If you’re like many runners, especially starting out, you push the pace. Getting ready for a big race might make you do it too. Faster feels totally logical for getting good race times. This idea comes from common training principles people hear. Running culture loves speed, records dropping, and new shoes.

But maybe this fast way holds you back some? It sounds opposite what you think, we know it does. The experts agree though for going faster. You should train slower, much slower sometimes. Like really slow it way down, believe it.

A pro marathoner coach says easy runs are better. The easier you go, the better it really is for you. Most runners they do not do this by themselves. One coach sees athletes going too fast every workout.

So they are missing this crucial training zone. This part is often called Zone 2 training now. It is when your heart rate is low, maybe 60-70% max. Other smart people define Zone 2 a bit different. They say maybe 72 to 82 percent of max heart rate. The exact numbers you use dont matter much.

The main idea is keeping effort low for a long time. Running this slow pace might seem like you can skip it easily. Wanting to feel fast is a really strong feeling. But doing this slow stuff matters huge for improvement. It unlocks lots of great benefits overall for you. Like physical changes happen, your blood gets bigger.

Your heart too grows in size and strength from this. Imagine having more fuel and a stronger engine body. Consistent easy running helps build all these great things. A coach sums it up nicely for everyone. It helps build all the things we call improved fitness generally.

What does better fitness mean for you running? You can run races longer and shorter without feeling done. This capacity lets you keep faster times when race day arrives. It is easy to watch the numbers on smartwatches a lot. Zone 2 is defined by a heart rate range, true. But experts say do not just watch bpm data solely.

Heart monitors can be off sometimes, you know. Many things affect heart rate besides how hard you try. Like stress, or if you drank enough water, or weather conditions. A better way uses heart rate plus your pace.

And maybe most important is how hard it feels to you. Are you running miles slower than your hardest pace feels? Is your heart rate up but not super high yet? Does the effort feel easy, light, like you could talk fine?

If you can say yes to these questions, you are probably there. This perceived effort idea is important for figuring it out. It leads us to a simple, reliable method for finding slow enough. Ben Rosario, a pro running coach, says the talk test works. He says it sounds old school but really it is true.

If you cant have a conversation, you are not going slow. This means speaking full sentences or easy phrases too. This conversational pace is what many coaches mean mostly. It makes easy runs much more fun to do. You can run with friends and talk easily together.

This running boom now shows social side clearly. Run clubs and group runs are everywhere on social media. These clubs are not just for fast people chasing records always. They are built on sharing the running experience with others.

Often at a pace everyone can handle easily. A Nike coach named Jes Woods sees group power. She knows social context helps runners accept lower effort. If putting slow pace down to your group helps you run easy, she accepts it. It gives you a reason to keep pace chill for connection. Now, why slow down besides heart stuff?

Recovery is huge and injury prevention matters greatly. When you run fast often, impact force is high. Every step hits your body harder than a slow pace. This repeated impact stresses bones and tendons hard.

A physical therapist explains this connection well. Running faster more often adds up stress over time for you. This stress stacking can raise your risk for injury. Letting your body handle lower forces gives it a break. Recovery is super important in any training plan you make.

If you train hard days back-to-back, recovery suffers greatly. Your body needs time to fix and rebuild itself. Easy runs give your system this needed time back. So when you push hard, body is ready to adapt better. Slow training also helps body do specific things.

Things that do not happen when you push hard only. Training your system for low heart rate is key here. This helps build a strong base for speed later on. Zone 2 training is great for this specifically. Training in this zone builds mitochondria in your cells. They make energy for your body aerobically inside.

More mitochondria means you use energy better for running. You can go longer and recover quicker between workouts. Building mitochondria is not just slow miles forever though. It trains your body to use oxygen well when going slow. This base helps you build speed later on effectively. Without this base, speed work is harder and hurts more.

Think of training like building a house you live in. Speed work is like adding cool features on top. Slow running is putting in the foundation first. House of speed wont stand without base from easy miles.

A coach says slow running helps you run faster later. It is an investment for future speed, truly. He sees runner training all same pace sometimes. That pace is likely not fastest or truly easy pace.

It is probably somewhere in the middle ground pace. Training here too much hinders recovery for you. It stops body building that base it needs. This leads to feeling stuck and tired often. Just like the author felt when starting and hitting same 5K hard. That story connects with new runners easily.

Trying fastest every time does not work well. It is not good for getting better or race goals either. Sprinting and high intensity are needed too, absolutely. They improve force and give you a finish kick.

But they cannot be most of your training plan. Doing every run hard overwhelms body capacity always. It hurts recovery and limits how much you gain. Evidence from experts supports prioritizing the easy effort runs.

Beyond physical adaptations like increased blood volume and a stronger heart, slow running plays a vital role in injury prevention and recovery. Fast running subjects your body to high impact forces, while easy runs allow tissues to heal and rebuild—essential for sustainable training.

Think of slow running as the foundation of a house: without it, the “speed features” you add won’t stand. By prioritizing Zone 2 efforts—whether measured by heart rate, pace, or the “talk test”—you’ll build mitochondrial density, improve oxygen efficiency, and unlock faster race times. It’s not about avoiding speed, but investing in a base that lets you chase it effectively.
