How to avoid the most common Zone 2 running mistakes
If you're new to heart rate run training, this guide will help you avoid common mistakes and make it easier to start. Taren Gesell explains…
This guide will help you avoid the five most common mistakes beginners make when running in Zone 2. If you’re new to heart-rate running in your training plan, you’ll know that it can initially be hard to get into the swing of things.
We lay out the five mistakes most people make when running in Zone 2. Knowing about these mistakes and how to avoid them can set you up for success as you start your journey with zone-based heart-rate run training.
If you’re new to Zone 2 running, then it might help you to read our Beginner’s guide to Zone 2 running as a starting point.
Mistake #1: Using a wrist-based heart-rate monitor
People often make the mistake of using wrist-based heart-rate monitors (like the ones you find on triathlon watches) to track their heart rate while they work out. Even though these monitors are easy to use, cheap and convenient, they tend to be less accurate than chest-based heart rate straps.
The problem with wrist-based monitors is that they use sensors that measure blood flow through the wrist, which is often inaccurate, especially when the wrist is moving around a lot or the body is sweaty during high-intensity exercise (here’s the research).
Heart-rate monitors worn on the wrist can sometimes give readings that are off by as much as 40 to 50 beats per minute. That’s a margin of error big enough to render them unreliable at best, ineffective at worst.
On the other hand, chest-based heart-rate straps use sensors that pick up the heart’s electrical activity; this is a better way to measure heart rate because it doesn’t change when you move or sweat. Some people find chest-based heart-rate monitors uncomfortable. If this is the case, you can use an armband heart-rate monitor, which is also typically very accurate.
Mistake #2: Not setting up the correct heart-rate training zones

Heart rate training zones are ranges of heart rates used to work on different energy systems and reach different fitness goals. For example, zones one and two are primarily for endurance training or warm-ups, while zones four and five are for high-intensity interval training, which helps you get faster.
People often make another mistake when running in Zone 2: not setting their training zones properly. Setting up your training zones correctly is important because it ensures you’re working out at the right level of intensity for your fitness goals. If your heart zones are set too low, you won’t be able to run in Zone 2 for very long.
The Karvonen Method is the best way to determine your training zones. This method looks at your resting heart rate (RHR) and maximum heart rate (MHR). Your MHR can be calculated with a max heart rate test or using the formula 220 minus your age, but is better calculated these days using a heart rate monitor and going flat-out during exercise.
The Karvonen Method is useful because it considers your unique body to give you a set of heart rate training zones that are just right for you.
To use the Karvonen method, you need to know your resting heart rate (RHR) and maximum heart rate (MHR). Then, to figure out your Zone 2 training zone, you can use the following formula:
- Lower range = ((maximum heart rate – resting heart rate) x 0.6) + resting heart rate
- Upper range = ((maximum heart rate – resting heart rate) x 0.7) + resting heart rate
For example, if an athlete’s maximum heart rate is 190 and their resting heart rate is 60, and they want to work at an intensity level of 60-70% (the Zone 2 training zone), their training zone would be:
- ((190 – 60) x 0.6) + 60 = 138 beats per minute ((190 – 60) x 0.7) + 60 = 151 beats per minute)
This means that for their Zone 2 heart rate running, this athlete should try to keep their heart rate between 138 and 151.
If you want to know what your heart rate is in Zones 1, 2, 3, 4, and 5, you can use this calculator to avoid the mental arithmetic.
To get the most out of your workouts, you must set your heart-rate training zones correctly. Based on your resting heart rate and maximum heart rate, the Karvonen method is a simple and accurate way to figure out your zones.
Here’s where you can find the best heart rate zones for running.
Mistake #3: Running on hills or when it’s hot

Many runners also make the mistake of not thinking about how running up hills and heat can affect their heart rate. It’s important to be aware of these things because they can make your heart rate go up a lot and make it harder for you to stay in Zone 2.
When you run up a hill, your heart rate will naturally go up because you must work harder against more resistance. This is especially important on steep hills, where the additional effort required to get up the hill can be significant. So, even if you are running at a low-intensity level, keeping your heart rate low while running uphill can be hard.
In the same way, running in hot weather can also make your heart beat faster. When you work out in hot weather, your body has to work harder to cool itself down, which can raise your heart rate. This is especially important if you’re running in humid weather because the extra moisture in the air can make it harder for your body to get rid of heat.
To deal with these problems, you need to keep your ego in check when running uphill or in hot weather, and you may need to slow down a lot to keep your heart rate in Zone 2.
Here’s where you can find out more about why your heart rate is so high on easy runs if that’s an area of concern.
You may also need to try to do your Zone 2 runs at a low intensity on flat ground or, if you live in a hot country, early in the morning before it gets too hot. Also, staying hydrated and taking breaks to walk around as needed is important to let your heart rate recover.
Mistake #4: Thinking that you have to run during all low heart-rate runs

Many runners think they must run the whole time when their heart rate is low. Even though running should be a big part of your training plan, there are other ways to get a low heart-rate workout that can be just as good.
Turning your long runs into long hikes in Zone 2 is another way to train. Instead of running at a slow pace, which most people find boring, you could hike slower, keeping your heart rate in your Zone 2 range. Hiking can be a great way to change up your training and give your joints a break from the impact of running.
There are many good things about hiking in Zone 2. First, it lets you work on your endurance without putting as much strain on your body as running does. This can be helpful if you are recovering from an injury or just want to train in a way that doesn’t hurt as much.
Zone 2 hiking is also a great way to find new trails and enjoy the great outdoors. Hiking will also reduce your likelihood of developing a running injury.
Also, consider hitting the trails for multiple benefits, as here’s how off-road running can improve your triathlon run performance as well.
Mixing up how you train can also help keep things interesting. Adding hiking to your training plan can keep your workouts from getting boring and make yourself a more well-rounded athlete.
Mistake #5: Thinking you’ll make running improvements quickly

A common mistake that many athletes make is to think that their training will make them better quickly. Even though it is possible to see some initial performance improvements after a few weeks of consistent training, it is important to be realistic about how long it will take to see more significant changes.
When it comes to Zone 2 running or endurance training, it’s important to remember that progress is often slow at first. It can take as long as four or five months to see a big improvement in performance from Zone 2 running.
Training for endurance takes a long time and requires consistent effort over time. Running in Zone 2 has benefits beyond just improving performance immediately.
With low-intensity endurance training, you can keep improving yearly instead of plateuing, which can happen with other, more intense types of training.
Zone 2 training also has long-term health benefits, such as lowering the risk of heart disease and diabetes.
Hopefully this guide has given you the tools to avoid these common training mistakes and reach your goals. As you work towards them, remember to always listen to your body, stay consistent and be patient.
