Many people wonder if running on a treadmill is harder than running outside. The answer is not simple. It depends on many things like your body, pace, and the treadmill itself. In this article, we will explore if treadmills are harder to run on and why some people think so.
What Is a Treadmill?
A treadmill is a machine for running or walking in one place. The belt moves under your feet, and you try to keep up. It lets you exercise indoors, no matter the weather outside.
Running Outside vs. Running on a Treadmill
Running outside means you move forward on roads, tracks, or paths. You feel the wind and see different views. Your body moves naturally to keep balance.
On a treadmill, you stay in one place. The belt moves under your feet to help you run. The surface is flat and smooth.
Key Differences:
| Feature | Running Outside | Running on a Treadmill |
|---|---|---|
| Surface | Varies: grass, pavement, dirt | Flat, smooth belt |
| Wind and Weather | Present | None |
| Balance and Movement | Natural forward movement | Staying in place while belt moves |
| Impact on Joints | Depends on surface | Usually softer surface |
Why Some People Find Treadmills Harder
Some runners say treadmill running feels harder. But why? Here are some reasons:
- Different muscle use: Running on a moving belt needs muscles to work in new ways.
- No wind resistance: Outside, wind slows you down a bit, which helps your body work differently.
- Balance changes: On a treadmill, you must balance while the belt moves beneath you.
- Speed control: The treadmill sets the speed. You don’t have to push yourself to go faster.

Is Treadmill Running Easier?
Some say treadmills make running easier. The belt helps move your feet backward. It takes some effort off your legs.
Also, the flat surface means fewer bumps. Outside, you face hills, rocks, or uneven ground. These can make running harder.
What Does Science Say?
Studies show treadmill running burns similar calories as outdoor running. But the body works a little differently.
One study found runners use slightly less energy on treadmills. This is because the moving belt helps the foot lift off the ground.
However, some people feel tired faster on treadmills. This may be due to boredom or lack of natural scenery.

Tips to Make Treadmill Running Easier
If you find treadmills hard, try these tips:
- Adjust the incline: Set the treadmill to 1% incline. This mimics outdoor running.
- Use intervals: Change speed to keep your body active and avoid boredom.
- Focus on posture: Keep your body straight and relaxed.
- Look forward: Don’t stare down at your feet. This helps balance.
- Wear good shoes: Shoes with good support reduce impact.
Benefits of Running on a Treadmill
Despite some challenges, treadmills have many benefits:
- You can run anytime, even when it rains or snows.
- The surface is softer, which is good for joints.
- You can track your speed, distance, and calories easily.
- It is safer if you run in a busy city or dark area.
- You control the speed and incline to match your fitness level.
Benefits of Running Outside
Running outside also has great benefits:
- Fresh air and nature can improve mood.
- Varied terrain helps build strength and balance.
- You get natural sunlight, which is good for vitamin D.
- It can be more fun because of changing views.
- Wind resistance makes your body work harder.
Who Should Use a Treadmill?
Treadmills are good for many people:
- Beginners who want to start running safely.
- People with joint pain who need softer surfaces.
- Those who want to run when weather is bad.
- People who like to watch TV or listen to music while running.
- Athletes who want to control pace and incline precisely.
Frequently Asked Questions
Is Running On A Treadmill Harder Than Outside Running?
Treadmill running feels different because the belt moves under your feet. It can be easier since there is no wind resistance. Yet, some find it harder to keep balance or pace.
Why Do Treadmills Feel Harder To Run On?
Treadmills force you to keep a steady pace without breaks. The flat surface and lack of fresh air can make it feel tougher. Also, mental focus is higher indoors.
Does Treadmill Running Burn More Calories Than Outdoor Running?
Treadmill running burns similar calories to outdoor running at the same speed. Incline settings on treadmills can increase calorie burn. Running outside may burn more due to wind and terrain changes.
How Does Treadmill Speed Compare To Outdoor Speed?
Treadmill speed is consistent and controlled. Outdoor speed varies with terrain, wind, and traffic. Many runners find treadmill speed feels faster or slower than outside.
Conclusion
So, are treadmills harder to run on? It depends. Some find them easier because the belt helps move feet. Others feel they are harder due to balance and muscle use.
Both treadmill and outdoor running have good points. You can choose what fits your needs and goals best.
Try both ways if you can. Listen to your body. The best exercise is the one you enjoy and can do regularly.
