Do Beginners Need a Heart Rate Monitor?

No — you don't need a heart rate monitor to get through a walk-run program. Running at a conversational effort — the talk test — is a more reliable guide than a heart rate zone calculated from a guessed maximum. A monitor earns its keep later, once you've got an accurate max heart rate and a reason to train by zone.

A reader named Kathryn, in Canada, working her way through Beginners Running Program 3, asked me almost exactly this — and it's one of the most common questions I get from runners just starting out.

Why "Run by Feel" Beats a Guessed Heart Rate Zone

Here's why that advice actually holds up — it isn't a shrug.

The classic formula for working out your maximum heart rate is 220 minus your age. It's popular because it's simple. It's also a population average, not a measurement of you specifically — commonly off by 10 beats per minute or more, in either direction, for any individual runner.

That matters more than it sounds. If your calculated max is wrong, every "zone" built from it is wrong too — you'd be training to a number that was never really yours. A watch telling you that 148bpm is "Zone 2" isn't giving you more precision than your own body. It just feels like it is.

The talk test skips the guesswork entirely. Run at a pace where you can hold a proper conversation — string full sentences together, not just gasp out single words — and you're training at genuine aerobic effort, full stop. No formula, no watch, no guessed number required.

That's the real reason "run by feel" isn't a shrug. It's the more accurate method, not the fallback one.

When It's Worth Adding a Heart Rate Monitor

A heart rate monitor isn't useless. It just isn't the beginner tool it's often marketed as.

Once you've worked through a structured walk-run programme and you're running continuously — no more alternating walk and run intervals — a monitor starts earning its place. At that point it's genuinely useful for two things: keeping your easy days honestly easy, and confirming your hard days are actually hard.

Before you set any zones from it, get a proper reading on your max heart rate — a field test or a lab test — rather than leaning on the age formula. Get an accurate max heart rate reading first, then build your zones from that real number. Zones built on a guess are still a guess, however good the watch is.

Is It Normal for a Run-Walk Session to Feel Hard?

Yes — and one tough session doesn't mean anything's wrong.

Some days a run feels comfortable start to finish. Other days, the exact same prescribed effort feels like a real push. Sleep, fuelling, stress, and how recovered you are all move the needle — that's normal, not a sign your programme is wrong for you.

One bad session isn't a red flag. A whole week where every single run feels unusually hard is — that's your cue to repeat the week, or step back one stage, rather than grinding through it.

Not every heart-rate concern is about needing a monitor in the first place. If you're worried your heart rate reads too high instead?, I cover that separately.

Frequently Asked Questions

Do I need a heart rate monitor when I first start running?
No — use the talk test instead: if you can hold a full conversation, you're at the right effort. A monitor becomes genuinely useful once you've got an accurate max heart rate and a reason to train by zone.

What heart rate zone should a beginner run in?
You're better off running by effort — conversational pace — than by a zone calculated from a guessed max heart rate, which is commonly off by 10 beats per minute or more.

Is it normal for a beginner running program to feel challenging?
Yes. Some sessions feel harder than others because of sleep, fuelling, and stress. Only a whole tough week is a signal to repeat it or step back a stage.

Can you run barefoot with high arches?
A high, rigid arch absorbs less shock naturally, which works against you as a barefoot candidate. A gradual transition toward an efficient midfoot strike in a moderately cushioned shoe is the safer route — going straight to barefoot or minimalist footwear is where most transition injuries happen.
