Running a 10K or a half marathon without walking or stopping might feel like an impossible mission when even a short jog leaves you breathless. But to get there, you need to build two key skills: endurance and stamina.
The good news: These aren’t fixed traits—they’re qualities you can train, no matter where you’re starting from. Yes, it takes time and patience, especially in the beginning. But the payoff is worth it: you’ll run longer, feel stronger, and recover faster.
In this article, we’ll break down what stamina and endurance are—and share proven ways to build both from the ground up.

What is stamina?
Stamina is your body’s ability to sustain prolonged physical or mental effort. Think of it as your go power: how long you can push yourself at or near your limits before fatigue forces you to slow down or stop.
In running, stamina lets you hold a certain pace without burning out too early.
What is endurance?
Endurance refers to how long your body can keep going during physical activity. It’s more about duration than intensity—how far or how long you can keep moving at any effort level.
Long slow runs are classic endurance builders, as they train your aerobic system to deliver oxygen to muscles efficiently.
How do stamina and endurance benefit running performance?
These two qualities are closely connected. Endurance allows you to run farther; stamina helps you hold a challenging pace longer. Together, they:
- Improve your running economy (less energy wasted)
- Delay fatigue and improve recovery
- Make workouts and races feel easier over time
When both are developed, you can run longer, faster, and more confidently.
So how do you build these two essential qualities when you’re starting from zero? Here are 10 tips that work—no matter your current fitness level.
10 tips to build endurance and stamina
1. Start slow and stay consistent
If you’re starting from scratch, the first and hardest lesson is patience. You don’t need to sprint—or even run the whole time. Walk-run intervals are a proven method to safely build your base.
Try this: alternate 1–2 minutes of running with 2–4 minutes of walking for 20–30 minutes total, three times a week. As you get stronger, reduce the walk time and increase the run segments. Your body adapts through repetition.
2. Create a training plan
A plan gives structure to your running, helping you balance intensity and recovery. You don’t need anything fancy—just a roadmap that gradually increases duration and variety.

3. Follow the 10% rule
One of the most common mistakes beginners make is doing too much, too soon. To avoid injury, never increase your weekly mileage or long run distance by more than 10% at a time.
For example: if you run 10K this week, aim for no more than 11K next week. It may feel slow—but this approach prevents burnout and injuries, and keeps your progress steady.
4. Train your aerobic base
The foundation of both endurance and stamina is your aerobic system. That means running at an easy, conversational pace—where you can talk in full sentences without gasping for air.
These “easy runs” might not feel impressive, but they build the cardiovascular capacity, capillaries, and mitochondrial efficiency you need for all other types of training.
Spend at least 70–80% of your training time at this intensity.
5. Add strength training 1–2x a week
Running is repetitive and impact-heavy, so your muscles and joints need support. Strength training—especially for the glutes, core, hamstrings, and calves—improves muscular endurance and running economy.
No need for a gym: bodyweight squats, lunges, planks, step-ups, and resistance band work go a long way. Two short sessions a week can reduce injury risk and help you run with better form.

6. Do short bursts of faster effort (progressively)
Once you’ve built a few weeks of easy running, you can sprinkle in short surges of faster running. These might be 20–30 second pickups at the end of an easy run, or strides (controlled accelerations over 80–100 meters).
This type of effort trains your body to handle pace changes and boosts your running efficiency. But keep them occasional and low-stress in the early stages—think spice, not the main course.
7. Do plyometrics
Plyometric exercises (like jump squats, bounding, or skipping drills) improve your running power and neuromuscular coordination. They help your muscles contract more quickly and efficiently—which translates to better stamina at a race pace.
Start with one session per week of 10–15 minutes, using low reps and full recovery. As always, form matters more than speed.
8. Run longer tempo runs
Tempo runs teach your body to sustain a challenging but manageable pace over time. This is stamina training in its purest form.
A classic beginner tempo run might be 15–20 minutes at a “comfortably hard” pace—where you can speak in short phrases but wouldn’t want to hold a conversation.
These workouts improve your lactate threshold, allowing you to run faster without accumulating fatigue.
9. Run 800-meter intervals (Yasso method)
Yasso 800s are a specific type of interval training that builds both stamina and endurance. The classic format is simple: run 800 meters (or about half a mile) at a steady, hard pace, followed by equal jogging recovery.
Start with 2–3 repeats and gradually build to 6–8. They’re tough but effective—and a favorite of marathoners for a reason.
Important reminder: Yasso 800s are best suited for runners who already have a solid aerobic base, typically at least 2–3 months of consistent running (3+ times per week).
They’re a moderately advanced workout that places both aerobic and muscular demands on the body, and doing them too early can increase the risk of injury.
10. Cross-train with cycling
Low-impact cardio like cycling helps develop cardiovascular endurance without the wear and tear of running. It’s ideal for active recovery days or when you’re increasing mileage cautiously.
Aim for one cross-training session per week. Keep the intensity moderate, and focus on spinning at a high cadence (90+ RPM) to simulate the leg turnover you want in running.

Start where you are—progress comes with time
You don’t need elite genes to build endurance and stamina. What matters most is consistency and patience.
Start small, keep showing up, and listen to your body. Over time, you’ll find that the same run that once left you gasping will feel—dare we say it—almost easy.
