The Importance of Heart Rate Training for New Runners

If you’re new to running, you might think the key to improvement is just running hard.

But here’s the truth: running harder doesn’t always mean running better.

In fact, one of the biggest mistakes new runners make is pushing too hard too often, leading to burnout or injury.

The solution?

Heart rate training.

What is heart rate training?

Heart rate training is a method that uses your heart rate (beats per minute) to guide the intensity of your runs.

Instead of relying on pace or “how you feel,” you train within specific heart rate zones to ensure you’re working at the right intensity.

And if you are new to running, your "feel" will be laughably bad. You need to learn to feel, and HR is a great way to help you learn.

I promise, what you initially "feel" is easy will almost certainly be nowhere near truly easy.

Why it’s crucial for new runners

1. Prevents Overtraining – Many new runners go too hard, too often. Heart rate training helps you keep easy runs truly easy, allowing your body to recover and adapt.
2. Builds an Aerobic Base – Running in lower heart rate zones (Zone 1 & 2) improves endurance, making you a stronger runner over time.
3. Reduces Injury Risk – Training at the right intensity helps avoid excessive fatigue and stress on your body.
4. Improves Efficiency – By running at the right effort level, you’ll gradually become more efficient, meaning you can run faster with less effort.

Tracking your resting heart rate and heart rate variability (HRV) can also help you understand how recovered you are before your next run. I talk more about that in The Basics of HRV and RHR (And How Tracking Them Can Help).

Understanding heart rate zones

Most heart rate training methods divide effort into five zones, based on your max heart rate (MHR).

A simple way to estimate MHR is 220 minus your age, but this can be very inaccurate.

It predicts 184 for me but mine is actually 190.

And it predicts 192 for one of my clients but his is actually 203.

The best way to determine your max HR is to have it tested in a lab or to test it yourself.

Here’s a VERY basic breakdown:

Again, these are generic approximations; your actual zones could be a fair bit higher or lower.

At first, for most new runners, 70-80% of your runs should be in Zone 1-2 to build endurance and avoid burnout.

And a very good starting point for everyone is to keep all easy runs under 75% of MHR.
If you have no clue what your MHR is, I suggest starting with keeping all runs under 140bpm and see how that feels.

How to get started with heart rate training

1. Get a Heart Rate Monitor – A chest strap is the gold standard, and if you are serious about improving, I recommend you get one. Polar H10 is a great option. Smartwatches, even the most expensive ones, aren't nearly as reliable.
2. Slow Down on Easy Runs – If your heart rate is creeping too high, ease off the pace. Walk if needed. Your aerobic system improves most in lower zones.
3. Be Patient – Your fitness will improve over time. The more time you spend in lower zones, the easier and faster running will feel.
4. Use Workouts Strategically – Harder efforts (Zones 3-5) should be intentional and structured, not every run.

No matter how slow I run, my HR won't stay in Z2!

If that's the case, I have some good news and bad news.

The bad news: You are very out of shape.

The good news: You will see rapid improvement if you do it right.

If you can't run and stay in Z2, you need to walk. Or bike. Or elliptical.

Do whatever you enjoy most and spend as much time in Z1/2 as you can and you won't believe how fast you improve.

The takeaway: run smarter, not harder

Most new runners run too hard on easy days and too easy on hard days. Heart rate training fixes that.

If you want to run longer, recover faster, and improve without injury, start using your heart rate to guide your training.

Capacity Training

I built Capacity Training to plan your running and your lifting together, with heart-rate zones from your max heart rate and paces from your 5K time. If you can't run 30 minutes yet, a walk/run plan builds you up to it.
