Runners are creatures of habit. We roll out of bed at the crack of dawn to go for our run. Others head to local groups in the evening after work. Then there are those ambitious souls who sneak in a few miles at lunchtime. Regardless of your training habits, there’s one vulnerability to them all: the weather. But our best treadmills for serious runners are here to save the day (and your run).
Whether it’s raining, hailing, or 5000 degrees outside, a treadmill is the answer to your running problem. These treadmills could also be your best training companion if you need to train indoors for other reasons: safety, there are children to look after, or you are tired of the same old route.
If you are a distance runner, marathoner, or triathlete, you’ll want a treadmill with a powerful motor. Larger runners or those with a long stride need plenty of deck span for a healthy gait. Those who enjoy HIIT will need a treadmill that is fast and responsive. We know what to look for in a running treadmill because we are runners with different training goals and paces.
The top running treadmills let you go fast and as far as you want. They have training options that match your program’s needs. If you want to recover, build speed, or increase your endurance and VO2 max, there’s a treadmill on this list to consider.
NordicTrack Commercial 2450 Treadmill
What We Like:
- Softly cushioned deck
- 3.6 CHP motor
- 22” touchscreen
- iFIT training classes
- -3% to 12% incline
- Folding frame
- Hands-free training
Areas For Improvement:
- Minimal storage
- Limited onboard training programs
The adjustable touchscreen transports you to global locations so you can run through central Spain, traverse mountains in New Zealand, or enjoy a tour through the cobblestone streets of London (without navigating actual cobblestones!). Plus, you can pivot the screen to train off the treadmill. Best of all, the 2450 folds up to save space in your home.
The 2450 is a fantastic treadmill for runners of all fitness levels. The cushioning makes it comfortable for new runners, while the deck provides the proper support to facilitate a healthy running gait. The extra shock absorption is perfect for recovery days.
Weekend warriors will love the 2450 because they can train for any outdoor event with the Google Maps feature. On the touchscreen, draw out any map anywhere in the world and save it in iFit to run later! The 2450 will automatically incline and decline to match the actual terrain of your route, and you can watch Google images of each location as you run along.
Even long-distance marathoners will love the NordicTrack 2450. The cushioning provides excellent shock absorption for a comfortable run, and the 20” x 60” deck offers plenty of room for long strides. Distance and speed runners will particularly benefit from the 3.6 CHP motor, which can handle distance running and sprint sessions.
With all these features, we consider the NordicTrack Commercial 2450 a fantastic treadmill for runners, so we designated it our best treadmill for serious runners.

Sole F85 Treadmill
What We Like:
- Powerful 4.0 HP motor
- 375-lb weight capacity
- Folding frame
- 15.6” touchscreen
- Onboard programs and apps
- Lifetime frame and motor warranty
- Firm cushioning mimics road-running
Areas For Improvement:
- Non-adjustable touchscreen
- Less cushioned than the 2450
Another awesome element of the F85 is the 4.0 HP motor, which supports a speed range from 0.5 to 12 mph. It has large rollers for consistent, quiet belt motion and firm deck cushioning that resembles road running outdoors. It has 15 levels of incline and 6 levels of decline. You’ll want to train for your next race on the Sole F85.
The Sole F85 has a 15.6” touchscreen with training programs and fitness tests to help keep your runs structured and engaging. Another great way to keep yourself engaged on the F85 is by streaming from the 12 preloaded apps. These apps include Netflix, Hulu, Max, Amazon Prime Video, and Spotify – to name a few.
If the apps aren’t enough, you can screen mirror your phone to the screen to watch whatever you want. There is a wireless charging pad below the screen to charge your compatible phone and a device rack above the screen to put your phone or larger tablet. The content options are limitless.
All of these features pair well with the overall construction of the Sole F85. It is a hearty treadmill built to last and covered by a lifetime frame and motor warranty. It is also quiet to use in most homes so that you won’t disrupt others.
So, whether you’re a heavy runner looking for a treadmill that will keep up with you or just looking for a solid and durable running treadmill, we highly recommend the Sole F85.

NordicTrack X22i Incline Treadmill
What We Like:
- -6% to 40% incline range
- Very cushioned running surface
- iFIT running and hiking classes
- 22” touchscreen
- Automatic fan
- Hands-free training
- Google Maps routes
Areas For Improvement:
- Bouncy at high speeds
- iFIT requires Wi-Fi
- Does not fold
iFIT gives the X22i automated speed and incline, so the deck adjusts as you run to match the natural grade of the route. The gorgeous full-color touchscreen displays hundreds of outdoor running trails. I completed a run on the X22i that took me through the lush mountains of New Zealand. 45 minutes and 500 calories later, I didn’t want to leave the X22i and return to real life.
A few things I love about the Nordictrack X22i include the console, deck size and feel, and the training options. The X22i provides more cushioning and is better for steep hill training. Sydney did not enjoy the cushion’s bounciness while sprinting, but Kaleigh likes the extra help when tackling faster paces. They agreed that steady-state running on the X22i was a dream.
This sturdy treadmill is large (70” x 39” x 73”) and doesn’t fold up, so make sure you have enough space before purchasing. The step-up height on this machine is 14”, and the deck tilts to 31” off the floor when fully inclined, so consider your ceiling height, too. However, once you are on the X22i, you’ll never want to get off.

AssaultRunner Pro Treadmill
What We Like:
- Supports all speeds and abilities
- Well-priced for its quality
- Commercial-grade build
- 350-lb weight limit
- Electricity not required
- Slat belt cushioning
- Built-in programs and Bluetooth connectivity
Areas For Improvement:
- Manual treadmills require focus
- Limited storage
Our pick for the best overall manual treadmill is, hands down, the AssaultRunner Pro. This treadmill has an impressive build with a steel frame and uprights and a running belt that will last 150,000 miles. It is ideal for runners and athletes who want a treadmill that matches their endurance and speed. Plus, this deck encourages runners to adopt a more efficient stride.
The AssaultRunner Pro supports handles up to 350 lbs of weight, making it perfect for most runners. The treadmill weighs about 290 lbs, which is lighter than most manual treadmills. Still, it’s big and doesn’t fold up. Surprisingly, it is easy to move with its grab bar that lets you tilt the deck to engage the front wheels, though most users will want to find a dedicated space for it.
We know Assault Fitness as a brand that creates dependable, built-to-last equipment, and the AssaultRunner Pro is no exception. The console is Bluetooth-enabled and has onboard interval and target workouts. It effectively displays metrics like time, distance, speed, watts, and pace. It’s simple but perfect for a manual treadmill.
On the AssaultRunner Pro, runners of all abilities can track their workouts, burn more calories, log more miles, and run as fast as they can.

Horizon 7.8 AT Treadmill
What We Like:
- 4.0 HP motor
- Sprint 8 programming
- Spacious 22” x 60” running surface
- Intuitive speed and incline dials
- Folding frame
- 15% maximum incline
Areas For Improvement:
- Low-tech console
- No built-in video training programs
Another aspect that makes the 7.8 AT convenient for HIIT is the quick-dial adjustment buttons. These blue rollers on the console allow you to scroll to your desired speed and incline level quickly. There are also programmable interval keys and quick-adjust buttons.
The console is simple with an LCD screen, so it isn’t as fancy or high-tech as others on this list, but for those who prefer simplicity, we recommend this treadmill. The Horizon 7.8 AT includes onboard workout programs and the Sprint 8 training program for structured HIIT workouts.
This beefy treadmill is foldable and has a large 22” wide and 60” long deck. Its 375-lb weight limit makes it ideal for most runners, too. If you need to move it, you can do so with the transportation wheels, although this treadmill is 330 lbs and is best kept in a specific space in your home.
Overall, the Horizon 7.8 AT has a lot to offer. It’s comfortable with good deck cushioning, has a well-powered quick-adjusting motor, and is quiet.

Sole F63 Treadmill
What We Like:
- Reasonably priced
- 3.0 HP motor
- Onboard workouts
- Bluetooth speakers
- 20” x 60” deck
- Folding frame
- 325-lb weight limit
Areas For Improvement:
- No built-in video content
- Not ideal for marathon training
The Sole F63 has a 3.0 HP motor, which is the smallest motor size we recommend for running. With its 12 mph max speed and 15 incline levels, the F63 stands up to more expensive machines. It also helps that this treadmill supports up to 325 lbs. If you primarily train outside, the F63 is a solid option for a dedicated runner who needs a backup plan every now and then.
The 20” wide and 60” long deck make this treadmill great for running. This size supports all stride lengths. The deck also folds up, and the F63 can be moved fairly easily because of its four transport wheels. You can push it around when needed, which is very helpful for those who are short on space.
The F63 has a 6.5” LCD screen display with less tech than others on this list but still includes many features. It has onboard workouts and Bluetooth connectivity to Sole+, Zwift, and other apps. You can watch content from your device and play the sound through the F63’s speakers.
The Sole F63 does not require a subscription and does not have a touchscreen, but that doesn’t stop it from offering runners entertaining training options.

TrueForm Runner Treadmill
What We Like
- 450-lb weight limit
- Customizable color and running surface
- 20-year frame warranty
- Simple and effective display
- Promotes efficient running form
- Unlimited speed
- No electricity required
- Heavy-duty construction
Areas For Improvement:
- Very heavy
- Minimal console
- Not as beginner-friendly as others
The TrueForm Runner has a gentler curve than most manual treadmills to promote efficient running form. Athletes can burn up to 44% more calories on a manual treadmill since the belt is completely dependent on the speed of the runner for propulsion. Sloppy running makes running even harder on this treadmill, but good form makes it easier.
The TrueForm Runner helps improve running form and makes for a challenging workout. You can’t hide at the top of the deck, hugging the console for support. The slats won’t maintain an even speed unless you move back to the center of the curved deck, encouraging many runners to adopt a midfoot running strike.
Unlike motorized treadmills, where you have to tap a button and then wait for the speed to adjust, on a manual treadmill, the belt will speed up or slow down at the same time you do for a more natural feel. Thus, the TrueForm Runner is an excellent tool for HIIT training. Just come prepared with a training plan because the console does not have many onboard programs.

ProForm Pro 9000 Treadmill
What We Like:
- 22” touchscreen
- iFIT programming available
- Folding frame
- 20” x 60” running surface
- 300-lb weight capacity
- -3% to 12% incline range
Areas For Improvement:
- Not as cushioned as NordicTrack
- Screen does not pivot
The ProForm Pro 9000 offers iFIT, a subscription fitness platform. iFIT includes over 17,000 workouts for running, walking, jogging, hiking, boot camp, strength training, and even yoga! iFIT trainers automatically adjust your speed and incline during the class. The more you train with iFIT, the better the speed will match your fitness level.
Some workouts are 100% on the treadmill, while others incorporate off-treadmill moves. The 22” touchscreen lets you see the class more easily off the treadmill. While the screen does not pivot like the NordicTrack commercial series consoles, we think the Pro 9000’s screen size and quality are perfect for its price.
The Pro 9000 is adequately powered for serious running. With a 3.6 HP motor, you can run, walk, or jog at any pace. Households with multiple runners may want to consider the Nordictrack 2450, but the Pro 9000 offers plenty of power for most. The size and cushioning of the deck is well-engineered. The deck will support up to 300 pounds, declines to -3%, and inclines to 12%.
If you are looking for something that is both fun and reliable, the Pro 9000 is a great place to start.

Horizon 7.0 AT Treadmill
What We Like:
- Budget-friendly
- 20” x 60” running surface
- 12 mph
- 15% maximum incline
- Folding frame
- Onboard workouts
Areas For Improvement:
- Not ideal for high mileage
- Weak fan and speakers
The Horizon 7.0 AT has a quick-adjusting 3.0 HP motor, so it will handle your interval training and never keep you waiting for it to adjust. The quiet motor supports a 12 mph max speed and 15% incline. Considering how affordable this treadmill is, we love how fast and high the deck moves!
The 7.0 AT feels comfortable to run on. The deck cushioning provides moderate shock without feeling bouncy absorption on par with higher-end treadmills. The console is simple, with an LCD screen and 4 LED windows to show your workout metrics. The programs are standard, like ones you’d find on a commercial treadmill at your local gym.
The console also connects to other apps like Zwift to give you more training options. Plus, there’s a device rack at the top of the console for you to stream content from your phone or tablet. So, if you’re looking for a straightforward treadmill with a few extra training options, this is one to check out.

What to Consider when Buying a Treadmill for Running
Runners have specific needs that include power, size, and cushioning. Here’s a quick list of things to look for if you are in the market for a treadmill for running.
Enough Motor Power For Running
A small motor works fine for walking, but runners need a strong motor to power long distances and fast speeds. Motor power is paramount for marathoners, sprinters, or those who do HIIT. We recommend a motor that is at least 3.0HP for running and jogging. Closer to 4.0HP is better if you plan to do long distances, have multiple users, or are training daily for a race or event.
Enough Speed For Your Run
Smaller treadmills usually have a top speed of 10 mph (a 6-minute mile). If you run faster than this, then you’ll want something with a top speed closer to 12mph. Most motorized residential treadmills do not go faster than 12.5 mph. Check out a manual treadmill like a Woodway or TrueFit Runner if you want unlimited speed. This type of treadmill will go as fast as you can run.
Response Time
The response time is how quickly the treadmill reacts when you change a speed or incline setting. For those who enjoy sprints or HIIT intervals, a 3-5 second lag between settings may be too long. However, most treadmills are fine for steady-state runs with periodic adjustments.
We’ve found the most responsive motors are on the new Nordictrack treadmills (since they just upgraded the incline tech) and the Horizon 7.0-7.8AT lineup. These respond the fastest to incremental adjustments.
Incline and Hill Training
Training on an incline helps strengthen your leg muscles for a more balanced musculature when running. Newer treadmills with subscription programming include options such as hiking or trail running. NordicTrack and ProForm treadmills that feature iFIT offer outdoor hikes led by a personal trainer for a high-intensity but low-impact workout on your non-running days.
Finding An Affordable Treadmill For Running
Most of us have to factor price into any large purchase. Sure, you can spend a lot and get all the fancy features, but most buyers want to find the best—and most affordable—treadmill that will suit their needs. Our reviews provide a breakdown of both affordability and durability so you can evaluate what you really need and want on your treadmill.
Size of the Deck
It is important to have a running surface large enough to support a healthy running gait. Our treadmills are evaluated based on how much room they provide the runner (not just how big the machine is). Look for a running deck that is at least 20” x 60” long. Treadmills that are 55” long will work for walkers or those with shorter running strides.
Cushioning
Cushioning drastically impacts your treadmill runs. If you run long distances, cushioning helps absorb some of the impact that can be hard on your joints and spine over time. Larger runners will appreciate a bit more cushioning. The Nordictrack 2450 offers enough cushioning to keep you comfortable while its bounciness reduces the energy lost in your running stride.
Alternatively, firm cushioning replicates the experience of running on the road. If you will only run on the treadmill while training for a road race, a firm treadmill could help you prepare better. Firm cushioning also gives runners a sturdy platform to push off of at faster speeds.
Apps and Training Features
How do you like to train? Do you use Zwift? Do you prefer a subscription with classes and content?
Some treadmills have full-color touchscreens, while others are relatively simple with preloaded training programs. Not all runners want to pay for a subscription, so consider your budget and preferred training style before choosing a treadmill with a subscription service. Any treadmill that requires a subscription will also require wifi, so you’ll need a good internet connection.
Noise Output
When running indoors, noise matters! If you live upstairs from a neighbor or have a family or roommates, the noise of your treadmill may limit when and how often you can use it. Consider how noisy a treadmill is if you plan to train indoors. We include noise output in our reviews to help with this.
Roller Size and Belt Texture
Most people probably don’t think about the treadmill roller size, but it matters. The rollers move the belt along the surface of the deck. If the rollers are small, there is more tension and friction on the belt. It can wear out faster and have performance problems. Look for rollers that are close to or larger than 2.0”.
The belt texture affects how the belt feels underfoot, so we recommend a gently textured 2-ply belt for durability. A textured treadmill belt gives you plenty of traction for running fast and up a steep incline.
Warranty/Durability
Running requires a durable treadmill to support the high impact and strain on the motor. We recommend treadmills with at least a 5-year frame and motor warranty. A 10-year warranty indicates that it is designed to last. If it has a limited 1-year warranty, we recommend caution if you plan to use it for running.
Frequently Asked Questions
Does Running On A Treadmill Make You A Better Runner?
Running on a treadmill can make you a better runner. There are a few reasons for this:
Runners who own a treadmill can run more often.
A powerful treadmill allows runners to train at any time of day or night. It is an excellent solution if you work long hours, have kids or other responsibilities, or live in an area where weather limits training part of the year. Runners with treadmills can continue to train when gyms and running clubs are closed. A treadmill allows runners to run more miles conveniently in their homes.
Motorized treadmills have preset speed settings
Rather than pushing yourself to hold a certain speed, a motorized treadmill can challenge you to keep up with a set pace. It is a great training tool for improving your speed or time. Eventually, your body will be able to hold the pace with practice and improved conditioning. Forget your watch—you can trust your treadmill to keep you on track!
Treadmills allow for a greater range of incline training
If you are training for an outdoor event with lots of hills but live in a flat location, it can be hard to get the proper training done. A treadmill allows you to build a route that will be challenging (or easy!) and provide the right training. Rather than drive to a set location for hill training every morning, just hop on your treadmill and adjust the incline! It’s safer and more accessible.
A cushioned treadmill will allow you to train longer without getting injured
Running is high-impact. Even young, fit runners can suffer stress fractures or shin splints from too much outdoor running. Most treadmills provide a modest amount of cushioning because they are inherently softer than asphalt or concrete. Higher-end treadmills offer more cushioning, allowing you to reduce your injury risk.
What Treadmills Are Best For Serious Runners?
Our list above outlines our take on the best treadmills for serious runners. However, the type of running you plan to do will influence which treadmill is best for you. We recommend finding a treadmill with at least a 3.5 HP motor and a 20” x 60” running surface, especially if you plan to do all of your training indoors.
If you are a sprinter, look for a treadmill with a top speed at least equivalent to your fastest pace. Serious runners need power, size, and cushioning. The type of training provided on the treadmill also matters.
Are Treadmills Good For Running?
Running on a treadmill can be better than running outdoors. It is safer, more cushioned, and doable at any time of day. As long as the treadmill has sufficient motor power and is large enough to support your stride, a treadmill can be an excellent training tool for runners.
Outdoor runners often find treadmills to be debilitatingly boring. Video content can make a big difference. Many of the newer treadmills include video content filmed outdoors. Larger screens that fill the console make it feel like you are actually on the road. Additionally, smart treadmills incline and adjust speed automatically, allowing you to run hands-free like you would outside.
Treadmills are no longer torture devices that sit in a dusty basement only to be used on gloomy, rainy days! You can use and enjoy a treadmill indoors to benefit your running outdoors.
Are Treadmills Bad For Knees And Joints?
A treadmill is better for your knees than running on concrete or asphalt. Many treadmills on our best list include generous cushioning that will absorb much of the shock from running. Using a treadmill is a great option if you have sensitive knees or tender joints that could use a break from all the impact of running.
How Fast Is 7.0 On A Treadmill?
7 mph is about 8:30 per mile. Many treadmills provide miles per hour, kilometers per hour, and minutes per mile metrics as you run. The 2450 offers this feature right at the top of the screen.
