The truth about easy pace - Run With Run Club

The Most Common Training Mistake

You check Strava after your "easy" run. You averaged 5:00/km. Your training partner ran 5:15/km. You feel good about going faster. You post it. You get kudos.

You also just sabotaged your next hard workout.

Running easy runs too hard is the single most common mistake I see. Not just with beginners - with runners chasing Boston qualifiers, breaking 3 hours, trying to run under 1:30 for a half marathon.

What "Easy" Actually Means

An easy run should be done at a pace where:

You can hold a full conversation (not just short sentences)
Your heart rate stays in Zone 2 (roughly 60-75% of max HR)
You could maintain this pace for hours if you had to
You finish feeling like you could run more

Reality check: If you're breathing through your mouth the whole time, it's not easy. If you can't talk, it's not easy.

Why It Matters

1. Your Hard Days Need to Be HARD

Training works through contrast. You need easy days to be truly easy so your hard days can be genuinely hard. If everything is medium effort, nothing is providing the stimulus you need for improvement.

When you run easy runs too hard, you accumulate fatigue that prevents you from hitting the paces you need on interval day or tempo day. Your hard workout becomes a mediocre slog.

2. You're Not Building Your Aerobic Base

Easy running teaches your body to burn fat for fuel, build new capillaries, increase mitochondrial density, and improve running economy. But these adaptations only happen in Zone 2 - the true easy zone.

When you push into Zone 3 (moderate effort), you shift the training stimulus. You're not easy enough to build aerobic capacity, and you're not hard enough to improve your lactate threshold. You're in no-man's-land.

3. Injury Risk Compounds

Every run creates micro-damage to your muscles and connective tissue. Your body repairs this during recovery. But if you never truly recover because your "easy" days aren't easy, the damage accumulates.

This is how runners end up with overuse injuries despite following a plan that "should" be manageable.

How Slow Should You Actually Go?

Here's the uncomfortable truth: Your easy pace should be 1:00-1:30 per kilometer slower than your marathon pace. Maybe even 2:00/km slower if you're tired or it's hot.

Example: I can race a marathon at 4:40/km pace. My easy runs? Usually 5:30-5:40/km. Sometimes slower. When I was chasing my 3:18, I had easy runs that averaged 5:40/km. I didn't run my PB despite this. I ran it because of this.

The Ego Problem

I get it. Running slow feels wrong. It feels like you're not training hard enough. It feels like you're wasting time. And when you see other people running faster on their "recovery" runs, you feel like you're falling behind.

This is your ego talking. Not your physiology.

The runners winning races and hitting PBs? They're running slow on their easy days. Slower than you think. Check the training logs of elite marathoners - you'll see plenty of 5:30-6:00/km easy runs.

How to Fix It Right Now

1. Use Heart Rate, Not Pace

Pace varies with terrain, weather, fatigue, and stress. Heart rate doesn't lie. Get a basic heart rate monitor and run your easy runs in Zone 2 (60-75% of max HR).

2. Do the Talk Test

If you can't speak in full sentences, slow down. This is non-negotiable.

3. Hide Your Pace on Easy Days

Cover your watch. Don't look at your pace during easy runs. Only check your heart rate. Your ego can't hurt you if you don't give it the data.

4. Reframe What "Good" Means

A good easy run isn't one where you averaged fast pace. It's one where you stayed in Zone 2, accumulated time on your feet, and set yourself up to crush your next hard workout.

The Bottom Line

If you want to run faster, you need to run slower. Not during every run - but during your easy runs, which should be 70-80% of your weekly volume.

Slow down to speed up. It's not a cliché. It's physiology.
