JTX Fitness Review
The JTX RunRise XL is the larger, more powerful version of the RunRise: a 2.25 CHP brushless motor, 12.4 mph top speed, a roomier 150 by 50 cm deck and a 135 kg user limit, on a deck that still folds flat. It is the flat-fold JTX for people who want to run properly, at £999 or £949.05 with our discount code. Here is our full assessment.

What is the JTX RunRise XL?
The RunRise XL is the larger sibling of the RunRise, built for people who want a flat-folding treadmill they can actually run on rather than just jog. It keeps the flat fold, the 16-inch screen and the Kinomap and Zwift connectivity, but steps up the motor, speed, deck size and user limit across the board.
At £999, or £949.05 with our HOMETREADMILL5 code at the checkout, it sits between the standard RunRise and the hydraulic-fold Sprint-7. The code works across the JTX treadmill range but does not apply to refurbished machines. The XL is the flat-fold option for runners, where the Sprint range trades the flat fold for a sturdier hydraulic frame.
Motor and running feel
The 2.25 CHP brushless motor is a meaningful step up from the RunRise’s 1.5 CHP, giving more headroom for sustained running and a 12.4 mph (20 km/h) top speed that covers genuine running rather than just jogging. As a brushless unit it stays relatively quiet and cool, and is built to handle regular use without the wear of a brushed motor.
On a flat-folding frame at 75 kg it is naturally a touch less planted than a heavy fixed-frame machine, but within its class it feels stable and capable, and the larger deck helps at speed.
Deck, cushioning and incline
The running surface grows to 150 by 50 cm, longer and wider than the RunRise’s 130 by 45 cm, which makes a real difference for taller runners and anyone with a longer stride. A 6-point cushioning system takes the edge off the impact, and the user limit rises to 135 kg, the highest of the flat-fold JTX models.
Incline stays at 10 percent power, the same as the standard RunRise, and auto-adjusts on Kinomap routes. If maximum gradient matters to you, the Sprint models offer 12 percent, which also puts the 12-3-30 protocol out of reach here, but for most training 10 percent is plenty.
Screen, apps and connectivity
Like the RunRise, the XL has a 16-inch screen and connects over Bluetooth to both Kinomap and Zwift, with built-in speakers and Polar-compatible heart-rate support. Kinomap drives the auto-incline to match the route; Zwift handles group runs and structured plans. Both have free tiers, so there is no mandatory subscription, which keeps the running cost down against iFIT-locked rivals.
Folding, footprint and delivery
The XL folds flat to around 25 cm for under-bed or upright storage, the same trick as the RunRise, and rolls on transport wheels. In use it takes up roughly 172 by 78 cm. At 75 kg it arrives fully assembled, so there is no build on delivery, though note JTX delivers this model to the ground floor only, so plan for getting it to its final room yourself if you are upstairs.
How it compares
Against the standard RunRise at £799, the XL is the better runner: more motor, more speed, more deck and a higher weight limit, for £200 more, or £190 more once the code is applied to both. Against the Sprint-7 at £1,149, the trade is the fold type: the XL folds flat for under-bed storage, while the Sprint-7 uses a sturdier hydraulic fold-up deck, adds a 12 percent incline and a 3-year warranty, but cannot be stored flat. Choose the XL if flat storage and a brushless motor matter most; choose the Sprint-7 if you want the hydraulic frame and more incline. Our best folding treadmills guide widens the field.
Where JTX stands in 2026
A quick note for 2026 buyers: JTX has refreshed its branding this year around being an independent UK maker that sells direct with no subscriptions. On the RunRise XL that means the Kinomap and Zwift connectivity it relies on runs on free tiers, so the connected running it is built for costs nothing extra to use, unlike the iFIT-tied machines in the same bracket.
Our overall RunRank is a weighted view across the four pillars, not a flat average. The bigger deck, brushless motor and dual-app support make it a capable flat-fold runner, and the free-tier connectivity keeps the real cost of ownership down; the 10 percent incline ceiling and the inherent give of a flat-folding frame are what hold it just short of the Sprint range. How RunRank works.

Should I buy the RunRise XL or the Sprint-7?
The XL folds flat, uses a brushless motor and costs £999; the Sprint-7 is £1,149 and has a sturdier hydraulic fold, a 12 percent incline and a 3-year warranty but cannot be stored flat. Choose on whether flat storage or the hydraulic frame and extra incline matter more.
The verdict
The RunRise XL is the flat-fold JTX for people who want to run, not just jog. The 2.25 CHP brushless motor, 12.4 mph top speed, roomy 150 by 50 cm deck and 135 kg limit make it a genuinely capable runner that still slides under a bed, and the free-tier Kinomap and Zwift support keeps it cheap to live with. The 10 percent incline and 2-year warranty are the only things that trail the Sprint range. If flat storage is a priority and you want more than the standard RunRise offers, at £949.05 with our code it is the pick.
