How long will the Horizon T303 last?

The Horizon T303 treadmill weighs in at 194 lbs. and can hold up to 325 lbs. max weight. It comes with a one-step hydraulic feature to allow for optimal space saving convenience with its folding frame. The T303 has a lifetime warranty on both the frame and motor, 1 year labor, and an upgraded 3-year parts warranty. The T303 was designed to last and will offer moderate users exercise satisfaction for several years. As always, proper care and maintenance will go a long way in extending the life of your investment.

Brief Overview

For less than $1000, the Horizon T303 treadmill comes in as quite a competitor with its upgraded features that will appeal to an eclectic mix of cardio fans. If you intend to go no faster than a light run, the specs on the T303 might meet your requirements for a budget-conscious investment into your fitness future. The console of the T303 is simple like its predecessor but offers convenient custom interval keys to intensify workouts. Another difference is the T303 comes with the ability to wirelessly transmit heart rate data to select apps like Peloton and Zwift.

Overall Quality

The Horizon T303 treadmill offers an easy access to the cardio world of exercise with its quality features and durable frame. The T303 comes with an upgraded 3.0 CHP motor that while powerful, may not hold up to heavy use and it most suited for power walkers to moderate joggers and while it is covered with a lifetime warranty – why invest in a 3.0 when you can shop around and find a 4.0 or higher.
With a 20” x 60” running area, the Horizon T303 is appealing to a varied assortment of users and allows longer strides and better-balanced workouts, mostly in part to not thinking you are going to fall of the treadmill which is possible in the case of smaller running areas. It has a max speed of 12 MPH which will bring most users to a sweat and has an incline of 15% which is more than enough to please all but the hardiest of athletes. The T303 also offers 3 zone cushioning to lesson the impact of strides when exercising. It has a total of 7 built in workouts and offers other such standard features like audio jack, Bluetooth speakers, tablet rack, water bottle holder and fan.
