Our testers loved that the BowFlex also has a 22- by 60-inch running deck with plenty of space to accommodate runners over 6 feet. And the ergonomics are up to par, with a built-in fan, large storage areas for your phone, and a water bottle holder. It’s worth noting that the upfront cost of this machine is pretty hefty—and it doesn’t come with many free workouts. Instead, full access to the BowFlex’s streaming classes requires a $149 yearly JRNY subscription to access trainer-led workouts, data tracking, streaming entertainment, and scenic runs (which is not far off the Peloton’s app’s annual $129 cost, though the full membership is $240 annually).
Let’s Compare the Costs of These Treadmills
How We Tested Running Treadmills
Large pieces of cardio equipment tend to be significant investments, and treadmills are some of the priciest out there. With that in mind, we had our team of runners and athletes put more than two dozen cardio machines to the test before lining up the ones that get our stamp of approval.
We tested treadmills for weeks to get a real-life feel of how they stand up to different types of workouts and how they stack up in terms of performance and durability. We looked at nearly every top brand to evaluate features including customization, noise, construction, ergonomics, foldability, and programming—and identify the best treadmill for every type of runner. Here’s more about our fitness testing process.
Benefits of a Treadmill
The main perk of running on a treadmill is that they provide a controlled environment and allow you to stay consistent with your training—regardless of the weather or time of day. You can adjust every aspect of your run, from the incline to the speed to the duration, making it easier to track progress and train for a specific event.
Compared to running on harder surfaces like roads, cushioned treadmills are built to absorb impact, which reduces stress on joints, Burke says. “So if you’re recovering from an injury, especially a leg or hip injury, a treadmill can help you slowly reintroduce running since it can absorb some of the impact of your body weight.”
What to Look for in a Treadmill for Runners
If you plan to use your treadmill for running—and not just incline walking or getting in more steps—you’ll need to find a machine that can handle the action. Here’s what to consider before buying.
Budget
“You get what you pay for” applies to treadmills, too. Lower-priced machines often use cheaper materials, like plastic and thin steel, which can mean faster wear and tear. They’re often not built for high-mileage running, so over time, a lower-end treadmill may end up costing you more cash in repairs. Joshua Fitchitt, CPT and Senior Vice President of Fitness with the Bay Club says that lower-priced treadmills also often compromise on motor power, belt size, and cushioning; they may also lack advanced features like decline and interactive training programs. “While Bluetooth, heart rate monitoring, and other tech are usually a sign of a higher-quality treadmill (merely because it shows the recency of the tread manufacturing), make and material take precedence over these factors,” Centenari adds.
Durability
If longevity is your priority, look for running treadmills with a robust frame, a powerful motor (preferably 3.5 CHP or higher), and a high weight capacity (around 400 pounds), Fitchitt says. Durable treadmills often feature a thicker running surface, larger rollers, and better shock absorption systems—all of which contribute to a smoother, more reliable running experience. So how can you tell you’re running on a higher quality tread? “There will be limited ‘bounce’ or redundant movement and shake under your feet,” Centenari says.
Speed
Your average treadmill goes from 1 to 12 mph while some of the more advanced models can hit up to 15 mph. A beginner runner building a base and running for prolonged periods of time will probably remain under 7 mph, Centenari says, but if you’re trying to add sprint or interval work into your training, you’ll likely touch higher speeds for lower amounts of time. “For beginners or joggers, a treadmill with a max speed of 10 mph can still be adequate,” Fitchitt says.
Cushion
Cushion technology is meant to offer shock absorption and provide a softer landing, almost mimicking outdoor terrain. “The cushioning system in a treadmill absorbs the shock of your bodyweight as your foot strikes the belt, reducing the impact of the force on your ankle, knee and hip,” Burke says. Higher-quality cushioning systems can help prevent common running injuries such as stress fractures and shin splints, she says. But while you want a softer belt, you also don’t want it to feel like a trampoline — too much cushion can limit your power production, Centenari says.
Incline and Decline Options
Having incline and decline capabilities means your indoor run will feel more like an outdoor run. That’s especially great for people training for a race, but runners looking to progress will also benefit. “Incline or hill work is a great way to provide varied stimulus for a runner who is used to working on flat terrain,” Centenari says. “Especially if you’re returning from injury and working toward building intensity, hill running is a good alternative to speed work, which can often be too intense in the beginning of rehab processes.” Meanwhile, decline running can help you prepare for downhill portions of races, Fitchitt says.
How to Safely Install a Treadmill at Home
Before buying a treadmill for running, you’ll want to triple-check the treadmill’s dimensions against the space you have available at home. Always place the treadmill on a flat surface and follow the manufacturer’s assembly instructions. If you’re installing the treadmill on your own, make sure to read the user manual and follow it closely. If your new treadmill is really large or heavy or if it has extra tech features—or if you just don’t want to bother with flipping through the lengthy manual—consider professional assembly. Some brands offer this as an add-on at checkout.
FAQs
What is the best size treadmill for running?
A deck size of about 20 inches by 60 inches is recommended to accommodate a full running stride. Beginner runners tend to overstride, so having a longer belt will feel more comfortable as they acclimate and progress.
Is it better to run or jog on a treadmill?
Treadmills are great for running and jogging, but it also depends on your skill level. Beginner runners should start by jogging and focusing on stride mechanics and easy breathing while intermediate to advanced runners can play around with higher speeds and inclines.
Do treadmills work well for long-distance running?
They can, but long runs on treadmills often feel monotonous, and that can lead to fatigue and mechanical errors. Advanced runners should vary the paces and elevations to mimic an outdoor run. Streaming classes and entertainment options can also help with making a long run fly by.
What is the best incline treadmill for runners?
Most running treadmills go up to 12% incline, but some more advanced models can hit 15% incline.
