How these alternatives compare to THERUN
MERACH 18% Incline Folding Treadmill
The MERACH T31B1 supports up to 350 lbs, which is 50 lbs more than the THERUN. This makes it a safer choice for heavier users. It offers 18% auto incline, slightly less than the THERUN’s 20%, but still provides strong hill training. The running belt is smaller at 47 by 18 inches. You lose the large running surface and app connectivity found on the THERUN. The motor is also 3.5 HP, matching the original. If you prioritize stability and weight capacity over a wide belt and smart features, this is a strong alternative.
JELENS 15% Auto Incline Folding Treadmill
The JELENS model is much lighter at 79.8 pounds compared to the THERUN’s 158 pounds. It is designed primarily for walking, not running. The motor is weaker at 3.0 HP, and the max speed is lower. It offers 15% auto incline, which is 5% less than the THERUN. The running belt is narrower at 23.2 inches wide. You give up the large 55-inch belt and high-speed capability. However, it includes app compatibility and a heart rate monitor. If you are a walker who needs a compact, budget-friendly option with incline variety, this fits your needs better.
THERUN Folding Incline Treadmill
The THERUN TR04 shares the same 300 lbs weight capacity and 3.5 HP motor as the original. It offers 15% auto incline, which is 5% less than the 20% on the T15. The running belt is significantly smaller, measuring only 47 by 18 inches. You lose the large 55-inch running surface that accommodates tall runners. It lacks the app connectivity and LED lights found on the T15. However, it includes a heart rate monitor. If you want a THERUN product but need a smaller footprint and do not need the steepest incline or smart features, this is a practical choice.
TREAFLOW Folding Treadmill with 25% Auto Incline
The TREAFLOW 7210 offers a 25% auto incline, which is 5% steeper than the THERUN. This provides the most intense hill training in this group. The motor is 3.5 HP, matching the original. However, it lacks app connectivity and has a smaller running belt. The dimensions are 58.3 by 28.7 inches. You give up the large 55-inch belt and smart features for a steeper incline angle. If your primary goal is steep hill training and you do not need a wide belt or app integration, this model focuses on intensity over versatility.
BORGUSI 3.5 HP Auto Incline Folding Treadmill
The BORGUSI treadmill is lighter at 111 pounds, making it easier to move than the 158-pound THERUN. It offers 3.5 HP power, matching the original. However, it lacks app connectivity and has a smaller running surface. The width is 26.2 inches, narrower than the THERUN’s 20-inch belt length but with a different footprint. You lose the large 55-inch belt and smart features. It is designed for moderate incline walking. If you live in an apartment and need a space-saving option with moderate incline but do not need high speeds or app sync, this is a suitable alternative.
Rayspace 3.5 HP Auto Incline Walking Pad
The Rayspace D1 supports up to 450 lbs, which is 150 lbs more than the THERUN. This makes it ideal for very heavy users. It is a walking pad with a 48.2-inch length and 23-inch width, much smaller than the THERUN’s large belt. The motor is 3.5 HP. It includes Bluetooth connectivity and built-in speakers.
