The best heart rate monitor for running should be comfortable to wear, accurate, and affordable. It should allow you to move freely. It should also be easy to read without slowing you down too much. There are a ton of heart rate monitors out there, but they typically fall into 2 styles: chest strap or watch.
Each have their own benefits, but it’s really up to you to consider which features are most important. This guide will discuss the differences between the different types of mon
itors, educate you on the available features, and give you a list of the best heart rate monitors on the market.
What Is A Heart Rate Monitor?
First things first, a heart rate monitor is a piece of equipment that measures your heart rate. Your heart rate (HR) is defined as the number of times your heart beats in one minute. According to the Mayo Clinic, most healthy adults have a resting heart rate of 60-100 beats per min (bpm). Now this is the RESTING heart rate. When we move or exercise, this rate increases because our heart needs to send more blood throughout the body to supply the working muscles.
Why should we be concerned with our heart rate while we exercise? Well, it’s a great indicator of how hard you are working. Knowing your heart rate allows you to exercise at an intensity difficult enough to get the desired benefits you are looking for. According to the American Heart Association, we should be exercising at 50-85% of our max heart rate.
There are a lot of different equations to determine your own max heart rate. An easy one I learned a long time ago that still seems to work pretty well is to subtract your age from 220. I’m 35, so 220 – 35 = 185. My estimated max heart rate would be 185 bpm.
While I’m exercising, my goal should be somewhere between 50-85% of 185: or 93-157 bpm. If you like math, feel free to find your own target heart rate zone. If not, here is a nice resource for finding your own target HR zone.
You may be thinking 50-85% is a really big range. I agree. A lot of folks break it down a little more specifically depending on what kind of results you are looking for. 50% of max heart rate would be more for a beginner or for warming up. 60-70% would be more for a “fat burning” workout- this old train of thought may be out dated, but the old thinking was that working out at a moderate pace for prolonged periods burned more fat.
Well, the way I look at it, the more intensely you exercise, the more calories you are going to burn, and ultimately the more fat you will lose…ie, the recent popularity of the HIIT workouts.
But, if you are doing a fat burning HR workout on a treadmill or elliptical, they are probably using the 60-70% definition. Working out in the 70-85% range would be more intense exercise, or in the “cardio” range. This intensity is where you are going to get the most benefit for your heart and cardiovascular system. Definitely going to burn more calories with this type of activity.
This is why heart rate monitors have become so popular. It gives the user an easy way to measure their heart rate, which in turns measures the intensity at which they are exercising. They can ensure you are working hard enough to burn that fat and improve your cardiovascular health.
Types Of Heart Rate Monitors
I mentioned briefly above that there are 3 different types of heart rate monitor: chest strap, touch watch, and continuous-reading watch. Let’s take a closer look at each so you can determine which type will work best for you while you run.
Chest Strap Heart Rate Monitor
These HR monitors use a strap that fits snuggly across your chest to measure your heart rate. These devices have a sensor on the underside of them (the side against your skin) to detect the electrical activity of your heart. Very similar to the devices your MD uses to check your heart during an EKG.
This signal is sent to a transmitter, usually in the form of a wrist watch, where the reading will be displayed. In order for a chest strap HR monitor to work, you have to wear the strap and the watch at the same time. Some chest strap monitors can also be connected to smart phones through bluetooth.
Benefits of chest strap monitors:
- Provide continuous HR readings
- More accurate readings
- Allow you to move freely while you run or exercise
Disadvantages of chest strap monitors:
- Have to keep the sensor wet (usually isn’t an issue once you start sweating)
- Can be uncomfortable to wear
Touch Watch Monitors
These devices measure your heart rate directly from your wrist. These are also known as optical heart rate monitors. They use light to measure blood flow and determine heart rate. The “touch” part comes from the fact that you have to touch the screen to see your heart rate.
Optical HR monitors have gotten a lot nicer and a lot more accurate in the last few years. That said, chest strap monitors are still considered to be the most accurate because they are much closer to the heart and are directly measuring the electrical signal from the source.
Benefits of a touch watch monitor:
- Don’t have to wear a chest strap
- Convenient and easy to use
Disadvantages of a touch watch monitor:
- You have to touch a screen/button to see HR- this can be difficult during running
- Sometimes there is a small delay
- Not as accurate as chest strap
Continuous-Reading Watch Monitors
These models are identical to the touch watch monitors, however you do not have to touch a button to see your results. Your heart rate is continuously being analyzed while you run. These monitors are also worn like a watch. There is no chest strap involved.
These machines are a little newer and tend to cost a little more. The accuracy of these optical HR monitors continue to improve. Sometimes movement of the monitor can take away from the accuracy of the reading, but as long as you have the watch snug on your wrist, it shouldn’t be much of an issue.
Benefits of a continuous-read monitor:
- No need to touch button/screen to see HR
- Easier to use while running
Disadvantages of a continuous-read monitor:
- More expensive
- Still not as accurate as chest strap
Other Features To Consider
There’s more to consider that just between a chest strap or wrist HR monitor. There’s also all the other available features that HR monitors can do. A lot of smart watches now have the ability to monitor HR, so if you get one of these monitors you will have the ability to do all kinds of functions a typical HR monitor can’t do. Some additional features offered include:
Some monitors give you the ability to preprogram different styles of workout based on the heart rate: cardio, strength, run, walk, etc. The number of zones available depends on the device, many offer 3-6 different training zones.
This feature estimates how many calories you burn while you exercise. This is an awesome feature if you are trying to lose weight. These devices make an educated guess based on your HR readings.
GPS capability allows you to track speed, distance, and even map out your route. This feature can even be used to measure elevation if you like to hike or trail run. This is a great feature for runners. It’s also really helpful if you like to explore and run new routes- the GPS functions are many monitors will make sure you find your way back home.
Recovery HR Mode
This mode records the amount of time it takes your HR to return to it’s resting level after you finish exercising. This is another good indicator of fitness. The shorter the time, the more fit you are.
A lot of HR monitors these days can connect to your tablet or smart phone via bluetooth. This allows you to record your workout stats easily and chart your progress. Many monitors are compatible with multiple workout apps.
Some devices will alert you if you fall out of your target zone. They act as your very own personal trainer while you run to keep you working hard enough to keep your heart rate in the zone. Some also have visual aides, like colored lights or messages to keep you motivated.
Activity trackers monitor your movement throughout the day. This includes keeping track of your steps taken, active times, rest times, and sleep. They can also be set to different sport modes to more accurately track data while you cycle, row, hike, etc. Fitbit is a very popular manufacturer of activity trackers. Many high end HR monitors also provide activity tracking.
These are just a small sample of some of the available features on HR monitors these days. With all of the new technology coming out, the available features will continue to improve. It’s important to consider what features are important to you. There is no need to pay more for a bunch of fancy features you aren’t going to use!
The Best Heart Rate Monitors For Running
Chest Strap Heart Rate Monitors
#1 Polar FT7 Heart Rate Monitor
The Polar FT7 is one of the highest rated chest strap monitors you can find. Users love it for it’s accuracy and it’s comfort. As a chest strap monitor, it’s able to provide pin-point accuracy continuously as you run. Remember, these monitors are tracking the electrical activity of your heart to calculate you rate.
The Polar FT7 includes both the chest strap and the watch monitor. No need for you to buy anything separately. A nice thing about the chest strap is that it is made out of a soft fabric. Some chest straps are made of tough rubber which can be uncomfortable as you run. This soft fabric strap will easily conform to your body and move with you without pinching or chaffing.
This device can also keep track of how many calories you burn as you run. It estimates calories burned based on your heart rate during exercise.
Another feature you will enjoy is the “energy pointer”. This feature tells you how much time you are spending in the “fat-burning” zone and the “fitness improvement” zone during your workout. This will come in handy if you are running to try and lose some extra pounds.
Here are some additional features I think you will enjoy:
- Easy to read display on watch- makes it easier to check your HR during your run, no need to stop
- Chest strap is comfortable and breathes well- you may forget you are wearing it
- This monitor links with compatible gym equipment, so you can see your HR on the monitor of the machine
- Polar has their own fitness app for tracking stats
- Uses Bluetooth to communicate with smart devices
- Affordable price
Overall, the Polar FT7 has become one of the most popular HR monitors for it’s price and easy to use, accurate measurements. This monitor would be great for running because of how comfortable the fabric chest strap is.

#2 Wahoo TICKR Heart Rate Monitor
The Wahoo TICKR takes a slightly different approach to heart rate monitoring. You buy the chest strap and it connects with your smart device to display your heart rate. This monitor is compatible with pretty much every smart phone/tablet/fitness app you’ve ever heard of, so compatibility shouldn’t be a problem. Just know that to use this chest strap, you will need to use some type of smart device to access your data.
The TICKR uses bluetooth and ANT+ to communicate with different devices. If you aren’t familiar with ANT+, it’s basically just another form of wireless communication technology that a lot of exercise monitors use. Click here for more info. But the takeaway here is that this chest strap uses BOTH technologies- this means it is compatible with iPhones, Androids, GPS watches, and cardio machines.
This monitor will also calculate calories burned and determine your training zones when paired up with a compatible fitness app.
This heart rate monitor would be great to track your running stats because the strap is elastic and adjustable, one size fits all. With this comfortable strap you won’t have to worry about irritating your skin while you run.
The TICKR is the HR monitor of choice for the defending champions of the Tour de France, that’s pretty cool.
This device works very well for calculating HR and is super compatible, but if you are interested in more advanced running analytics (i.e. cadence, vertical oscillation, etc) you may want to check out the TICKR Run.
This is a great device if you are currently (or willing to start) using a smart phone or smart watch device. If you are not interested in using a fitness app to record your stats, this is not the HR monitor for you! The Wahoo TICKR needs to be paired up with a smart device so you can see and record your heart rate.

#3 Polar FT60 Heart Rate Monitor
With the FT60, Polar added a few more features to turn this HR monitor into more of a personal trainer. I’m more fond of the the monitors that have a watch display as opposed to the smart devices- I don’t know, anytime I can get rid of the phone for a while I think it’s a good thing. So I really like that the FT60 can track so many stats and offer fitness data from a wrist interface.
The FT60 tracks HR of course, as well as calories burned and fat burn percentage. This will come in very handy if you are exercising with the goal of weight loss. This monitor will really help you stay inside that “fat burn” zone during your run to ensure you are burning as much fat as possible during your workout.
This monitor also has a built-in fitness test to help you track your progress over time. You perform a 5-minute fitness test and the device can measure how long it takes your HR to return to baseline. As you become more fit, your time should be faster.
The Polar FT60 also has a STAR training feature that creates weekly workout plans for you. It sets time, calorie, and intensity goals for you to meet during your workouts. As you meet them, it adjusts to make them progressively harder. You could have your own personal trainer encouraging you to work harder right there on your wrist.
Some additional features the FT60 can provide include:
- Comfortable, fabric chest strap that won’t pinch
- Compatible with most gym equipment- makes it easy to track heart rate while running on a treadmill
- Has backlight to improve disability if running early in the morning or at night
This is a great monitor if you are looking for a few more features in your device. The training programs can be helpful if you need a little encouragement during your workouts. With an average rating of 4.0/5, the Polar FT60 is one of the most popular heart rate monitors on the market.

#4 Garmin HRM-Run Heart Rate Monitor
Garmin, like Polar, produces several different HR monitors, but this one is designed specifically with runners in mind (as the name implies). This HR monitor is a great choice for serious runners that are looking to improve their form. If you are a casual runner just looking for a HR monitor, this device may give you a little more info than you need. That said, it will still deliver exceptionally accurate HR results.
Along with measuring your HR, the HRM-Run will also analyze your cadence, vertical oscillation, ground contact time, ground contact time balance, stride length, and vertical ratio. I’m not going to pretend to know what all of that means, but as you can see, this device is sophisticated enough to sense several different aspects of your running pattern.
For serious runners, this can help you improve your running mechanics in a few different ways. This monitor may be able to help you adjust your pattern enough to make you a more efficient runner. If you are spending too much time in the air (away from the ground), you may be expending too much energy that could be used more effectively if you take some of the “spring” out of your run.
Stride length is another key quality this device can help you adjust. Increasing or decreasing your stride length can definitely effect your speed and energy expenditure.
Most folks that use the Garmin HRM-Run appreciate how comfortable the chest strap is. There are few complaints about comfort or skin irritation. Again, this device is designed specifically with running in mind. Garmin was wise enough to include a comfortable strap.
This device uses ANT+ to communicate with other Garmin devices. You will need a watch interface to see the HR stats in real time. Amazon offers several affordable bundles that include the HRM-Run.
If you are a serious runner looking to improve your form, this could be the perfect HR monitor for you.

#5 Timex Unisex T5K730 Easy Trainer Analog HRM
I’ve always been a fan of Timex sports watches- dependable, affordable, easy to use. The same could be said about their HR monitor here. It doesn’t offer a lot of fancy metrics or features, but it does provide a very affordable HR monitor that will give you an accurate reading while you run.
This chest strap, like all, needs to be kept moist in order to ensure an accurate reading. You can use a little aloe vera at the beginning of your workout and that should work well. As you start sweating, it will stay wet and continue to provide good HR readings.
This HR monitor is nice for running because the display is large enough to see as you move. No need to lose momentum during your workout by stopping to check your HR.
Being Timex, of course they included a watch. But that’s really the only other feature this device includes. Like I said, it’s as simple as they come, but if you are only looking for a HR monitor that does just that (tracks HR), you may not have the need for a bunch of other additional features. You can save yourself plenty of money by skipping the advanced options.
Overall, this is a decent, simple HR monitor that isn’t going to break the bank. This would be a good HR monitor for beginners or recreational runners who are not looking for any advanced capabilities from their device.

Fitbit has been in the activity tracking game for a while. With the Charge 2, they have developed a pretty sophisticated HR monitor as well. The Charge 2 will track all of your steps during the day as well as give you a continuous reading of your resting HR. Set it to run mode, and you can easily track your pace and distance through connected GPS with your smart phone.
The Charge 2 is very small and light weight. The screen is small, so if you are looking for a large display you should probably consider another monitor.
The continuous HR monitoring makes it great for comparing resting HR to your active HR during exercise. This will also give you a much more accurate estimation of calories burned. The Charge 2 also gives you simplified HR zones during exercise: fat burn, cardio, and peak. This makes it easy to know which zone you are in while you workout and lets you know if you have to step up the intensity to get your desired results.
This tracker also measures sleep patterns based on heart rate. This device will even tell you to relax and breath deeply during the day if your heart rate starts to rise (indicating stress). That’s a nice feature, most of us aren’t breathing deep enough as is.
Overall, the Fitbit Charge 2 is a wonderful HR monitor as well as activity tracker. This device gives you more features than a standard HR monitor, but doesn’t cost as much as a more advanced smart watch. This is also the most popular HR monitor on Amazon- it’s boasting an average rating of 4.2/5 with over 14,000 reviews! Click here to read the full review on the Fitbit Charge 2.
