What this guide can—and cannot—tell you
These are research-based recommendations, not results from our own treadmill testing. We matched current US models to manufacturer specifications, manuals and purchase destinations. The comparisons explain buying trade-offs; they do not establish measured differences in cushioning, noise, acceleration or durability.
Which treadmill should you buy for running?
Start with how you want to train. An integrated coaching screen is useful only if you intend to use its connected workouts. Physical controls and your own tablet offer a different ownership experience, not necessarily a worse one. Decide which arrangement you would still want after an introductory membership expires.
Three running treadmills compared
1. NordicTrack Commercial 1750: for a larger coaching screen
Larger-screen connected training
NordicTrack Commercial 1750
22 × 60-inch belt · 0–12 mph · -3% to 12% grade · 16-inch pivoting touchscreen · 400 lb stated capacity.[1]
The strongest match here for buyers who specifically want the larger integrated coaching display.
The reason to shortlist the Commercial 1750 is its screen-led training setup, not simply a large motor number. The current NTL17125 combines a 16-inch pivoting display with uphill and downhill settings. The pivoting screen also matters if you intend to follow supported off-treadmill sessions.[1]
It is less persuasive if you will ignore the connected content. Full iFIT content and features require paid iFIT Pro and Wi-Fi; activation requires a free account and agreement to terms. Treat the continuing subscription as part of the purchase, not a small detail after checkout.[1]
Who it suits
Runners who want integrated coaching, a larger display and decline, with a permanent operating space for a full-size treadmill.
Who should skip it
Buyers wanting a simple console, no connected-training commitment or a light machine to move between rooms. Folding does not remove its operating footprint.
Ownership trade-off: NordicTrack's current US page lists lifetime motor, ten-year frame, two-year parts, one-year tablet and one-year labor/repair coverage. Lifetime motor coverage is not lifetime free service. Check the seller and applicable terms.[1]

2. NordicTrack Commercial 1250: the smaller-screen iFIT alternative
Smaller-screen connected training
NordicTrack Commercial 1250
22 × 60-inch belt · 0–12 mph · -3% to 12% grade · 10-inch tilting touchscreen · 400 lb stated capacity.[2]
Compare it when you want iFIT and decline but do not need a larger pivoting screen.
The Commercial 1250 is not merely a smaller treadmill. Its current NTL14125 specification retains the listed belt dimensions and grade range of the Commercial 1750, with the same 77.3 × 37-inch operating footprint. The meaningful differences include its 10-inch tilting screen and shorter stated motor coverage.[1][2]
That makes it a smaller-screen alternative, not an automatic value winner. Compare delivered offers and ownership costs before deciding whether the trade-off makes sense. Both exact-model manuals describe manual speed and incline control, while full connected features remain a separate iFIT membership decision.[2][6][7]
Who it suits
Buyers who specifically want iFIT-led running and downhill settings, find a 10-inch display adequate, and accept the current warranty.
Who should skip it
Anyone expecting the larger model's pivoting screen or lifetime motor term. It is also not the answer to a genuinely small operating room.
Ownership trade-off: the current US product page specifies two-year motor coverage, not the 1750's lifetime motor term. The linked Amazon bundle includes one month of iFIT Pro; check introductory eligibility, renewal, seller and delivery arrangements.[1][2][8]

3. Horizon 7.4 AT: physical controls and your own screen
Physical controls; bring your own screen
Horizon 7.4 AT
22 × 60-inch belt · 0.5–12 mph · 0–15% incline · conventional LCD and LED display · 350 lb stated capacity.[3][4]
For runners who would rather choose their own training content than buy an integrated touchscreen platform.
The Horizon 7.4 AT combines physical QuickDial speed and incline controls with a conventional display and room for your own device. The current official US retail SKU is HTM1380-01. Our purchase button goes to Horizon's store because the Amazon listing we reconciled identified older stock, not that current SKU.[3][4]
For intervals, consider the controls alongside maximum speed. We have not timed acceleration, so QuickDial and RapidSync are not evidence of a measured advantage. The incline range also starts at zero: choose another option here if downhill settings are important.[3]
Who it suits
Runners who prefer physical adjustments, already have a tablet or television setup, and want to choose optional training apps separately.
Who should skip it
Buyers wanting decline, an integrated coaching touchscreen or frequent relocation. Horizon lists 318 lb machine weight and 42 × 37 × 71-inch folded dimensions.[4]
Ownership trade-off: Horizon lists lifetime frame and motor coverage, five years for parts and two for labor. Confirm local service coverage and the delivered generation's app compatibility. Its store was accepting orders with an estimated ship week of November 2, 2026 when checked; confirm the current dispatch estimate and address eligibility before paying.[3][5]

What should heavier runners look for?
Compare stated capacity with the whole ownership package. NordicTrack lists 400 lb for the documented Commercial 1750 and Commercial 1250; Horizon lists 350 lb for the 7.4 AT. These are manufacturer limits, not our evidence of stability, belt behavior or durability under a particular running load. Do not exceed the applicable limit.[1][2][3]
If you are close to a model's limit, ask the manufacturer specifically about your intended running frequency and pace. Compare deck dimensions, control reach, warranty exclusions, service access and returns as well as the capacity number. We do not invent a percentage of spare capacity or award a heavier-runner winner from that number alone.
What matters for taller runners and intervals?
All three choices list a 60-inch-long, 22-inch-wide running surface. That is a useful starting point, not a universal height or stride guarantee. Try the exact model at your intended pace if possible, and account for overhead clearance at your highest intended incline.[1][2][3]
For intervals, check how you will change pace and grade while maintaining your running position. A 12 mph specification says nothing about time to reach that speed. Compare physical controls, on-screen adjustments and app dependency. NordicTrack also explains that CHP is a laboratory comparison rating, not household operational horsepower.[1][2]
Will a running treadmill fit your home?
Measure the operating space and access route before comparing folded storage. The 1250's US manuals require at least eight feet behind and two feet at each side, additional to its footprint. Apply the supplied instructions for your exact machine rather than transferring one brand's clearance rule to every treadmill.[6][7]
Check doors, staircases, turning space, ceiling height and electrical requirements. Confirm whether delivery includes stairs, placement, assembly and packaging removal. Folding helps storage between sessions; it does not make a heavy running treadmill portable or remove its operating-space requirements.
If folded storage is the priority, compare our best folding treadmills. For desk walking rather than running, use the walking-pad guide. Our overall treadmill guide covers the broader choice.
How we selected these running treadmills
We prioritized full-size running surfaces, clear US model documentation, meaningful differences in training setup and identifiable purchase routes. We compared manufacturer specifications, manuals and warranties, and checked Amazon model identity separately. Fit recommendations are editorial judgments, not hands-on ratings. Walking-only machines and unresolved current-model purchase matches were left out.
Frequently asked questions
Which treadmill would you choose for guided running?
The Commercial 1750 is our first shortlist if you want a 16-inch pivoting coaching screen with incline and decline. Its full connected experience requires paid iFIT Pro and Wi-Fi.[1]
Is the Commercial 1250 just a cheaper 1750?
Compare more than price. The 1250 has a smaller tilting display and different motor coverage. Its listed operating footprint is still the same 77.3 × 37 inches as the 1750.[1][2]
Which option avoids a required training subscription?
The Horizon 7.4 AT supports standalone training; optional apps are separate. The 1250's manuals also describe manual mode, but full NordicTrack connected features require paid Pro and Wi-Fi.[2][3][6][7]
Are these suitable for heavier runners?
The two NordicTrack models have stated 400 lb limits; the Horizon limit is 350 lb. Stay within the limit and assess your running use, room, controls and service support. Capacity is not a tested guarantee of comfort or durability.[1][2][3]
Can a folding walking pad replace a running treadmill?
Not if the model is walking-only. Match the treadmill to its stated use rather than its folding mechanism. Our walking-pad guide separates desk-walking needs from the running brief here.
Why does the Horizon button go to its manufacturer?
The current official US Horizon 7.4 AT is SKU HTM1380-01. We did not establish an exact-current Amazon match, so the button goes to the official store rather than a similarly named older listing.[3]
