Motor: 3.5 CHP Rapid Sync | Speed: 0.5–12 mph | Incline: 0–15% | Deck: 152 × 56 cm (60 × 22 in) | Max user weight: 147 kg | Folding: Yes, hydraulic | Warranty: Lifetime frame & motor | Price: £1,499
The Horizon 7.4 AT is the runner’s pick of the Studio Series. It takes everything that makes the 7.0 AT a great no-subscription treadmill and turns up the parts that matter for serious running: a bigger 3.5 CHP motor, a wider 22-inch deck, the built-in Sprint 8 HIIT programme and an 8.25-inch LCD screen. If you run more than you walk, train for events, or simply want more machine without paying for a locked-in subscription ecosystem, this is the Horizon to look at.
At £1,499 it sits one step above the 7.0 AT (£1,299) and below the trail-focused Paragon X (£1,699). The extra spend over the 7.0 AT is modest, and for anyone running regularly it is money well spent.
Who it’s for: regular runners and joggers, HIIT and Sprint 8 fans, taller or heavier runners who want the wider deck, and anyone who wants a built-in screen and onboard programmes without a monthly fee.
Who it’s not for: walkers and occasional users, who will be better served and save money with the Omega Z or 7.0 AT, and runners specifically chasing trail-terrain simulation, who should look at the Paragon X.

Key Features and Benefits
Motor and Speed
The headline upgrade over the 7.0 AT is the 3.5 CHP motor, half a horsepower more, paired with the same Rapid Sync drive system that responds around 33% faster than conventional treadmill motors. In practice that extra power means the belt holds pace effortlessly during sustained running and hard intervals, runs cooler under load, and should simply last longer thanks to working less hard at any given speed. The 0.5 to 12 mph range matches the 7.0 AT, but the 7.4 AT sustains the top end with more headroom.
Wider 22-inch Deck
The deck grows to 152 by 56 cm (60 by 22 inches), two inches wider than the 7.0 AT. That extra width is the upgrade runners feel most. It removes the slight need to stay perfectly centred at speed, giving you room to open up your stride and relax your form during fast intervals and longer sessions. Combined with the full 60-inch length, it is a genuinely spacious running surface that suits taller and heavier runners well.
Incline and Sprint 8 HIIT
You get the same steep 0 to 15% power incline as the 7.0 AT, driven by a 500 lb thrust incline motor and adjusted on the fly with the QuickDial control. Where the 7.4 AT pulls ahead is the built-in Sprint 8 programme, a 20-minute high-intensity interval workout designed to maximise fat burn in minimal time. It is one of the few treadmills to bake a structured HIIT protocol into the console itself, so you can run a proven interval session without setting anything up or pairing an app. Pair it with the steep incline for serious hill interval training.
Console and 8.25-inch Screen
Unlike the 7.0 AT’s basic LED, the 7.4 AT adds an 8.25-inch LCD screen alongside a 16-digit LED readout. It is not a streaming touchscreen in the NordicTrack sense, but it gives you a clearer, richer display of your workout data and Sprint 8 guidance. The QuickDial speed and incline controls return, letting you adjust both without breaking stride, and there is a cooling fan, Bluetooth speakers, a tablet holder and USB charging. Crucially, the screen enhances the experience without tying you to any subscription.
Open Platform and Connectivity
Like the rest of the range, the 7.4 AT is open platform. It connects over Bluetooth to apps such as Peloton, Zwift and Studio, and a Bluetooth heart-rate chest strap is included in the box. The apps display your metrics and guide your session, though as with most non-FTMS Horizon models they prompt rather than auto-adjust your speed and incline. The point stands: you bring your own apps and devices, and nothing essential is locked behind a fee tied to the machine. Compare that with an iFIT-locked NordicTrack.
Folding, Footprint and Warranty
The 7.4 AT uses the same one-step hydraulic folding as its siblings and rolls on transport wheels, though at around 144 kg it is a substantial machine, heavier than the 7.0 AT thanks to its beefier motor and frame. As with any 15% incline treadmill, allow extra ceiling clearance at full gradient. The warranty is excellent: lifetime frame and lifetime motor, plus 5 years parts and 2 years labour, among the strongest cover at this price. UK terms can vary slightly by retailer, so confirm at checkout.

How the Horizon 7.4 AT Compares
vs Horizon 7.0 AT (£1,299): The 7.4 AT adds a bigger 3.5 CHP motor, a wider 22-inch deck, Sprint 8 HIIT, an 8.25-inch LCD and a cooling fan for about £200 more. If you run regularly or train hard, that upgrade is well worth it. If you mix walking and running, the 7.0 AT is the smarter spend.
vs Horizon Paragon X (£1,699): The Paragon X costs £200 more again and adds AirTrain terrain simulation and a higher 180 kg user capacity, aimed at trail and event runners. The 7.4 AT is the better straight-line running value; the Paragon X is for those who want the immersive trail feel.
vs NordicTrack at this price: A similarly priced NordicTrack gives you a large streaming touchscreen and iFIT classes, but the best of it depends on a subscription. The 7.4 AT trades the big screen for stronger no-subscription running hardware and a lifetime warranty. Choose based on whether you want guided classes or subscription-free freedom.
Verdict
The Horizon 7.4 AT is the best Horizon treadmill for people who run. The 3.5 CHP motor, wider 22-inch deck, built-in Sprint 8 HIIT and lifetime frame and motor warranty add up to a serious running machine that still refuses to lock you into a subscription. It is heavier and more than a walker needs, but for regular runners and HIIT fans who want room to push and hardware that lasts, the modest premium over the 7.0 AT is easy to justify.
