Why is My Running Not Improving

Ever feel like you’re putting in the miles but not seeing the improvement you expect?

I’ve felt stuck too, running hard yet going nowhere fast.

There was a time when I ran five days a week and still didn’t get any faster or last any longer

Plateaus happen to all of us, even the most dedicated runners.

But don’t lose hope—there are strategies to break those plateaus!

Let’s look at the common reasons your running might be stalling—and how you can overcome them.

Overtraining: Are You Pushing Too Hard?

One mistake I see all the time (and I’ve made it myself!) is overtraining.

It’s easy to think that just more running will make you faster, but pushing too hard can backfire. I remember when I started getting serious about my mileage—I was convinced that running every day would get me to my goals faster.

But I ended up burnt out, sluggish, and even slower than before Turns out, more isn’t always better.

But don’t just take my word for it.

Research from the Journal of Sports Medicine shows that adequate sleep and scheduled rest days are linked to reduced injury rates and improved performance in endurance athletes.

The Fix:

Finding the right balance is key. Alternate between hard and easy days, and take at least one full rest day per week. Back when I was overtraining, adding in rest days was a game-changer.

Try this: Do your interval training or tempo runs on Monday, Wednesday, and Saturday, and keep Tuesday, Thursday, and Friday as easy days. Sunday? That’s your day to relax and recover.

Keep an eye out for overtraining signs such as poor sleep, fatigue, or a higher heart rate.—and back off if needed.

Not Eating Enough: Is Your Fuel Running Low?

I found this out through some tough lessons. At one point, I thought that cutting calories would help me lean out and get faster at the same time.

Spoiler: It didn’t.

Skimping on fuel left me feeling tired, sluggish, and unmotivated.

Your body needs fuel to perform, plain and simple.

Not eating enough can sabotage both your workouts and your progress

The Fix:

Make sure you’re fueling adequately to match your training.

You’ll likely need between 2,400 and 3,000 calories daily as a runner.

Focus on eating whole foods: plenty of carbs from fruits, veggies, and grains to keep your energy up, protein to help your muscles recover, and healthy fats.

Hydration is key, too. I aim for about 60 to 90 ounces of water daily, depending on how hard or long I run. It’s a simple thing, but staying hydrated can make a difference.

The Weather: Running in Extremes

If you’ve ever run in 90-degree heat with humidity so thick you feel like you’re wading through water, you know what I’m talking about.

I’ve had more than a few runs where I thought, “Why am I so slow today?”—only to realize I was pushing myself through brutal conditions.

Running in extremes—scorching heat or freezing cold—can seriously affect your performance.

The Fix:

Ignore your pace and focus on the effort when the weather turns nasty

Leave the GPS at home and listen to your body on hot or cold days.

Harsh conditions can make your runs much more challenging, so don’t beat yourself up if your pace isn’t what it normally is. The effort you’re putting in will make you stronger over time.

I like to think of those tough-weather runs as character builders—they might be brutal in the moment, but they’re setting me up for better days ahead.

Doing the Same Runs: Mix It Up

I used to fall into the habit of doing the same 5-mile route at the same pace every day.

And you know what?

I hit a plateau fast.

Your body adapts fast, so you need to vary your training—speedwork, hills, long, slow miles—you’ll stagnate.

Don’t take my word for it.

According to a study published in Medicine & Science in Sports & Exercise, high-intensity interval training (HIIT) can improve aerobic capacity and promote performance gains in runners.

The Fix:

Add variety to your week!

If you’re used to steady-state runs, toss in some interval or fartlek sessions.

Not every run must be hard, but give it your all when it’s time to push.

I remember my first fartlek session—I thought I was going to hate it, but it ended up being a fun way to break out of my rut.

Laziness: Are You Being Consistent?

I’ve had weeks where life got busy, and I missed more runs than I could admit.

Skipping a run now and then might seem harmless, but those missed sessions can add up and slow your progress.

The truth is, consistent effort is crucial for improvement.. The American College of Sports Medicine advises a gradual increase in training intensity to prevent overtraining and improve athletic endurance.

The Fix:

Set a realistic training schedule. Maybe you can’t run six days a week, and that’s okay.

Commit to a number of days that fit your lifestyle and stick to it.

I’ve found that having a goal—chasing a new personal best or running for a cause—keeps me motivated.

When I don’t feel like running, I remind myself why I’m doing it in the first place.

Age: Embrace the Change

I hate to admit it, but age has slowed me down, too. VO2 max (your body’s ability to use oxygen) starts to drop after age 40, affecting performance.

By hitting 50, you may have lost up to 20% of your aerobic power.

It’s a tough pill, but I’ve learned that accepting this change doesn’t mean I can’t improve.

The Fix:

You can’t stop the clock, but you can keep training smart.

Continue running, but don’t forget to incorporate strength and balance work to maintain muscle mass and agility. I added in regular strength sessions and noticed a big difference—not just in my running but how I felt daily.

I may not be as fast as I was at 25, but I’m running stronger and smarter now.

Not Enough Sleep: Are You Resting Enough?

Sleep has always been my Achilles’ heel.

I prioritized everything else—work, family, training—over sleep for a long time.

But once I started taking rest seriously, my performance skyrocketed.

Sleep is when your body recovers and gets stronger. Skimp on it; you’re missing out on some of your best potential gains.

The Fix:

Aim for 7-9 hours of quality sleep per night.

Develop a relaxing bedtime routine, avoid heavy meals or caffeine late in the day, and keep a consistent sleep schedule.

I’ve found that once I started treating sleep like part of my training, everything improved—from my energy levels to my race times.
