The Secrets to Building Running Endurance

I’ve been endurance running for a long time now. It’s one of my favorite things to do—I feel accomplished, invigorated, and at my best when running. But I also recognize that not everyone has such a positive experience with running. It can seem like a daunting sport to join. After all, how do you go from never running in your daily life to breezing through a 50-mile race? 

It seems like a lot. But most of us also know that endurance running has vast benefits. Getting started seems like such an ordeal! So, how do you go from couch potato to running aficionado?

But first…

8 Ways to Build Running Endurance from Scratch

New runners can build endurance by gradually increasing their mileage, improving aerobic capacity, and strengthening their muscles and cardiovascular system. Here are some key strategies:

#1 – Start with a Run/Walk Approach

If you’re a beginner, alternate running and walking. For example, start with a warm-up walk, then a 1-minute run followed by a 2-minute walk. Repeat. Some apps like Couch to 5K give you a built-in timer and help you gradually increase your running intervals.

#2 – Increase Mileage Gradually

Endurance running emphasizes – you guessed it – building endurance. And that takes time. Avoid overuse injuries by increasing your weekly mileage by no more than 10% per week. Consistency is key! You won’t be able to scale your mileage effectively if you don’t stick with it.

#3 – Run at a Conversational Pace

Most of your runs should be at an easy, conversational pace to build aerobic endurance. This means you should be able to comfortably hold a conversation while running. When you’re starting out, it’s about increasing endurance and mastering proper form – not speed. If you find yourself out of breath and unable to talk comfortably, slow your pace.

#4 – Incorporate Long Runs

A weekly long run, which should be 1–2 miles longer than your typical run, helps build endurance. This gradual increase in distance challenges your body and helps it adapt to longer runs. Yes, it will be tough, but it’s also a good way to challenge yourself without overextending. Remember, the key is to listen to your body and not push yourself too hard too soon.

#5 – Cross-Train and Strength Train

Cycling, swimming, or rowing can improve endurance without overloading your legs. Strength training helps prevent injuries. Endurance running uses your whole body. Strengthening your core, hips, abdominals, etc., can all help boost your performance.

#6 – Improve Running Efficiency

Form is crucial. It should be one of the first things you focus on. Not distance, not speed. Maintain good posture, avoid overstriding, and focus on a steady cadence (~170–180 steps per minute). It might help to compose a playlist of songs with the BPM matching your desired running cadence.

#7 – Fuel and Hydrate Properly

Have you ever put the wrong fuel in a car? It can destroy the engine. We’re not so different! If you want to “run” effectively, you need the right fuel. Eat whole, balanced meals with carbs, protein, and healthy fats. Stay hydrated before, during, and after runs.

#8 – Get Enough Rest

Remember, rest and recovery are just as important as the run itself when it comes to building endurance. It's during these periods that your body adapts and grows stronger. Make sure to prioritize quality sleep, rest days, and active recovery. This includes activities like stretching, foam rolling, and low-intensity exercises like swimming. Taking care of your body is a crucial part of the endurance running journey.

With these principles in mind, you’re ready to get running! Good luck and happy trials.
