There’s a familiar routine for many of us: the hurried drive to the gym after a long day, the search for parking, and the hope that your favorite treadmill isn’t already taken. The desire to stay active often clashes with the reality of schedules, crowds, and membership fees. For years, I told myself that a home treadmill was an unaffordable luxury, a bulky piece of equipment destined to become an expensive coat rack. I was skeptical that a machine in the sub-thousand-dollar range could deliver the power, stability, and features needed for a truly challenging workout—especially one that could simulate the hill climbs I love. The alternative was to let fitness slide, succumbing to the convenience of the couch. But what if there was a middle ground? A machine that brought the core elements of a gym-quality workout into your living room without the premium price tag. That’s the promise of the THERUN Folding Incline Treadmill 3.5 HP, and it’s precisely the promise we set out to test.

What to Look for in a Home Treadmill Before You Buy
A treadmill is more than just an item; it’s a key solution for achieving consistent, convenient cardiovascular fitness regardless of the weather or time of day. It provides a controlled environment to walk, jog, or run, helping you manage weight, improve heart health, and reduce stress. The main benefit is removing the friction between the decision to exercise and the action itself. No more excuses about rain, darkness, or lack of time to get to the gym. A good home treadmill becomes a reliable partner in your health journey, always available for a quick walk or an intense training session.
The ideal customer for this type of product is someone facing a busy schedule, a parent juggling work and family, or anyone who prefers the privacy and comfort of their own home. It’s perfect for those looking to build a consistent fitness habit, from beginners to intermediate runners. However, it might not be suitable for elite athletes or marathoners who require exceptionally long running decks and commercial-grade motors for daily high-mileage training. Those users might need to invest in a non-folding, professional-grade machine. For individuals purely focused on walking while working, a more compact under-desk walking pad could be a better alternative.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Measure your available space carefully, both for when the treadmill is in use and when it’s folded. The THERUN’s unfolded dimensions are 60″D x 30″W x 51″H, and it folds to a more compact 31.1″L x 29.5″W x 54.7″H. Ensure you have enough clearance around the machine for safe operation and storage. The folding mechanism itself should be easy to use and secure.
- Capacity/Performance: This is the heart of the machine. Look at the motor’s horsepower (HP)—3.5 HP is excellent for this price range, supporting both walking and running without straining. Check the speed range (0.6-10 MPH) and auto incline (0-15%) to ensure it can challenge you as your fitness improves. Finally, confirm the maximum weight capacity (300 lbs for this model) to guarantee stability and durability.
- Materials & Durability: The frame material is a key indicator of longevity. The THERUN uses alloy steel, which provides a solid, stable base that doesn’t shake or wobble during intense runs. A heavier machine, while harder to move initially, often translates to a more robust and secure feel during use. The quality of the running belt (this one has a 5-layer belt) also contributes to both durability and user comfort.
- Ease of Use & Maintenance: A complicated machine gathers dust. Look for a clear, intuitive display and user-friendly controls, like the shortcut buttons on this model. Assembly is another factor; models that arrive mostly pre-assembled save significant time and frustration. For long-term care, consider how easy it is to access the belt for lubrication and cleaning, which is essential for smooth operation.
Keeping these factors in mind, the THERUN Folding Incline Treadmill 3.5 HP stands out in several areas, offering a compelling blend of power and practicality for home use. You can explore its detailed specifications here.

Unboxing the THERUN: First Impressions and Setup
The arrival of the THERUN Folding Incline Treadmill 3.5 HP is an event. The box is substantial, and at 145 pounds, this is not a one-person job. We recommend having a friend on hand to help move it into place. This initial heft, however, was our first positive indicator of its build quality. Lighter, cheaper treadmills we’ve tested often feel flimsy and unsafe; the sheer weight of the THERUN suggested a robust, alloy steel frame within. Upon opening the box, we were pleased to find the machine was nearly fully assembled. The main components—the motor, deck, and base—are a single unit. All that was required was to raise the console uprights and secure them with a few bolts. The instructions were clear, and the entire process took us less than 20 minutes from unboxing to plugging it in. This is a huge win, as confirmed by numerous users who praised the straightforward setup. Our first impression was of a machine that feels more expensive than it is—solid, well-constructed, with a clean black-and-orange aesthetic that looks sharp in a home gym setting.
Key Benefits
- Powerful 3.5 HP motor handles running and incline changes smoothly.
- Impressive 0-15% auto incline adds significant workout intensity.
- Sturdy alloy steel frame with a 300 lbs weight capacity feels secure.
- Extremely fast and simple assembly, arriving mostly pre-built.
- Folds easily to save space when not in use.
- Relatively quiet operation for its power class.
Potential Drawbacks
- Heavy machine (145 lbs) is difficult for one person to move.
- The included 1-year warranty is shorter than some premium competitors.
A Deep Dive into the THERUN’s On-Deck Performance
A treadmill’s spec sheet only tells part of the story. The real test is how it performs underfoot, day after day. We put the THERUN Folding Incline Treadmill 3.5 HP through a rigorous testing period involving everything from leisurely recovery walks to high-intensity interval training and grueling hill climbs. This is where the machine truly revealed its character, proving to be a surprisingly capable and reliable workhorse for a wide range of fitness levels.
The Heart of the Machine: Motor Power and Incline Performance
The standout feature, without a doubt, is the combination of its 3.5 HP motor and the 15-level auto incline. In a market saturated with underpowered motors that struggle at higher speeds, the THERUN’s power plant is a breath of fresh air. During our tests, the motor never felt strained, even when pushing the speed up to its 10 MPH limit. Transitions were smooth and responsive, without the lag or hesitation common in budget treadmills. This was particularly noticeable during interval sprints; the machine got up to speed quickly and reliably, allowing us to focus on our form rather than waiting for the belt to catch up.
The auto incline, however, is the real game-changer. It elevates the machine from a simple running platform to a versatile training tool. We found the incline adjustments to be fluid and surprisingly quiet. One user noted that it “smoothly transitions between levels… without any jerky movement,” and our experience was identical. Simulating a hill workout by ramping the incline up to 12% or 14% provided a serious challenge, engaging glutes and hamstrings far more effectively than a flat run and getting our heart rate up quickly. Another user looking to “simulate hiking” found it hit the mark perfectly, confirming its effectiveness for varied training styles. The ability to control both speed and incline from the handlebars is a fantastic ergonomic touch, preventing you from having to break your stride to reach for the main console. This powerful motor-incline duo is the core reason the THERUN Folding Incline Treadmill 3.5 HP delivers such exceptional value.
Build Quality and Running Experience: A Stable and Cushioned Ride
A powerful motor is useless if the frame can’t handle it. This is where the THERUN’s 145-pound alloy steel frame and 300-pound weight capacity pay dividends. Throughout our testing, from brisk walking to all-out running, the machine remained rock-solid. There was no unnerving shaking, wobbling, or rattling, which immediately instills a sense of confidence and safety. This stability is something many users, who had previously owned “very lightweight, cheap treadmills,” highlighted as a major upgrade and a key reason it’s “worth the price.”
The running deck itself measures 47.2 inches long by 17 inches wide. While elite runners with very long strides might seek out 55-60 inch decks, we found this size to be perfectly adequate for users up to 6 feet tall for both comfortable jogging and running. The deck is enhanced by a double shock absorption system, featuring 10 internal shock absorbers. This isn’t just marketing speak; we could feel the difference. The impact on our knees and ankles was noticeably softer compared to running on pavement, and even some other treadmills. As one user mentioned, their “joints don’t feel sore after a long session,” a critical benefit for long-term, sustainable fitness. The 5-layer belt provides good grip and feels durable underfoot, completing a running experience that is both secure and comfortable.
Design, Usability, and Smart Features
THERUN clearly focused on functional design over flashy, unnecessary extras. The console is straightforward and effective. The large digital LCD screen is easy to read, displaying all the essential metrics: speed, incline, time, distance, heart rate, and calories burned. The buttons are large, well-labeled, and responsive. We particularly appreciated the deep, stable cupholders—a small detail, but one that prevents water bottles from rattling and falling during a run, a common annoyance on other models.
The Spacesaver folding design works as advertised. A hydraulic arm assists in lifting the deck, and it locks securely into a vertical position. While it’s still a heavy machine to roll around, the ability to fold it up and reclaim floor space is essential for anyone without a dedicated gym room. It’s a feature that makes it “perfect for a garage setup without taking up much space.”
In terms of smart features, the Bluetooth connectivity is a welcome addition. It allows you to connect to fitness apps like ZWIFT, adding an interactive layer to your workouts. While the integration isn’t as seamless as on treadmills with built-in HD touchscreens costing three times as much, it provides valuable tracking and a more engaging experience for those who use it. For a machine in this price bracket, offering robust hardware and functional smart connectivity is a smart compromise that delivers maximum value. If you’re looking for a treadmill that nails the fundamentals of power, stability, and thoughtful design, the THERUN offers a feature set that’s hard to beat.
What Other Users Are Saying
Across the board, the sentiment from users is overwhelmingly positive, often centering on the machine’s surprising quality for its price. One user, an experienced athlete and ultra runner, stated they were “blown away by theRun treadmill” compared to big gym machines, praising its great cushioning and straightforward, effective features. Another person who was hesitant to upgrade from a walking pad felt this was the “best bang for my buck,” noting it works exactly as expected and has made a “huge difference” in their fitness journey.
The most commonly praised features are the sturdy build, quiet operation, and powerful auto incline. Many echo our findings, with comments like, “It feels sturdy, runs smoothly, and the incline feature makes workouts more fun and challenging.” The simple assembly is another frequent highlight, with multiple people reporting setup times of under 30 minutes. On the critical side, the most common piece of feedback is the machine’s weight, with several users reiterating that moving the box requires two people. A few isolated reports mentioned shipping damage, but those who engaged with customer service were eventually able to get parts replaced, though it sometimes required persistence.
How Does the THERUN Compare to Other Popular Models?
The THERUN Folding Incline Treadmill 3.5 HP occupies a competitive space. While it excels in power and incline, different users have different needs. Here’s a look at how it stacks up against some notable alternatives.
1. BORGUSI Folding Treadmill Auto Incline 3.0HP
- 【Widened Double Shock-Absorbing Deck】BORGUSI 43.5" x 17.5" large running track to fit different users‘ stride lengths. The stability of the double...
- 【12% OneTouch Auto Incline & Speed Control】12% auto incline treadmill fully meets your various workout intensity. 3.0HP silent motor supports the max...
The BORGUSI treadmill is a very close competitor to the THERUN, targeting a similar user. It features a slightly less powerful 3.0 HP motor and a lower top speed of 8.5 MPH compared to THERUN’s 10 MPH. However, it counters with a slightly wider 17.5-inch tread belt. For users who prioritize a bit more side-to-side room over top-end sprinting speed, the BORGUSI could be an attractive option. Both offer auto incline and a 300 lb capacity, but the THERUN’s more powerful motor gives it an edge for those who plan on doing more intense running and interval training.
2. WALKINGPAD Foldable Walking Pad Treadmill

The WALKINGPAD represents a different category of machine altogether. It is not designed for running. This is an ultra-compact, no-assembly-required walking pad built for under-desk use in an office or for walking in a small apartment. It lacks an incline feature and has a much lower top speed. For individuals whose sole goal is to increase their daily step count while working or watching TV, and who have no intention of jogging or running, the WALKINGPAD’s minimalist design and extreme portability make it a superior choice. It is not, however, a substitute for a full-featured treadmill like the THERUN.
3. Lichico Walking Pad Under Desk Treadmill
- 【Whisper-Quiet Operation】Utilizing 2.5HP brushless motor, our walking pad runs super quietly, ensuring no disturbance to others. Say goodbye to...
- 【Dual Shock Absorption】 Equipped with both suspended shock-absorbing deck and high-performance TPR cushioning pad, the walking pad treadmill...
Similar to the WALKINGPAD, the Lichico model is a dedicated walking and light jogging machine. It emphasizes its super quiet brushless motor, making it ideal for office environments where noise is a primary concern. It is portable, small, and designed for convenience. If your fitness needs are met by walking and you value a machine that is as unobtrusive as possible, the Lichico is a strong contender. However, it lacks the power, speed, incline, and robust frame of the THERUN, making it unsuitable for anyone looking for a challenging running or hill-climbing workout.
Final Verdict: Is the THERUN Folding Incline Treadmill 3.5 HP the Right Choice for Your Home Gym?
After extensive testing and analysis, our verdict is clear: the THERUN Folding Incline Treadmill 3.5 HP is an outstanding value and one of the best home treadmills we’ve seen in its price class. It punches well above its weight, delivering core features like a powerful 3.5 HP motor and a challenging 15% auto incline that are typically reserved for more expensive models. It masterfully balances performance with practical home-use features like a sturdy, foldable frame and an intuitive interface.
This treadmill is the perfect choice for beginners, intermediate runners, and anyone looking to simulate hiking or add high-intensity intervals to their routine. It provides the stability, power, and versatility needed to grow with you on your fitness journey. While it may be too heavy for some to move easily and lacks the giant touchscreen of premium “smart” treadmills, it focuses its budget on what matters most: a fantastic workout experience. For the price, you will be hard-pressed to find a more capable and reliable machine.
