For years the GPS watch question had one answer: buy a Garmin. That’s no longer automatic. COROS has spent the last few years undercutting Garmin on price while beating it on battery life, and 2026 pushed the gap further — the new COROS Pace 4 Pro (launched September 22) brings a titanium and sapphire build, offline maps, and a speaker to a $449 watch, and a September firmware update added maps to the $249 Pace 4.
Garmin still has real advantages, though, and most of them are in software rather than hardware. Here’s how the two brands actually compare in 2026, matched up price tier by price tier. Prices below were checked in late September 2026.
The Short Answer
Choose COROS if you want the most hardware for your money: longer battery life, offline maps at every price point, and premium materials for hundreds less than Garmin charges. COROS’s training analytics (EvoLab) are free, and it syncs with Strava, TrainingPeaks, Zwift, and most other major platforms.
Choose Garmin if you want the deeper ecosystem: contactless payments, downloadable Spotify and other streaming playlists (on the 570 and 970), adaptive Garmin Coach training plans, the Connect IQ app store, ANT+ sensor support, and more detailed readiness and recovery analysis. Garmin’s flagship also has routable maps and a real LED flashlight.

Entry Level: Forerunner 70 / 170 vs. COROS Pace 4
At $249, the Pace 4 is the same price as Garmin’s Forerunner 70 and $51 less than the Forerunner 170 — and on paper it gives you more than either. You get a 1.2″ AMOLED screen in a roughly 40-gram watch, up to 19 days of smartwatch battery, about 31 hours of dual-frequency GPS, wrist-based running power, triathlon and open-water swim modes, and (since a September 2026 update) basic offline maps. Neither Garmin at this tier has multi-band GPS or maps, and the Forerunner 70 also skips the altimeter and open-water swim tracking.
What the Forerunner 170 gives back is Garmin Pay, Garmin’s training software (the same Training Readiness and HRV Status found on its pricier watches), and ANT+ support for power meters and smart trainers.
Our take: For a new runner or triathlete on a budget, the Pace 4 is the better-equipped watch. Pick the Forerunner 170 if you want to pay with your watch or you’re already invested in Garmin Connect.

Mid-Range: Forerunner 570 vs. COROS Pace 4 Pro
This is the matchup most triathletes should care about. Both are full multisport watches with AMOLED screens, speakers, and microphones. The Pace 4 Pro is $100 cheaper and still comes out ahead on hardware: a titanium bezel and sapphire lens (in the Forerunner line, Garmin reserves both for the $750 Forerunner 970), offline maps with street and trail names, and two to three times the multi-band GPS battery life, depending on display settings. On a full-distance triathlon, that’s the difference between finishing with charge to spare and managing your battery.
The Forerunner 570 answers with software and smart features: Garmin Pay, downloadable playlists from Spotify and other services (COROS only plays MP3 files you load yourself), adaptive training plans, and Garmin’s more detailed readiness and recovery tracking. It also supports ANT+ sensors, which matters if you train with an older ANT+-only power meter; the Pace 4 Pro connects to sensors over Bluetooth.
Our take: The Pace 4 Pro is the better value and the better long-course race watch. The 570 is the better everyday smartwatch and training coach.

Flagship: Forerunner 970 vs. COROS Pace 4 Pro
Tom’s Guide found the Pace 4 Pro matched the Forerunner 970 for GPS accuracy while beating it on battery life — at $300 less. The 970 still justifies its price for some athletes: its maps can route and reroute you on the watch (COROS maps can’t), it has a real LED flashlight for pre-dawn runs and dark transition areas, and it offers ECG and skin temperature tracking alongside Garmin’s full training suite.
Our take: If you’ll use turn-by-turn navigation or the flashlight, get the 970. If you mostly want a premium, long-lasting race watch, the Pace 4 Pro gets you most of the way for much less.

What About the COROS Apex 4 and Vertix 2S?
Both are built more for trail and mountain use than road racing. They use MIP (memory-in-pixel) screens instead of AMOLED, which look less vivid but stretch battery life dramatically. The Apex 4 ($429 for 42mm, $479 for 46mm) adds a titanium bezel, sapphire lens, maps, and music with up to 24 days of smartwatch battery on the larger size. The Vertix 2S ($699) is COROS’s battery king at up to 40 days, but it launched in 2024 and a successor has already turned up in regulatory filings, so we’d hold off unless you find it discounted.

Software and Ecosystem: Where Garmin Still Leads
Garmin’s advantages: Garmin Pay contactless payments (Forerunner 170 and up), streaming-service music downloads (570 and 970), free adaptive Garmin Coach training plans, the Connect IQ store for third-party apps and watch faces, ANT+ sensor support, and more detailed daily readiness guidance.
COROS’s advantages: EvoLab training metrics (training load, recovery, race predictions, VO2 max, threshold pace) are free on every watch, and COROS connects with more than 50 third-party apps including Strava, TrainingPeaks, Zwift, Runna, and Wahoo. Switching is easy, too: COROS can import your workout history from Garmin.
What COROS doesn’t have: contactless payments, streaming-service music, an app store, or on-watch route planning. If any of those are dealbreakers, stick with Garmin.
A Note on Discounted Older COROS Watches
You’ll see older COROS models like the Pace 3 and Pace Pro heavily discounted right now. They’re not bad watches, but check before you buy: reviewers have reported that the Pace Pro is no longer receiving firmware updates, so it won’t get new features like the maps just added to the Pace 4. At similar prices, the current models are the safer buy.
Which Should You Buy?
- Best budget watch for runners and triathletes: COROS Pace 4
- Budget, but you want Garmin Pay and Garmin Connect: Garmin Forerunner 170
- Best value triathlon watch: COROS Pace 4 Pro
- Best everyday smartwatch that’s also a tri watch: Garmin Forerunner 570
- Want navigation, a flashlight, and every feature: Garmin Forerunner 970
- Trail and mountain athletes: COROS Apex 4
The Bottom Line
In 2026, COROS wins on hardware per dollar at nearly every price point, and the Pace 4 Pro in particular makes Garmin’s mid-range look expensive. Garmin wins on everything around the hardware — payments, music, coaching, apps, and sensor compatibility. Decide which side of that trade matters more to you and the choice gets easy.
