Distance runners can use a heart rate monitor to effectively train for long-distance races. In this post, I’ll give you the best reasons why you should start training with a heart rate monitor. To begin, you’ll need two very important items to assist you in this journey:
- A heart rate monitor you can trust. While new Garmin watches, like my 235, have a sensor on the underside of their watches, I strongly suggest purchasing a chest strap for a more accurate read. Can you train just using the watch’s heart rate function? Sure. But your heart rate is probably best measured closest to your heart.
- A verified test to determine your maximum heart rate. This test is usually performed on a treadmill, but may also be done on a track. Back in college, I was tested and my max heart rate was 198. Heart rate is totally individualized – my heart rate has NOTHING to do with what yours might be. My friends at System Based Training can do this for you if it’s something you are interested in.
Why do you need a heart rate monitor and why is your maximum heart rate important? Simple: the heart rate monitor tracks what your heart is doing and knowing your max heart rate allows you to train within heart rate zones.
Again, this should go without saying, but you cannot accurately train using your heart rate without knowing your maximum heart rate and then using appropriate training zones to train for your desired running event.
Here’s a quick list of what you need to remember before you start training via heart rate:
- The biggest myth is determining your maximum heart rate by subtracting your age from 220.
- Your training paces will increase based on your fitness level
- Every run you do is based on effort – the effort of your heart. So if you are fatigued, your heart rate will let you know and you’ll run slower on that day.
- You train at speeds/paces that your heart rate tells you you can train at. An easy run suggests you train at 65-79% of your maximum heart rate. Your pace might fluctuate 30 seconds to a minute per mile. If you are tired, your heart rate will be higher and your pace will be slower.
- You can cheat your heart rate [run faster than your HR suggests], but you’ll pay for it eventually.
The 6 Benefits to Heart Rate Training
Your Training Paces
Your training paces will be set/determined for you based on your current fitness and the “strength” of your heart. If you are in shape, your heart will function more optimally – meaning it will require fewer beats to pump more oxygen-rich blood through your body. Out of shape? Your heart will require more beats to pump that same oxygen-rich blood.
As you get in better shape (day by day of running in your correct zones), your easy running pace will get faster. If your easy runs were at a 9-minute pace with a heart rate of 150, for example, after consistent training, your pace will improve while your heart rate will stay at 150.
Find (and stay in) Training Zones
When you first begin training based on your heart rate, there’s the likelihood that you look at what your pace is and running based on that information.
With heart rate training, you look what your heart rate is telling you and you run based on that information. The fitter you get, the stronger your heart will get and the less work it will require to pump oxygen and blood through your body.
The actual training using a heart rate monitor is the same. You’d still be prescribed a tempo run or 400 repeats. Using a heart rate monitor, the fastest you can/should go is determined by your heart. If your HR says you are at the upper limit of your tempo zone, that’s as fast as you can go – regardless of what the pace is. Remember that outside factors play a role in your heart rate [weather, terrain, elevation, sleep & diet for example].
A tempo run done at 3,000 feet of elevation, temps in the 80s with high humidity will present a higher heart rate (and therefore a slower pace), while under different conditions, a similar tempo run at 100 feet of elevation, temperatures in the 50s with no humidity will require much less work/effort for your heart rate and therefore you’ll be able to run much faster.
Staying in your heart rate zone will ensure you are training at the appropriate effort level and pace. Regardless of what your pace says, you train based on your heart rate and the respective zones.
Guess Work is Gone
That’s right – the guesswork is gone. You no longer need to know what pace you should run. Your main goal is to get your heart rate into its right zone and stay there for as long as you can. Running repeat miles? Awesome. Get your heart rate up into the zone it’s supposed to be in and keep it there.
Will your first mile be easier than your last? Yes.
Will your paces stay the same? Maybe not.
This is because as you tire, your body will require more energy to do the same amount of work. This will put more strain on your heart, which will make it beat more. BUT – this is how you get stronger and fitter! As long as you are staying in the zone you’re supposed to be in, this will boost your performance.
Your heart is a very sensitive organ. It knows and can detect when you are tired. It will show up in the form of higher beats per minute. Similarly, a bad diet (long term, but also short term) will keep your heart rate beating at a slightly faster rate. Both of these factors are things that YOU can control.
What you can’t control are factors like weather (extreme heat, humidity, extreme cold), elevation, and terrain (hills, grass, trails). Training in less-than-ideal conditions shouldn’t be eliminated, they should be accounted for. When all factors are made equal, the racing performances will be there.
Training for a distance race using a heart rate monitor can be very beneficial to runners who are seeking an alternative to the traditional run-by-pace training typically laid out by most coaches. Heart rate training is very effective at determining the appropriate paces that runners can/must train at to improve running (and racing) performances.

There are, of course, outside factors that play a roll in your heart rate, but once those are accounted for, training is very much the same as “traditional” running. For example, instead of running repeats at an 8-minute pace, you might be given run 5 x 800 @ threshold. The difference becomes instead of running based on the pace, you run based off of your current/real-time heart rate and the appropriate zone you’re supposed to be in for threshold workouts.
As you get in better shape, your resting heart rate will be lower and your heart will require less energy to pump blood through your body at every given speed. What used to take 175 beats per minute to run at a 7-minute pace, now only requires 170 beats for the same pace. Training based on heart rate allows you to run a smidge faster to keep at your same 175 beats per minute! Your heart has demonstrated that you can do more work and you are ultimately a faster runner – getting more bang for your buck.
