Running is one of the most effective aerobic activities for improving cardiovascular health and overall well-being. Yet understanding how heart rate changes during training remains a challenge for many runners, especially in the first few months. Here are 7 concrete strategies to lower your heart rate at a given pace — and ultimately run faster with less effort.
Heart Rate While Running
Heart rate refers to the number of times your heart beats per minute to circulate blood through the body. During exercise, this rate naturally increases, as the heart must pump a greater volume of blood to the muscles. It is essential, especially for athletes, to know your resting heart rate and your maximum heart rate — two key indicators of fitness and general health. Maximum heart rate in particular plays a central role in training planning.
It is worth emphasizing that heart rate is a highly individual value: comparing yourself to other athletes is not meaningful. For reliable data, a maximal exercise test is the best option. It is also possible to estimate maximum heart rate using formulas or hill sprints, but the results remain approximate.
Many athletes train by heart rate. This approach allows for precise training management and a better sense of the body. A common goal is to reduce heart rate at a given speed, which lowers perceived effort and optimises athletic performance.
Below, we present 7 strategies to lower your heart rate.
1. Be Consistent and Progressive
It is no coincidence that marathon runners achieve a resting heart rate of 40 to 50 beats per minute: regular, targeted training is the key to lowering heart rate. The fitter you are, the slower your heart beats at the same effort level. Avoid starting too fast or increasing the load too abruptly: begin each session at a moderate intensity and progress gradually. This gives the heart and muscles time to adapt and reduces cardiovascular stress.
During the run itself, avoid sudden pace changes — unless it is an interval session. Maintaining a steady, even pace allows the body to regulate heart rate far more efficiently.
2. Vary Your Training Types
LONG RUNS
Long-duration training is essential for stimulating cardio-circulatory adaptations. It allows the heart to get used to sustaining prolonged effort without intensity spikes. As a result, the average heart rate during exercise decreases, since long runs increase both cardiac volume and capacity. Beginners can easily alternate between running and walking.
LOW-INTENSITY SESSIONS
Running slowly is often underestimated, but its effects on cardiovascular efficiency and fat metabolism are significant. To get the most out of it, aim for an intensity between 60 and 75% of your maximum heart rate.
HIGH-INTENSITY SESSIONS
It may seem counterintuitive, but intense training — intervals and threshold runs — also contributes to lowering heart rate. By exposing the heart to greater demands, it learns to adapt and gradually becomes capable of sustaining higher intensities. These sessions must always be introduced progressively and include adequate recovery phases.
3. Improve Your Running Technique
An efficient running technique reduces overall muscular effort and helps keep heart rate lower. Keep your back straight, shorten your stride and land your foot gently to minimise impact and improve movement economy. Pay attention to your arms as well: when they are raised above heart level for extended periods, the movement places extra demands on the body — and causes the heart rate to rise.
4. Work on Your Breathing
Correct breathing is fundamental to stabilising heart rate. Practise inhaling through the nose and exhaling through the mouth, with deep, controlled breaths. Focus on diaphragmatic breathing to improve the efficiency of your respiratory system and reduce the strain on your heart during exercise.
5. Mind Your Nutrition and Hydration
Drinking enough before, during and after exercise is essential for maintaining an optimal heart rate. Choose light, easily digestible foods around your sessions and rely on complex carbohydrates and proteins to support muscle recovery.
Consuming stimulants such as coffee, tea or chocolate before training can influence heart rhythm. Similarly, tobacco and a high-fat diet are best avoided if you want to keep your heart rate under control.
6. Try a Complementary Sport
Cross-training is an excellent way to improve cardiovascular endurance. Cycling and swimming are particularly well suited: at a comparable effort level, heart rate is slightly lower than in running, since part of the body’s weight is supported by the bike or the water. These sports allow the heart to adapt in a different way and help reduce heart rate during running sessions.
Strength training also deserves a regular place in your weekly routine: the stronger you are, the more economical your running becomes — and the lower your heart rate stays at the same pace.
7. Prioritise Sleep
We mention this last, even though it may be the most important point of all. Insufficient or poor-quality sleep raises heart rate both at rest and during exercise: the nervous system remains on alert, the heart compensates, and your training sessions suffer. Aim for 7 to 9 hours per night, with as regular a schedule as possible. Good sleep also has a direct impact on stress — another factor that keeps heart rate chronically elevated — and remains one of the most powerful tools for keeping your nervous system calm.
Conclusion
Lowering your heart rate while running takes patience, consistency and a good understanding of your body. The process is slow — it can take months or even years. A low resting heart rate is a sign of good cardiovascular health; a low heart rate at a given pace is a sign of better fitness and aerobic efficiency. In any case, every athlete is different: always take your own goals and individual characteristics into account.
