Today we will learn how to increase running stamina. I remember saying, that I would never run a marathon. The distance seemed too challenging. 7 marathons later I can promise you that sometime in the future, a distance you found challenging will feel more manageable. When that happens, it means you’ve increased your running stamina.
But how do you increase your running stamina? Building endurance comes from consistency, which means running multiple times per week for multiple weeks to accumulate fitness. Let’s be real about it, there are no shortcuts to increasing running stamina.
The first step to building running stamina
Assess your current aerobic base and build on that. Whether you’re looking to complete your first 5k or an experienced runner looking to increase your stamina for the final stages of a marathon as I did a few years back, the rule of “too much too soon” holds true. Please, be mindful of increasing your runs too rapidly, or resting too little, will ultimately lead to performance plateaus or injury.
How to build stamina for running
Consistency in running is key
To increase your aerobic capacity and improve your endurance, you need to train consistently. Consistent training will build your aerobic base, increase your aerobic capacity (which is how much oxygen your muscles can use) and strengthen your muscles.
When you begin to add extra runs to your week, they should be easy and slow – speed follows endurance! You should aim for three to four sessions per week for 30 minutes or more. Aim to make one of these sessions your long run where you plan to go farther than any of your other runs that week.
Time is short, long runs are boring. Then sprint!
Studies have shown that six short sprint interval training sessions increase endurance as traditional long runs do. With work, kids and everything else we have to handle in our day-to-day lives long runs can be time-consuming.
Sprint intervals require less time and volume, so you can still build your running stamina without adding many more miles to your workout schedule.
The glory of a long run
Practice is everything. To run further, you’ve got to practice running farther. You can increase your long run by five or ten minutes. Or, you can add 0.8 –1.6 km to your current long-run distance. It might not sound like much but it begins to add up.
When you get into a bigger volume of training for a half marathon or marathon, your long run should be roughly 30-50% of your total distance for the week.
Do your long run at a slow and sustainable pace (many people try to run their long run too fast and struggle to finish). Go slowly and just focus on covering the distance. Remember, speed follows endurance.
Increase running stamina with this algorithm
First, calculate your total planned running distance for the week. Then, enter it here:[total distance] x .30 = [single long run distance]
Once you can comfortably run this distance, multiply your total miles by .4 and then by .5
First of all, let’s talk about what a tempo run actually is.
A tempo run is a shorter run at a pace that is difficult to sustain. For instance, a 40-minute run at your typical 20-minute pace.
All types of workouts such as fartleks, interval training, and tempo running are all exercises to improve running endurance. Tempo runs are a particularly effective way to increase running stamina. These runs are normally run over a shorter distance but at a higher pace than at which you usually train.
Tempo runs should take 20-40 minutes for runners preparing for any distance under a marathon. For those preparing to run marathons and ultras, tempo runs should last as long as 60 minutes. They should not be an all-out effort that has you gasping for breath, but a challenging pace that you feel you can maintain over the duration of the run.
How to increase running speed in tempo runs
Aim to keep up a pace of 70% of your max effort for the entire tempo run. Do one tempo run per week. Try to increase your speed every time.
Eating for endurance
Another item on this list we have to be extremely honest about is our diet and how much of what we eat (and when) plays into our running performance. That means getting enough carbs, fats, and protein. Here are a few helpful guidelines:
Pre-run carbo-loading is most effective before a morning run. If your primary exercise is running, you can get as much as 50-65% of your macronutrient intake from carbohydrates.
Fats are an essential part of runners’ diets. They are vital to cells and nerve function. Fats insulate and protect organs. And, when your glycogen stores deplete in an endurance run, the body uses fats as fuel. If you tend to sweat a lot during your runs or feel chilled due to sweating, then fat intake is even more important: having enough fats in the body can help you avoid exercise-associated hypothermia.
How to increase stamina? Increase protein intake! Eating protein after a run helps repair muscle damage and maintain muscle mass.
If you’re running for more than an hour, you should be fueling during your run. In-race fueling can be tricky, as many runners experience digestive issues. Studies show that simple carbohydrate-focused drinks, gels, and bars work.
Take it easy: Recovery
Longer runs necessitate longer recoveries. There are some ways to ensure that you’re recovering efficiently between sessions.
Sleeping well is how to improve stamina for running. Sleep is crucial to recovery. While moderate exercise can help sleep, high training volume can hamper it. Add at least 30 minutes to your regular sleep routine on days you plan to run long.
After a run, drink plenty of water. That means getting more fluid than you lost in sweating (like, 150% more!). Drinking something with high sodium content, like a sports drink, can also help the body retain fluids.
Improve your running economy
Working on your running technique will make you a more efficient runner. If you run efficiently, you will be able to run farther without feeling as tired as you will use less energy. Talk to a running coach about your running style and in what ways you could be able to run more efficiently.
Trick your mind
Running farther than you ever have before can be tough, but remember that you can do it.
Mentally preparing yourself for your longest run of the week will make it easier. Rather than wondering how to build stamina for running long, think of your run in sections.
Focus on one mile at a time, one 5k at a time, or one marathon at a time. As soon as you achieve your initial goal, mentally evaluate your physical and emotional state. Can you run another mile, another 5k, or another marathon?
If the answer is yes, keep going! After all, a 10k with a slow 3k added on already sounds less scary than running 13k.
One extra tip from me on how to increase running stamina is to never skip strength training. Weightlifting and running go hand in hand and it will only make you stronger and faster to tackle every challenge that you set for yourself.
