Zone 2 Running: Why Slowing Down Might Be the Key to Getting Faster

The first time I intentionally started running in Zone 2, I felt like a terrible athlete.

Running slow felt wrong. Embarrassing, even. After years of associating effort with progress, easing back felt like failure. But it turned out to be one of the most important shifts I’ve ever made as a runner.

Why Running Slow Felt So Hard

I grew up with two older brothers who were deeply into sports and performance. I was always trying to keep up with them or beat them! That competitive mindset followed me everywhere.

For my high school soccer tryouts, we had to run two miles in 15 minutes or we were cut. In elementary school, we ran timed miles in gym class, and I always wanted to win. Speed was the standard. Faster was better. Effort meant success.

So when I was told to slow down, really slow down, it challenged everything I thought I knew about fitness.

The Mental Battle of Zone 2 Running

Zone 2 running forced a complete mindset shift. Instead of chasing pace, I had to focus on heart rate.

I would finish runs, look at my mile splits, and feel disappointed. The numbers felt painfully slow. I was used to running 8:30-minute miles. Now I was running 10-minute miles, sometimes slower. (Also, totally not knocking down people who run 10 min miles or slower, these paces are now my normal, every day paces!)

Then came the comparison trap.

I’d scroll through Strava and compare my easy runs to other runners’ workouts. I worried that if people saw my running time, they’d judge me, or worse, make fun of me.

Here’s the truth I had to remind myself constantly:

No one actually cares how fast or slow you run on Strava. I know I don’t look at someone’s time and think, “Wow, they ran so slow.”

That comparison almost kept me from sticking with Zone 2 training.

Key word: ALMOST!

What Happened When I Gave It Time

After a few weeks of consistent Zone 2 running, something changed.

I started to enjoy running again!

I wasn’t burnt out. I wasn’t waking up sore every morning. I wasn’t dealing with nagging injuries. Instead, I felt energized. Stronger. More consistent.

I could actually enjoy my easy runs instead of sprinting through them just to get them done.

Even better, my heart rate began to drop at the same easy pace, which was proof that my aerobic base was improving.

That’s when it clicked: slowing down wasn’t holding me back. It was building me up. 

The Real Benefits of Zone 2 Running

Zone 2 running isn’t about being lazy or unmotivated. It’s about training smarter.

Some of the biggest benefits include:

  • A stronger aerobic base that supports all running paces

  • Improved endurance without excessive fatigue

  • Lower injury risk due to reduced stress on the body

  • Faster recovery between workouts

  • Lower heart rate at the same pace

These benefits don’t show up overnight.

But they compound over time.

Easy Days Should Actually Be Easy

One of the most important lessons I’ve learned is this:

Keep the easy days easy, and the hard days hard.

A five-mile easy run should feel relaxed, almost like a brisk walk through the park! You should be able to hold a conversation. If you’re finishing an easy run exhausted, it’s no longer serving its purpose.

Running your easy days too fast doesn’t make you tougher.

It just makes you tired and often injured.

How Zone 2 Makes You Faster

Here’s the part that surprises a lot of runners:

Zone 2 running doesn’t make you slower, it actually makes you faster.

By keeping easy runs truly easy, you save energy for hard days. Speed workouts, tempo runs, and race-pace efforts become more effective because your body is actually recovered enough to execute them properly and hit those fast paces consistently.

It’s those quality hard efforts during speed workouts, not grinding through every single run, that lead to faster race-day results.

Put your effort where it matters most: your speed workouts.

If you try to push both your easy runs and your hard runs, you’re setting yourself up for burnout and injury. Consistency wins. Smart training wins.

The Takeaway

Zone 2 running requires patience. It requires humility. And yes, it requires letting go of your ego.

But if you stick with it, you’ll likely find what I did:

More enjoyment.
Fewer injuries.
Better consistency.
Stronger performance when it matters most.

Running slow isn’t a step backward.

Sometimes, it’s the smartest way forward.

Best Running Gels for Marathon Training: What Worked (and Didn’t) for Me

When I trained for my   first half marathon , my fueling strategy was simple: water. That was it. I remember hearing runners talk about taking gels during runs and honestly having no idea what they meant. I was able to run 10, 11, even 12 miles with only water, so I figured I would be fine, and technically, I was... But after every Saturday long run, my legs were completely exhausted. Heavy, sore, and slow to recover. At the time, I didn’t realize that the missing piece was  proper mid-run fueling . How I Learned the Importance of Fueling During Long Runs When I started training for my  first full marathon , I kept hearing the same advice: If you want strong legs and steady energy through 26.2 miles, you need to fuel with carbs during your runs. That’s when I finally started experimenting with running gels. Once I began taking gels during long runs, I immediately noticed the benefits: More consistent energy Stronger legs late in runs Faster recovery after long miles Fueli...

Why I Use the Runna App for Marathon Training (and Why It Actually Works When Used Correctly!)

Recently, there’s been a lot of online criticism aimed at running influencers who get injured, with much of the blame being placed on the Runna app. Many influencers are sponsored by Runna, so you often see them posting workouts, racing frequently, and unfortunately, sometimes dealing with injuries. But here’s the thing: running injuries are rarely caused by a single factor  and it’s not fair to blame an app. There are countless reasons runners get injured: increasing weekly mileage too quickly, skipping strength training, inadequate fueling, poor recovery, life stress, or running every run too hard. Placing all the responsibility on an AI training app oversimplifies a much more complex issue. I know this firsthand. During my first marathon training block, I developed IT band syndrome, and I wasn’t using any AI running app at all. I got injured because I ramped up my mileage too fast, didn’t strength train and ran nearly every run at a hard pace. Ironically, since I started us...

The Best Running Biker Shorts for Thick Thighs (No Ride Up, No Chafing)

I am a huge fan of biker shorts for running. If you have thicker thighs like me, you already know the struggle. Those cute, flowy running shorts? They might look great, but for me they lead to unimaginable chafing — no matter how much anti-chafe lotion I apply. After one too many painful runs, I made it my mission to find biker shorts that could actually survive long training blocks. Shorts that don’t ride up. Shorts that don’t cause chafing. Shorts that can carry you through marathon training. And most importantly — shorts that are affordable enough to buy in multiple colors without burning a hole in your wallet. If you’re part of the thicker thigh club, this list is for you. 🥇 My Top Pick: Colorfulkoala 6” Inseam Biker Shorts My number one go-to pair is the Colorfulkoala 6-inch inseam biker short . I own multiple pairs, and they are truly my favorite running shorts. They do not ride up. Not on short runs. Not on long runs. Not during speed work. They stay put! Why I love them: The 6...
