What are common causes of tiredness when running?

You may be asking yourself: “Why do I get tired so easily on runs?”

It’s common to experience short periods of tiredness and fatigue when running and in between runs, especially after a long or demanding run.

You may struggle to breath when running, or your legs may feel heavy when you run.

Here are some common causes of tiredness and fatigue:

  • Lack of sleep
  • Lack of adequate recovery time in between runs
  • Insufficient fuel intake
  • Poor nutrition
  • Stress and anxiety
  • Hormone imbalance
  • Iron deficiency

If you regularly experience periods of tiredness and fatigue, then I suggest you seek help from a healthcare professional who will be able to assist you in identifying a cause.

Many tests can be performed nowadays to identify underlying causes of tiredness and fatigue, with blood tests being one of them.

How to run without getting tired

In order to run for longer without getting so tired, you need to build up your running endurance and stamina.

The golden rule to increase running stamina and endurance is consistency.

This means making running a regular habit and training consistently and progressing at regular intervals.

By training consistently, you increase your aerobic capacity (also known as your VO2 max or running economy) and strengthen your muscles.

If you do all of these things, you can expect to see a improvement within 2 to 3 months.

How to run faster without getting tired

Running speed is something that many runners look to improve once they have achieved a good base level of fitness.

Speed training like interval training is a great way to build your speed, endurance and stamina.

According to a 2020 study on training and physical performance in recreational runners, “training sessions that include continuous exercise performed at both low and high intensity levels” are beneficial for running performance.

The study added that “sessions of variable intensity (such as interval training) represent the training methods most often used to improve performance in endurance competitive events”.

Interval training is basically alternating periods of high-intensity effort (fast running or sprinting) with periods of low-intensity effort (slow running or walking).

A typical interval training session lasts anywhere between 5-30 minutes.

Here is a sample interval training workout to try during your next speed training session:

  • Walk for two or three minutes as a pre-warm up
  • Run 10 minutes at a comfortable pace to warm up.
  • Run 6 x 2 minutes at a very challenging pace.
  • Follow every interval with one minute of walking and one minute of jogging to catch your breath and recover.
  • Cool down by running at a comfortable pace for five minutes then walk for three minutes.

When it comes to running faster, remember that speed should always follow endurance.

In other words, work to increase running stamina and endurance first before you focus on improving your speed.

Running endurance and stamina training plan

Begin by adding extra runs into your training plan each week.

The key here is to include easy and long runs first, then graduate onto more speed focused sessions like interval training.

Strength training can also be added to help improve running performance.

Weeks 1 to 4

  • 3 to 4 easy runs per week – each run should be 30 minutes or more
  • 1 long run per week – anything between 4 to 25 miles depending on the distance event you are training for.

Weeks 5 to 10

  • 3 to 4 easy runs per week – each run should be 30 minutes or more
  • 1 long run per week – anything between 4 to 25 miles depending on the distance event you are training for.
  • 1 to 2 speed training sessions per week (e.g. interval training or tempo running)
  • 1 strength training session per week

Most half marathon and marathon training plans will build up distance slowly over a matter of weeks, but you should increase your running time by 5-10 minutes or add 0.5 to 1 mile each time.

You should also run at a conversational pace, in other words, don’t overdo it! It should be easy to hold a conversation without getting out of breath.

Many runners try to complete a long run too fast and end up struggling at the end or, even worse, end up injuring themselves because it was too much too soon.

Remember that speed should always follow endurance.

Therefore you need to build a solid base of endurance before you can start tackling more challenging training sessions like intervals and tempo running.

8 tips to run for longer without getting so tired

#1 Remember to warm up

A warm up is integral to any race – whether you’re running a 5k, 10k or half marathon.

It tells your brain that you’re about to do some serious exercise and gets your muscles ready so they can perform at peak efficiency.

A warm up has one key objective: to prevent injury and to get your heart rate up and blood flowing to your muscles.

A good warm up should leave you energised but not tired. If you push it too hard you may risk injury or poor performance during your race.

There are many versions of warm ups out there depending on race duration, your fitness levels and running experience.

At its core a proper warm up consists of two main parts: jogging to get your heart racing and dynamic stretches to loosen your muscles. You can also include running drills and accelerations in this.

Here are a few example dynamic stretches and running drills that you can perform before your run:

Dynamic stretches

  • Leg swings
  • Hamstring sweeps
  • Side shuffles
  • High skips
  • Fast feet

Running drills

  • Butt kicks
  • High knees
  • A-skips and B-skips
  • Carioca drill
  • Straight leg bounds

#2 Pace yourself

One of the challenges of longer runs is learning how to pace your run so you don’t tire yourself out too quickly. You don’t want to run too fast, yet you don’t want to run too slow.

Pacing is all about experimentation. The more you run, the better you become judging your pace and whether you need to go faster or slower.

You will undoubtedly feel fresher at the start of a run so the temptation is to go fast from the get go, but you should try and avoid this.

Dependent upon the distance, your pace and effort will change. The first mile may feel like the slowest as your body warms up and gets used to the movement.

This is why a warm-up is so important for your run – you will soon get into your stride.

To really understand what pace you should be running at, I suggest you use a running pace calculator to work out how fast (or slow) you should be running.

A pace calculator works by giving you your pace per mile for a given distance. Simply enter any two variables – pace, time or distance – and the pace calculator will determine your pace.

I recommend the Active.com pace calculator as it allows you to work out your pace using the variables above for a range of different distances.

#3 Strength train

Strength training is not the most obvious choice for runners when trying to run for longer without getting so tired.

The fact is strength training makes you a stronger, faster and more efficient runner, as well as helping to prevent common running injuries.

The key to strength training for runners is to keep it simple and focus on strength workouts that target all the main muscle groups that you use when running (also called ‘compound movements’).

Here is a sample strength workout that you either do on a designated strength training day or after an easy run. Complete 3 sets of 12-15 reps of each exercise, with 1 minute rest in between each set:

  • Squat
  • Reverse lunge
  • Single-leg glute bridge
  • Kneel to stands
  • Plank (hold for 30-45 seconds)
  • Russian twist
  • Press up
  • Tricep dips

#4 Listen to your body

Endurance running requires a lot of physical and mental stamina.

When you’re on a long run and you’re really struggling, it’s important to listen to your body to really hone in on what it is telling you.

Ask yourself: why are you struggling on your run today?

When training for longer distances it can be all too easy to get carried away and run all the time. Whilst it’s great to be excited about running, overtraining can be detrimental to your performance in the long term.

A good way to combat overtraining is to practice mindful running. Mindful running is essentially about being more mentally connected with your movement and not being distracted when you run.

Try turning off your music and really listen to how it feels to run. If your legs start to tremble, for example, you know it’s time to slow down.

Likewise, if you start to feel a niggling injury, you know it’s time to put the breaks on a bit whilst you let your body recover.

Mindful running works best when you’re out on a solo run. Try it at least once a week so you can really have time to practice your breathing and listening to your body.

#5 Fuel your body properly

As your mileage increases, you need to fuel your body appropriately. Your muscles need additional fuel to power you through a longer run.

Your performance on a long run suffers without proper fuel. Not fueling your body properly can put you at greater risk of injury and may affect your immune system.

If you run early in the morning, it is important to eat adequately both on the morning of and leading up to the run. You don’t have to eat a large meal, but the goal is get a burst of energy to get you started.

What to eat before your run

Some examples of food to eat before your run include:

  • Toast with jam
  • Yoghurt and granola
  • Banana with peanut butter
  • Avocado on toast
  • A hard boiled egg and toast.

The key is to get a good mixture of carbohydrates, glucose (a form of sugar), lean protein and fats. The amount you eat will depend on how much time you have before you start your run.

If you have 30 minutes or less, the focus should be on a carb-rich snack. If you have between 1-2 hours, the focus should be on carbs, lean protein and fats.

What to eat after your run

It’s also worth noting the importance of fueling your body after a run. A good post-recovery fuel plan optimises recovery and muscle repair. Once your run is over, eat a meal within two hours and try and include:

#6 Carb load

Carb loading is a key component for being able to run for longer without getting so tired.

Essentially, the process of carb loading is all about giving your body the extra energy reserves it needs to keep you going on your long runs.

Carb loading is most beneficial for runs that are 90 minutes or longer, and normally starts up to six days ahead of the run.

It is ideal for any energy-depleting exercise like running or cycling, where you know you’re going to be burning off a lot of energy in a short space of time.

In the week or so ahead of your long run, if you carb load you can expect to eat an extra 1-3 servings of carbohydrates.

The types of carbs you could eat include:

  • Pasta
  • Pancakes
  • Peanut butter
  • Bread
  • Jacket potatoes
  • Energy bars
  • Porridge
  • Wholegrain rice and salmon

Be warned, however, carb loading doesn’t give you a free pass to eat whatever you like, so choose your food options wisely!

Keep eating your greens, continue to consume lots of fruits and veggies, and stay hydrated.

#7 Stay hydrated

The goal of hydration is to reduce fluid loss through sweat, prevent fatigue, stop your muscles from cramping and prevent dehydration.

A simple way to tell if your body is dehydrated is to check the colour of your urine.

  • If your urine is a pale yellow colour, it means your body is hydrated.
  • If it’s a dark yellow or dark brown, you need to be drinking more water!

It can be difficult to get the right amount of water before a run as you don’t want to be nipping to the loo every two minutes.

My advice is to have at least one glass of water before you start your run – a sports drink is also good for giving you a burst of glucose before your run.

Don’t forget to drink lots of water after your run to replace some of the fluids lost during the run (through sweat) and to rehydrate the body.
