Why Your Easy Runs Are Too Fast — And How to Fix It

By Coach Nic Baxter | NBx Running Coach

I'm going to say something that might sound ridiculous......your easy runs are probably too fast.

I know — you don't feel like you're pushing. It feels comfortable. It feels like you're barely trying. But if you can't hold a full, flowing conversation without pausing to catch your breath, you are not running easy. And it's costing you more than you realise.

This is one of the most common mistakes I see in runners of all levels — and fixing it is one of the single most impactful changes you can make to your training.

WHAT IS AN EASY RUN SUPPOSED TO FEEL LIKE?

Truly easy running should feel almost embarrassingly slow. We're talking fully conversational — able to chat in complete sentences, not just single words between gasps. If you're running alone, you should be able to recite the words to your favourite song without struggling for breath.

In heart rate terms, easy effort typically falls in Zone 1-2 — roughly 60-70% of your maximum heart rate. For most recreational runners this translates to a pace that feels frustratingly gentle compared to what they're used to.

And that discomfort — that feeling of surely this is too slow to be doing anything? — is exactly why so many runners speed up.

WHY DOES IT MATTER SO MUCH?

Here's what's actually happening in your body during an easy run. You are building your aerobic base — the physiological foundation that underpins every other aspect of your running performance.

Easy running stimulates the development of mitochondria — the energy-producing cells in your muscles. It increases the density of capillaries that deliver oxygen to working muscles. It teaches your body to burn fat efficiently as fuel. And it does all of this with minimal stress on your muscles, joints and connective tissue.

In other words: easy runs are where endurance is built.

But here's the catch. All of those adaptations only happen at genuinely easy effort. Push too hard and your body shifts into a different energy system entirely — one that doesn't produce the same aerobic benefits and takes significantly longer to recover from.

Zone 1	Very Easy	60-65%	Conversational	Recovery runs
Zone 2	Easy	65-75%	Full sentences	Easy & long runs
Zone 3	Tempo	75-85%	Short sentences	Threshold work
Zone 4	Hard	85-92%	Barely speaking	Race pace & intervals
Zone 5	Max	92-100%	Cannot speak	Sprints

THE GREY ZONE PROBLEM

Most recreational runners live in what coaches call the grey zone — an effort level that's too hard to be truly easy but not hard enough to deliver the benefits of a genuine quality session.

Grey zone running is the worst of both worlds. It's hard enough to accumulate fatigue and increase injury risk but not intense enough to drive real performance adaptations. Day after day of grey zone training leaves you chronically tired, prone to injury and wondering why your fitness isn't improving despite putting in the work.

Sound familiar?

THE TWO PACE RULE

Here's a simple framework that transforms training for most runners:

Most of your runs should be easy. A small number should be genuinely hard.

The exact split varies by athlete and training phase, but a good starting point is 80% of your weekly volume at truly easy effort and 20% at quality effort — intervals, tempo runs, race pace work.

The key word is truly. Not sort-of-easy. Not comfortable-but-still-pushing. Genuinely, conversationally, almost-embarrassingly easy.

When runners first implement this properly — actually slowing down their easy days — they often report feeling better, recovering faster and performing noticeably better in their quality sessions within just a few weeks.

HOW TO KNOW IF YOU'RE RUNNING TOO FAST

The talk test — can you speak in full sentences without pausing? If not, slow down.

Recovery — are you arriving at your hard sessions already tired? Do your legs feel heavy most of the time? These are signs your easy days aren't easy enough.

Pace comparison — your easy pace should be significantly slower than your race pace. For most recreational runners we're talking 2-3 minutes per mile slower than half marathon pace. If the gap is smaller than that, something is off.

THE MENTAL SHIFT

The hardest part of slowing down is psychological. Slow running can feel like a waste of time. Like you're not working hard enough to deserve the miles. Like everyone around you is passing you and judging you.

None of that is true.

The runners passing you might be running their easy days too fast too. The slow miles you're logging are quietly building the aerobic engine that will carry you through your goal race. Every easy mile is an investment.

Slow down to go faster. It sounds counterintuitive. It works.

WHAT THIS LOOKS LIKE IN PRACTICE

If you're training for a half marathon on three to four runs per week, a well-structured week might look something like this:

Monday: Rest or easy cross training

Tuesday: Easy run with strides at the end

Wednesday: Quality session — intervals or tempo

Thursday: Rest or easy cross training

Friday: Easy run

Saturday: Long run at easy effort

Sunday: Rest

Notice how many of those runs are easy. That's intentional. That's the point.

NEED HELP FINDING YOUR EASY PACE?

If you're not sure what easy actually feels like for you, or you've been running in the grey zone for so long that slowing down feels impossible — this is exactly what coaching can help with.

I work with runners at every level to build smarter, more sustainable training plans that make the easy days easy and the hard days count.
