harmful in healthy individuals. However, regularly exceeding it may increase the risk of:

• Heart palpitations

• Irregular heart rhythms

• Fatigue or dizziness

• Increased risk of cardiovascular events, especially in those with pre-existing conditions

Your recovery rate how quickly your heart rate returns to normal after exercise is a good indicator of cardiovascular fitness. A slower recovery may suggest overexertion or health issues.

When to Seek Medical Advice

Contact a healthcare provider if you experience any of the following during or after running:

• Shortness of breath beyond normal exertion

• Persistent rapid heartbeat at low intensity

• Dizziness, fainting, or chest discomfort

• Palpitations or an irregular heartbeat

Always check with your doctor before starting or significantly changing an exercise routine especially if you have heart-related conditions.
