If you’re researching Horizon treadmills, the first thing to know is that Horizon doesn’t make one treadmill for everyone — they make five very different machines for five very different buyers. With 24 years of running and 253 machines tested, I can tell you that choosing the wrong Horizon model is one of the most common mistakes buyers in this range make. This guide cuts through the confusion: here is what each model is built for, who it suits, and who should look elsewhere.
Quick Answer: Horizon makes two product lines — the Go Series (T101, T202) for walkers and casual joggers, and the Studio Series (7.0 AT, 7.4 AT, 7.8 AT) for joggers and serious runners. Every model has Bluetooth FTMS for Zwift, Kinomap, and Peloton — no subscription required. The 7.0 AT is the best-value entry point for runners. The 7.4 AT is the most popular mid-range choice. The 7.8 AT is built for high-mileage runners and heavier users. If you walk primarily, the T202 is the better-value Go Series pick over the T101.
Table of Contents
| Model | Best For | Belt Size | Speed | Incline | Max Weight | Parts Warranty |
|---|---|---|---|---|---|---|
| T101 Connect | Walkers, beginners | 20″ × 55″ | 0.5–10 MPH | 0–10% | 300 lbs | 1 year |
| T202 | Walkers, light joggers | 20″ × 60″ | 0.5–12 MPH | 0–12% | 325 lbs | 1 year |
| 7.0 AT | Joggers, moderate runners | 20″ × 60″ | 0.5–12 MPH | 0–15% | 325 lbs | 3 years |
| 7.4 AT | Runners, interval training | 22″ × 60″ | 0.5–12 MPH | 0–15% | 350 lbs | 5 years |
| 7.8 AT | Serious runners, heavy users | 22″ × 60″ | 0.5–12 MPH | 0–15% | 375 lbs | 5 years |
All five models carry a lifetime frame and motor warranty — one of the strongest base warranties in home treadmills. The key differences between models are belt size, weight capacity, deck thickness, roller size, and how long the parts and labor warranties extend.
What Every Horizon Treadmill Has in Common
Before getting into individual models, it helps to understand what Horizon builds into every machine across the range. Every Horizon treadmill uses Bluetooth FTMS — the open standard that connects to Peloton, Zwift, Kinomap, Strava, and other fitness apps in real time without a proprietary subscription. You bring your own apps; Horizon supplies the machine. This approach is the most important thing that separates Horizon from NordicTrack and ProForm, which lock their best interactive features behind iFit subscriptions.
Every model also uses Horizon’s 3-Zone Variable Response Cushioning — a deck system that provides softer cushioning under foot impact and firmer support at push-off, mimicking the flex pattern of a running shoe. Research published through the NIH links reduced impact loading during running with lower rates of knee and hip stress injury — Horizon’s cushioning system is one of the better implementations of this principle at this price range. Every model folds via the FeatherLight hydraulic system, which does most of the heavy lifting. And every model carries a lifetime frame and motor warranty as a baseline — the parts and labor coverage is where the models diverge.
Go Series: Built for Walkers and Casual Joggers
The Go Series — currently the T101 Connect and T202 — is designed for straightforward walking and light jogging workouts. The machines are lighter, simpler, and more affordable than the Studio Series. They have smaller rollers (46mm/42mm tapered on the T101, 60mm/42mm on the T202), thinner decks (18mm), and shorter parts warranties (1 year). They connect to Peloton, Zwift, and other apps via Bluetooth FTMS, but they lack the QuickDial controls and RapidSync motor technology that makes the Studio Series genuinely useful for interval training.
If your workout is primarily walking, low-intensity jogging, or light cardio a few times per week, the Go Series delivers everything you need without paying for features you won’t use. If you run regularly above 6–7 MPH or want to do structured interval training with app integration, the Go Series will feel limited — move to the Studio Series instead. Our best treadmills for walking guide covers the T101 and T202 alongside other walking-focused machines if you want a direct comparison at that level.
Horizon T101 Connect — Best For: First-Time Treadmill Buyers Who Walk
The T101 is Horizon’s entry point and has been their best-selling model for years. The 20″ × 55″ belt and 10 MPH top speed make it appropriate for walking and light jogging. Its 300 lb weight capacity is the lowest in Horizon’s range. The console is simple — 4 LED windows, 6 built-in programs — but it connects to Peloton, Zwift, JRNY, and Kinomap via Bluetooth FTMS, which is impressive for a machine at this price.
One important note: the T101 is currently sold out on Horizon’s website. Check Amazon for current availability before committing. If it is not available, the T202 is the better choice regardless — the spec upgrade is meaningful for only a modest price difference.
Horizon T202 — Best For: Walkers and Light Joggers Who Want More Room
The T202 is the more capable Go Series machine. It upgrades to a 20″ × 60″ belt (matching the Studio Series entry model), 12 MPH top speed, 12% incline, 325 lb weight capacity, and a larger 60mm front roller that reduces belt friction and extends belt life. It adds a 5″ LCD screen alongside the LED windows and includes a fan — absent on the T101.
For walkers who want a longer running surface and more incline range, the T202 is the better investment over the T101. The parts warranty remains 1 year on both, so the upgrade is purely about physical performance rather than long-term coverage. If you’re jogging regularly above 8 MPH or intend to do structured training, step up to the 7.0 AT instead — the motor and control system difference is significant.
Studio Series: Built for Runners and Interval Training
The Studio Series — 7.0 AT, 7.4 AT, and 7.8 AT — is a genuinely different product tier from the Go Series, not just a more expensive version of the same machine. The key distinctions are the RapidSync motor (designed for fast interval speed changes), QuickDial controls on the handlebars (roll to change speed and incline without breaking stride), and meaningfully longer parts and labor warranties. These machines are built for runners who train with Peloton, Zwift, or other streaming platforms and need a treadmill that responds instantly during interval sessions. For a closer look at how these compare to similar machines from other brands, our best treadmills for runners guide covers the full competitive field.
Horizon 7.0 AT — Best For: Joggers and Moderate Runners Who Want App Connectivity
The 7.0 AT is the entry point to the Studio Series and the best-value Horizon treadmill for anyone who runs regularly. The 20″ × 60″ deck, 15% incline, RapidSync motor, and QuickDial controls give you everything needed for structured interval training with Peloton or Zwift. It’s the only Horizon treadmill that connects to Apple Watch and Samsung Galaxy Watch directly.
Weight capacity is 325 lbs — the same as the T202 — and the deck is 18mm thick. The parts warranty jumps to 3 years over the Go Series’ 1 year, reflecting a more durably built machine. At 277 lbs it’s substantially heavier than the Go Series, which contributes to its stability at running speeds. The 7.0 AT is the correct choice for most buyers who want a runner’s treadmill without paying 7.4 AT prices.

Horizon 7.4 AT — Best For: Regular Runners Who Want More Space and a Better Warranty
The 7.4 AT is Horizon’s most popular model for good reason. It upgrades the 7.0 AT in four specific ways that matter for serious runners: the belt widens to 22″ × 60″ (the commercial standard), the deck thickens to 20mm, the weight capacity increases to 350 lbs, and the warranty extends to 5-year parts and 2-year labor. A Bluetooth chest strap heart rate monitor is included — not sold separately as on the 7.0 AT.
The 22″ belt width is the most underrated upgrade in the range. At running speeds above 9–10 MPH, an extra 2 inches of lateral space reduces the mental effort of staying centred on the belt — a real quality-of-life improvement for tall runners or anyone with a wider natural stride. At 318 lbs, the 7.4 AT is also 41 lbs heavier than the 7.0 AT, which improves stability further under hard running. The 5-year parts warranty signals meaningfully more durable construction. Our best treadmill under $1,500 guide covers the 7.0 AT in context with other brands at that price point if you’re still deciding between tiers.
Check Price on Amazon — 7.4 AT
Horizon 7.8 AT — Best For: High-Mileage Runners and Heavier Users
The 7.8 AT is Horizon’s flagship and the machine built for the hardest use. The belt is the same 22″ × 60″ as the 7.4 AT, but the deck is 20mm thick, the frame weighs 330 lbs — the heaviest in the range — and the weight capacity extends to 375 lbs, the highest of any Horizon treadmill. Aluminum side rails replace plastic on the lower models, which reduces noise and vibration at high speeds. The 9.3″ high-contrast color TFT screen is a genuine upgrade over the LCD panels on every other model. Dedicated media controls on the console let you manage your phone or tablet content without reaching for a separate device mid-run.
The Sprint 8 HIIT program is exclusive to the 7.4 AT and 7.8 AT — a pre-built high-intensity interval protocol based on research from Dr. Phil Campbell. For runners who train to performance metrics rather than just distance, this is worth knowing. The 7.8 AT also carries the same 5-year parts and 2-year labor warranty as the 7.4 AT. The primary reasons to choose the 7.8 AT over the 7.4 AT are the higher weight capacity (375 lbs vs 350 lbs), the superior screen, the aluminum rails, and running very frequently, and wanting the most robust machine in the range.

Which Horizon Treadmill Should You Buy? — The Self-Selector
If you walk for fitness and want simple, reliable equipment: T202. Better value than the T101 with a longer belt and bigger rollers for a modest price difference. Check T101 availability on Amazon first if budget is the primary constraint.
If you jog or run and want to stream Peloton or Zwift classes: 7.0 AT. It has everything you need for app-connected training at the most accessible Studio Series price. The Apple Watch connectivity is a bonus if you track with Apple Health.
If you run regularly and want a machine that will last: 7.4 AT. The wider 22″ belt, thicker deck, better warranty, and included heart rate strap make it the best-rounded machine in the range for committed runners. The 5-year parts warranty is the most important spec here.
If you run hard, run often, or weigh over 300 lbs: 7.8 AT. The 375 lb capacity, heavier frame, aluminum rails, and superior screen justify the premium over the 7.4 AT for this specific user profile. For runners looking at the heaviest-duty machines across brands, our best treadmills for heavy people guide puts the 7.8 AT in the broader context of what’s available.
If none of these sound right: The Go Series machines are not wrong buys — they are the right machines for the right buyer. If your usage is walking 3–4 days per week at moderate pace with occasional light jogging, you don’t need a Studio Series machine. The T202 will serve that use case for years without straining.
Horizon’s No-Subscription Approach — What It Actually Means
Every Horizon treadmill uses Bluetooth FTMS — an open standard that transmits your speed and incline data to any compatible fitness app in real time. Peloton, Zwift, Kinomap, Strava, and Apple Health all work with every Horizon model. You use the apps you already subscribe to; Horizon doesn’t charge you for access to their machine’s full functionality.
This is worth understanding clearly because it’s easy to confuse with NordicTrack’s approach, where the machine’s best interactive features require an ongoing iFit subscription. Horizon deliberately built their machines to be app-agnostic. ACSM guidelines consistently show that training adherence improves when people can exercise to content they enjoy — Horizon’s FTMS approach gives you that flexibility without locking you into one ecosystem. Understanding which muscles different incline levels target helps you get more from these app-driven workouts — our muscles involved in treadmill workouts guide explains this in practical terms.
What Customers Say: Amazon Ratings Across the Range
Customer satisfaction data across Horizon’s range is consistently strong. The 7.0 AT carries the most statistically reliable signal — 4.5 stars across approximately 950 Amazon reviews. The overall brand average sits at 4.5 out of 5 stars across the full range. Here is the breakdown by model:
| Model | Amazon Rating | Review Volume | Most Praised | Most Criticised |
|---|---|---|---|---|
| T101 Connect | 4.4–4.5 ★ | High (top-selling model) | Easy setup, quiet motor, great value for walking | Belt short for tall users, basic console |
| T202 | 4.4 ★ | Moderate | Sturdy build, larger deck, easy folding | Heavier than expected, basic console |
| 7.0 AT | 4.5 ★ | ~950 reviews | Quiet motor, fast incline changes, Apple Watch sync, great for Peloton/Zwift | No touchscreen, modest fan airflow |
| 7.4 AT | 4.4–4.5 ★ | Good volume | 22″ deck width, QuickDial controls, fast incline response, Sprint 8 program | Heavy to move, no built-in screen |
| 7.8 AT | 4.9 ★ (Horizon site) | Low (17 reviews) | Quietest in range, aluminum rails, best screen, very sturdy | Premium price, heavy at 330 lbs |
Two patterns stand out across all models. First, the QuickDial controls and fast incline response on the Studio Series are consistently praised by runners using Peloton and Zwift — the speed at which the machine responds during intervals is a genuine differentiator versus cheaper treadmills with laggy motors. Second, the no-touchscreen design draws occasional criticism from buyers who expected something closer to a NordicTrack, but many positive reviews specifically mention appreciating the simplicity and the absence of a subscription fee.
The 7.8 AT’s 4.9-star rating is exceptional but based on only 17 reviews on Horizon’s own site — treat it as directionally positive rather than statistically definitive. The 7.0 AT’s 4.5 stars across 950 Amazon reviews is the most reliable satisfaction indicator in the range.
Frequently Asked Questions
What is the difference between Horizon Go Series and Studio Series treadmills?
The Go Series (T101, T202) is built for walking and casual jogging — simpler consoles, lighter frames, shorter warranties (1-year parts), and lower price points. The Studio Series (7.0 AT, 7.4 AT, 7.8 AT) is built for runners and interval training — RapidSync motors for fast speed changes, QuickDial handlebar controls, longer warranties (3–5 years parts), heavier frames, and higher weight capacities. Both series have Bluetooth FTMS and no subscription requirement.
Do Horizon treadmills require a subscription?
No. Every Horizon treadmill uses Bluetooth FTMS to connect to third-party apps including Peloton, Zwift, Kinomap, and Strava — none of which require a Horizon subscription. You use your own app accounts. Horizon does not charge any ongoing fee to use their machines’ full connectivity features. This is a deliberate design choice that separates Horizon from subscription-dependent brands.
Which Horizon treadmill is best for runners?
The 7.4 AT is the best choice for most runners. It has a 22″ × 60″ commercial-standard deck, 15% incline, RapidSync motor, QuickDial controls, 350 lb weight capacity, a 5-year parts warranty, and an included chest strap heart rate monitor. The 7.0 AT is the right choice for moderate runners watching budget. The 7.8 AT is the step up for high-mileage runners or users over 300 lbs who want the most robust machine in the range.
What warranty do Horizon treadmills come with?
All Horizon treadmills carry a lifetime frame and motor warranty. Parts and labor warranties differ by model: T101 and T202 — 1 year parts, 1 year labor. 7.0 AT — 3 years parts, 1 year labor. 7.4 AT and 7.8 AT — 5 years parts, 2 years labor. The parts warranty length is a useful signal of build quality — the Studio Series machines are engineered to a more durable standard, which is why Horizon extends coverage further on them.
Does the Horizon 7.4 AT work with Peloton?
Yes. The 7.4 AT uses Bluetooth FTMS, which transmits your live speed and incline data to the Peloton app on your phone or tablet. You follow Peloton classes while running on the 7.4 AT and your metrics sync automatically. The same FTMS connection works with Zwift, Kinomap, Strava, and Apple Health. No Horizon subscription is required for any of this.
Is Horizon a good treadmill brand?
Yes — Horizon is made by Johnson Health Tech, one of the largest fitness equipment manufacturers in the world. Their treadmills are well-regarded for build quality at their price points, particularly the Studio Series. The lifetime frame and motor warranty across the entire range reflects genuine manufacturer confidence. The no-subscription FTMS connectivity approach is one of the most buyer-friendly policies in the category. Their main limitation is that none of their current models have built-in touchscreens — you use your own device on their tablet rack.
What happened to the Horizon T303 treadmill?
The T303 has been discontinued and is no longer part of Horizon’s current lineup. As of 2026, Horizon’s treadmill range consists of five models: T101 Connect and T202 in the Go Series, and 7.0 AT, 7.4 AT, and 7.8 AT in the Studio Series. If you’re looking for a machine in the T303’s former price range, the T202 or 7.0 AT are the current alternatives depending on whether walking or running is your primary use case.
