Why Am I Not Getting Faster? 9 Potential Reasons

The other week I posted on Instagram about how it’s possible to get faster as we age and after we have babies. I had several mother runners reach out to me frustrated about running slower and wondering, “why am I not getting faster?”

I could feel their frustration—because I have been there! And, often times we think that if we aren’t getting faster, if we are running SLOWER, or we have a fitness plateau it’s because we aren’t doing enough.

But often times (and especially for busy mother runners), it’s quite the opposite. It’s that we need to do less and get more of things like fuel and SLEEP.

My Story

When I started training with my coach, my runs and workouts started tanking. Easy runs felt so hard. And I couldn’t hit my paces on workouts.

Lifestyle changes such as supplements, fueling, and more sleep helped me run faster.

After one terrible track session, I talked to my coach. He urged me to ensure I was fueling within 30 minutes of running and to get bloodwork done.

After resistance on my end, I listened and it was a gamechanger. Fueling before harder workouts and refueling with carbs and protein soon after helped me recover faster so I could be ready for the next training session.

My bloodwork revealed a host of issues (one of the first articles I ever wrote about on my site details them) including a hormone imbalance and very low ferritin. I took supplements, focused on my diet, and began to feel better and perform better.

It was clear that my training wasn’t the culprit for running slow. It was other factors such as food and my hormones.

Many people who think they are running too slow, point the finger at themselves, thinking it’s them. They are destined to be slow or that their training isn’t enough.

Why are my runs getting slower?

There are many reasons outside running that may explain why you aren’t getting faster.

But, there could be a variety of reasons why your runs are getting slower.

With the athletes that I coach, I always ensure areas such as sleep are optimized before we start adding to their training. If an athlete thinks they’ve plateaued or are not improving, I don’t start adding in harder speed workouts. Instead, we talk about what else is going on in their life.

Other factors such as sleep or life stress are almost always the culprit behind slower running. Once we brainstorm ways to sleep more, eat better, manage levels, and relieve stress, they begin to feel better and run faster.

Of course, training may be the culprit—and looking at how you’re feeling and responding to training stimulus will help guide your training.

In this article, I’m going to review 9 reasons for why you may not be running faster plus what helps you get faster.

So, let’s roll.

9 Reasons Why You’re Not Getting Faster at Running

  1. Lack of Sleep.

Sleep is where PRs are made. Yup, it’s true.

When you run, you’re your muscles breakdown and have microtears. During your sleep is when your body recovers, building back your tissues so that they’re stronger.

When you don’t sleep enough, you not only don’t recover as well or strengthen as much, you also hurt performance. Studies show that even just one night of poor sleep can impair performance.

Unfortunately, as mother runners, getting enough sleep is often not in our control. Honestly, I get annoyed when people point fingers at those who are sleep-deprived—like it’s our fault—like we are staying up late scrolling or binging on Netflix.

No, it’s because our children want us to lay with them until they fall asleep, or are sick, or are waking up a gazillion times a night, or the dog threw up. Adding insult to injury is our menstrual cycle which can disrupt sleep during certain phases.

Personally, sleep is the hardest thing to balance when chasing running goals as a mom. Perhaps, that’s why it’s the first place I look when one of my athletes is running slower, dealing with illness, or fighting running injuries.

If you are feeling exhausted or rundown, then there is a good chance you aren’t getting enough shuteye. If you’re not getting the recommended 7 to 8.5 hours a night, then chances are you need to optimize your sleep.

So, control what you can control. Establish a good sleep routine. Avoid doom scrolling before bed. Aim to get to bed around the same time every night and wake up around the same time every morning.

If you can lay down for a rest or a bit of a cat nap during the day, do it (even if you don’t feel like you need to). And sleep in on rest days as much as your kids will let you know.

I advise against adding volume or intensity until you are sleeping enough most nights. That can lead to injury or illness.

  1. Not fueling properly.

What you eat and when can essentially make or break your training.

If you skip eating carbs before runs longer than an hour, don’t fuel during long runs, and don’t refuel within 30-60 minutes after long runs and hard workouts, you aren’t going to recover well.

And if you don’t recover well, your running performance will plateau. How do I know this? Well, science and also, I experienced this personally.

Related: Why You Shouldn’t Intermittent Fast and Run

When my kids were really young, I felt like I didn’t have time to eat before or after I ran. It was out the door as quickly as possible and back into mom mode immediately upon the return of my run. I also tried intermittent fasting one summer which may have contributed to my plantar fascia injury.

During this time, I rarely felt fresh during my training and did not hit my paces. But once I became intentional about my fueling, my running improved and was quite frankly, much more enjoyable. My legs felt bouncy and fresh.

If you don’t think about your fueling—start now!

It doesn’t have to be complicated:

  • Grab simple carbs like a plain bagel or some graham crackers before you head out the door.
  • Bring some Maurten gels for long runs and take every thirty minutes.
  • And refuel with protein and carbs like a bagel and peanut butter, smoothie, oatmeal, or whatever your tummy fancies when you get home.

Also, bear in mind that your age can impact what your body may need. If you are a master’s runner like me, you may need more protein then you needed in your 20s and 30s.

  1. Vitamin deficiency

Another thing I look at when my athletes aren’t training to their capability or are feeling unusually sluggish is their blood levels.

I will ask that they get their bloodwork done to ensure all their levels including their vitamins and minerals are within normal ranges.

Iron (ferritin which are iron stores) and B12 are common deficiencies in runners, especially female runners that can impact performance not to mention energy levels.

Once again, I know this from personal experience. When my running was tanking, I learned that I was deficient in many vitamins and minerals including a ferritin level of 14 (ideally it would be about 50).

You can see your primary care practitioner or use a company like InsideTracker to get your levels and recommendations. (Save on a test here).

Often times, supplements and lifestyle changes (e.g. cooking in a cast iron pan for more iron) can help you increase your levels so you can start feeling and running better.

  1. Hormone Imbalance

When I was diagnosed with a hormone imbalance after having my second child, I was shocked but also kind of relieved. It helped explain why I felt so tired all the time, cranky, and was running slow.

It made me wonder how many people are walking around with hormone imbalances, feeling terrible and acting unlike themselves and thinking it’s the new norm—especially moms.

Thankfully, regularly checking my levels and taking supplements solved the problem.

So, just as I advise checking your vitamin and mineral levels, I advise getting your hormones checked if you aren’t feeling or running like yourself.

Our hormones are like dominoes and if one is off, the others will be thrown off, too, which can essentially affect all your bodily functions. It’s a good idea to get a full blood panel at least once, if not twice a year.

  1. Life stress.

Running is stressful to the body—and so is work and family and life in general. And your body doesn’t know the difference between these different causes of stress.

So, if you’re in the throes of toddler tantrums or middle-of-the-night wake-ups or a move or a job promotion or family drama, your body’s going to respond the same way with elevated cortisol levels.

Elevated cortisol levels can impact your running by creating a state of chronic muscle breakdown plus suppressed immune function setting the stage for illness and injury.

You can help manage life stress by taking time for yourself, trying to remove things off your plate, meditating, having quiet time in the morning before the family wakes up, and ensuring that running is relieving stress—not adding more of it.

You can also talk to your doctor about taking an Adrenal Support supplement to help manage your cortisol levels.

  1. Weather

If you feel slow running in heat and humidity, then guess what? You’re normal. Running in hot and humid weather is like running at altitude—it’s challenging and pays off in the end with fitness gains.

Your body is working overtime to keep your skin cool and protect you from overheating. This means that it’s drawing water from your blood which can make it thicker, supplying less oxygen to your working muscles. It also means your heart rate is elevated, making your effort feel harder.

If you want to run by pace in hot weather, you need to adjust the paces for hot weather.

Or, you should run by effort which is what I recommend.

If you’re worried you getting slower because all your paces are off in the summer, my advice to you is to keep your eyes off your watch and just keep putting in the work. Your consistency will pay off when the weather cools in the fall in the form of PRs.

  1. Time of Day

    Post these reasons for running slower.

The time of day you run can greatly impact your pace:

  • After work or at the end of the day: you may be exhausted and need some time to shift your focus to your training.
  • Early morning: you may also need more time to wake up.
  • Middle of the day: you may be hungry and need to figure out how to fuel your run before you lunch.

I run in the early morning, but I’ve learned that I need about an hour to drink coffee and allow my body and mind to wake up before I head out the door. I’ve also learned that those first 3 miles are going to be extra slow.

Changing the time of day in which you run can impact how your body feels. Try to run your workouts during the same time so that you can ensure you feel your best. Also, learn what your body needs to perform—whether that be coffee or an extra mile to warm-up.

  1. Your Training

Finally, sometimes your training is the reason why you’re running slower.

  • If you run the same speed and distance every day, you aren’t going to get faster.
  • If you run with a low heart rate for every run, you may actually get slower.
  • Conversely, if you run too fast on your easy runs or run consecutive hard days, you compromise your recovery and your performance. You are also at risk for burnout, injury and illness.

In general, variety is the key for running faster.

Run some runs:

  • fast
  • slow
  • long
  • short
  • hilly, and
  • flat

Alternate easy and hard days to balance rest and rest. Take rest days and a week of reduced mileage once a month or so.  Use strides to build a bridge to faster running. (Read my interview with Runner’s World about the importance of strides.)

Often, your training can shed light on the types of runs you need to focus on to get faster. According to respected running coach and author Brad Hudson you can tell if your:

  • Neuromuscular fitness is lagging: sluggish in workouts and up hills, thresholds breathing is okay but legs feel tired. Attack with strides and speed for 2-3 weeks.
  • Aerobic fitness is lacking: long runs are hard, speed workouts you get tired on last reps, and with tempos your legs feel fast but breathing is labored. Attack with some added miles and a bit longer progression runs for 2-3 weeks.
  • Specific endurance is lacking: you have a tough time holding race pace, fatigue early in pace specific workouts and you don’t do well in your tune-ups. add some race specific workouts (at pace or a bit faster) in for 2-3 weeks.
  1. Training Adaptation. 

If you’re starting a new training plan, there may be a period in which you feel like you’re going backwards. Easy runs may be slower than usual as your body adapts to the training stress.

This happened to me this year and served as a good reminder to put my head down and just do the work. Don’t overanalyze the run.

This stage can last a couple of weeks. Just continue to run what feels best for you in the moment and allow your body to adapt and become more efficient. Do the little things to ensure it has what it needs to adjust and strengthen.

By focusing on your overall health—not only when you’re running—you’re bound to feel better and run faster.
