TreadmillReviewGuru gave the NordicTrack 2450 their top pick two years running, and the reasons are measurable. In their motor responsiveness test, timing acceleration from 1 mph to 14 mph, the 2450 finished six seconds faster than every other treadmill in the lab, including the Peloton Tread and the Horizon 7.0 AT. Connect The Watts confirmed it: the 4.25 CHP motor paired with SmartAdjust auto-incline makes interval workouts feel effortless because the belt keeps up with you instead of lagging behind.
The cushioning sealed it. TreadmillReviewGuru stated flatly that unless you spend $10,000 on a commercial machine, you cannot find a softer running deck. Connect The Watts described the shock absorption as "highly springy, forgiving, and great for longer distances." For runners logging 20+ miles a week, that kind of joint protection compounds over months.
The 24-inch rotating touchscreen adds genuine utility beyond gimmick status. You can stream Netflix or Spotify while iFIT's SmartAdjust continues adjusting incline and decline in the background, mimicking outdoor trail elevation. Connect The Watts highlighted this as a standout: the screen pivots for off-treadmill floor workouts too. At $2,999, you're paying for the fastest motor, the softest deck, and the biggest screen in a package that still folds (if you can deadlift the deck).
What It Won't Do
The 2450 removed all physical speed and incline buttons. Connect The Watts hammered this point: trying to swipe a touchscreen at 12 mph is harder than twisting a dial. TreadmillReviewGuru also flagged screen glare from overhead lighting during iFIT's dark-mode interface. And folding? The deck feels like lifting 40 to 50 lbs. Connect The Watts tested the new folding mechanism and warned it drops hard and fast if you don't control it carefully. This is not a treadmill you'll casually fold up after every session.
TreadmillReviewGuru called the Horizon 7.0 AT "truly one of the best value deals you can get on a running treadmill," and the numbers back it up. At $999, you get a 3.0 CHP motor that Foremost Picks praised for its "rapid sync" responsiveness, a 15% maximum incline (three percentage points steeper than the $2,999 NordicTrack 2450), and a 20 x 60-inch running deck that fits tall runners.
The real win is what you don't pay. Zero subscription. Zero monthly fees. The 7.0 AT ships with 8 built-in programs and Bluetooth connectivity to Peloton, Zwift, Apple GymKit, and other third-party apps. TreadmillReviewGuru emphasized this: bring your own tablet, run your own apps, and keep your wallet closed.
Horizon's 3-zone variable cushioning system splits the deck into a soft landing zone at the front and a firm push-off zone at the back. TreadmillReviewGuru ranked Horizon as the second most cushioned brand behind NordicTrack. And the warranty? Lifetime frame, lifetime motor, 3 years parts. At $999, that warranty alone would justify consideration.
What It Won't Do
The 7.0 AT has no touchscreen. You get a 7.25-inch LED display with basic workout data, and that's it. If you want instructor-led classes or scenic runs, you're propping your own tablet on the holder. The deck is also 2 inches narrower than the premium standard (20 inches versus 22), which wider-stanced runners will notice. And there's no decline: the 7.0 AT is incline-only, so downhill training requires a different machine.
