How to Increase Running Stamina: 6 Tips for Building Endurance

Nearly every runner wants to learn how to run longer and faster. How do you increase stamina for running if you’re brand-new to the sport? How do you build stamina for running when you’re a veteran?

If you’re new to running and you aren’t already in decent cardiovascular shape, you know how hard it can be to run very far—or very fast. If you’re a more advanced runner, you know exactly what it felt like and the consistency and time it can take to learn how to increase running stamina and endurance.

But how do you build stamina if you’re a brand-new or seasoned runner? Great question!

Even if you’re just starting out, it doesn’t take a miracle to improve running stamina. We’ve all been there at the beginning. It can feel tough to be sucking wind with your legs on fire after just a few minutes of running when you’re starting out.

However, it only gets better. It’s no secret how to build endurance for running and improve your stamina—you just need the dedication, motivation, and commitment to making each mile count. Before you know it, you’ll be running longer and experiencing the joys of runner’s high. We’re here to help you get there!

How to Increase Stamina for Running

Below, we’ll show you everything you need to know to learn how to build up endurance for running. In fact, most of these tips will build more than your running endurance—you’ll have better stamina for cycling, swimming, hiking, and really any cardio-based activity.

1. Be Consistent to Improve Stamina

There’s no quick fix to increasing running stamina–you’ve got to be consistent to yield the results you want. There are simply no shortcuts in learning how to build stamina. Training on a regular schedule teaches your body to adapt to the amount of work you’re putting in.

Let’s say you’re just starting out with running and you want to know how to increase your running stamina. Make a plan that incorporates running longer and farther every week–and commit to it.

For example, if you’re running three times a week for 20 minutes, increase the amount of time you run and the number of times you run every week incrementally.

For the first week, add one run (for a total of four runs) and add five minutes to each run.

On week #2, add another five minutes to each run. You’ll be running for 40 minutes four times a week.

For the third week, add five more minutes to each run, for 45 minutes of running four times per week.

On week #5, add another run so you’re running 45 minutes five times per week.

For the sixth week, bump up one of your runs to 60 minutes, and keep the others at 45.

Look at that! In just six weeks, you went from running 90 minutes total to 240 minutes total. Little bits of time add up and your body will respond well to the gradual increase. However, listen to your body. If you’re feeling sluggish, slow it down and adjust as needed.

2. Incorporate Tempo Runs

Not only does it matter how far and long you run to learn how to improve your stamina—it matters what type of running workouts you are doing. Tempo runs are typically a shorter distance–but at a much quicker pace.

The benefit here is that running at a faster clip will make running at an easy “endurance” pace will feel easier, and it will make you a stronger, faster runner. If you’re anything like me as a runner, you might hate tempo runs at first but will learn to love the thrill of a shorter, intense workout.

Here’s an example of a good tempo run for someone who is used to running about 35-40 miles per week.

  1. Start with a quick warm up to loosen your muscles.
  2. Run “comfortably hard” for 20 minutes–about 20% harder than your easy pace. We aren’t quite going for race pace, but you should definitely be breathing harder than a normal training run.
  3. Finish up with a cool down and some dynamic stretching to limit soreness and help prevent injury.

3. Get Some Cross-Training In

If you’re a die-hard runner like I used to be, cross-training isn’t your first choice. It’s tempting to only focus on running when you’re learning how to increase endurance, but it’s a lot of impact on your legs and entire body. Plus, cross-training has a lot of endurance-increasing benefits!

As long as it’s a cardiovascular activity, it’s going to improve your stamina and endurance without all that pounding on your legs. One or two days a week, incorporate a few of the following into your workout schedule:

  • Outdoor biking or an indoor spin class–it will get your heart pounding!
  • Swimming laps–also good for sore muscles!
  • Elliptical training
  • Tabata workouts

Plus, cross-training helps you from burning out and prevents overuse injuries.

4. Add in Strength Training

If you want to build your stamina, you need strong muscles that will support your entire body with each stride. That’s where strength training can make a huge difference in developing stamina and endurance.

Plus, weaving in strength training doesn’t have to take a ton of time. You can get a solid strength session done in five minutes. Follow along with Nate for a five-minute full-body workout filled with squat jumps and hand-release push-ups that will have your heart pounding and muscles burning–in a good way!

5. Eat Right!

The foods you put into your body play a giant role in fueling your stamina and endurance. If you aren’t eating healthy, nutritious foods, your body simply won’t have what it needs to increase run farther and increase stamina.

First of all, make sure you’re eating enough. One of the things most runners love about running is that it burns A LOT of calories. Even if you’re trying to lose weight, you still need to consume enough calories to fuel your run–and your entire day.

I’m not a big fan of counting calories–life’s too short! But, if you’re trying to lose weight or get a good sense of how much you should be eating, try this calorie calculator for runners.

Now, there’s a flipside to this. Just because you’re running a lot doesn’t mean you eat as much as you want. Depending on your size, a five-mile run burns around 500 calories. A large milkshake or double cheeseburger can easily contain many more calories than that–and it’s going to weigh you down rather than help increase your stamina.

The bottom line? Make wise food choices (while allowing yourself to indulge occasionally). Think lean meats, fruits, vegetables, healthy grains, and low-fat dairy. Don’t overthink it too much–food is meant to be enjoyed and nourish our bodies!

6. Get A Running Buddy

Have you ever had someone in your life push you to help make you better at something? It could be sports, your career, your attitude, or your diet–basically, just about anything.

You can also use the help of a running buddy to learn how to increase your running stamina–especially if they are a more experienced runner than you are. When I was in college, I used to try training with runners who were a little bit faster than me and would push me to go just a bit farther than I would on my own, and it certainly did wonders for my running stamina!

How do you find a running buddy? Ask a coworker who you know is into running, join a running Meetup group, or look up local running clubs in your area. As a bonus, running buddies also help keep you motivated and consistent when you know someone is counting on you to run with them.

Frequently Asked Questions

We hear plenty of questions around this topic, so we thought we’d include a few of our most frequently asked questions covering everything from building stamina to improving speed.

How can I increase stamina in a week?

Really, you can’t. Stamina takes time to build and improve. You break down your body as you push it past its current capacity, and you get the endurance gains during the recovery phase—and a week isn’t long enough for this entire process.

If you need to increase your stamina before a big race or event, we recommend tapering. This won’t necessarily build your endurance—however, it’ll ensure you hit the starting line fresh and ready to go (which can feel like a big stamina boost).

How to build vs how to improve running endurance?

Building running endurance from nothing is different than improving it once you’ve plateaued. When you’re new to the sport, it’s all about slowly increasing your running volume while mitigating injury. The more volume you can tack on each week while remaining in your body’s adaptation zone (rather than overload zone), the more stamina you’ll build.

However, once you’ve built a solid base of endurance, putting on the stamina gains isn’t as easy. You’ll need to start mixing in tempo runs, longer runs, and a nice mix of cross-training to build your aerobic capacity without getting injured.

It’s a delicate balance.

How long does it take to build stamina?

Well, it depends. Every runner’s body adapts differently, so it might take longer (or shorter) for you to build a certain level of stamina. Your training, nutrition, and life stresses will all impact this progression.

However, making even slight stamina gains takes a solid amount of time. You have to put in the right amount of activity and stress to push your body past its current capacity, but you have to make sure it’s not too much to dip into the realm of overuse or overtraining.

Once you’ve pushed this capacity, your body will adapt and grow stronger to deal with the demands. This is where you build stamina. Sometimes, this will take a week or 2. However, if you push too hard, you might not many any gains at all—you might lose fitness. Again, it’s a delicate balance.

How to Build Running Endurance for Beginners

Brand new to running? Here are a few additional tips that’ll set you on the right track to building endurance (the right way):

  • Start slow: Go slower than you think you need to. It’s not a race (yet). Training for a marathon is just that—a marathon. Don’t think you need to tack on the miles or the pace from the get-go. Give your body time to adapt.
  • Focus on recovery: You build running endurance during recovery—not the actual runs. Your job is to push your push during workouts and then give it the time and recovery it needs to adapt and grow stronger.
  • Improve running form: Don’t worry too much about nailing the right running form on your first week or even your first month. Try to find what feels right, whether that’s a heel stride, midfoot strike, or forefoot strike.
  • Keep up your cadence: You’ll face less aches and fewer injuries with a higher cadence. We recommend trying to shoot for anywhere from 170-190 steps per minute. If you’re not there yet, don’t worry. Just try to increase it a little bit each week.
