Choose the COROS PACE 4 if low weight and longer manufacturer-rated battery life matter most. Choose the Garmin Forerunner 265 if you’ll use Garmin’s Training Readiness, adaptive daily suggested workouts, downloadable streaming music or Garmin Pay. Both are capable AMOLED running watches with route guidance; neither is the universal winner.

Battery numbers are manufacturer maximum estimates, not guarantees or results from a shared test. Garmin’s figures are for the 46 mm Forerunner 265; the smaller 265S has different specifications. COROS lists the PACE 4’s modes and estimates, while Garmin’s Singapore specification page gives the 46 mm model’s figures.

Which watch is better for your priorities?
Choose the COROS PACE 4 for a lighter watch and less frequent charging
At 32 g with its nylon band, the PACE 4 is substantially lighter than the 47 g 46 mm Forerunner 265. Even with its silicone band, COROS lists it at 40 g. If you notice a watch on your wrist during long runs, or simply want less weight for everyday wear, that difference may matter.

COROS also claims up to 41 hours in All-Systems GPS mode and up to 19 days of daily use. Those are the manufacturer’s maximum estimates; settings and feature use affect actual battery life. The PACE 4 is the more compelling fit if you prioritize a light build, fewer charging stops and a focused set of running tools over Garmin-specific smart features.
#1 Best Overall

Choose the Forerunner 265 for Garmin’s training and connected features
Garmin’s strongest case is the connected training experience: Training Readiness, adaptive daily suggested workouts, Morning Report, training effect and acute load. If you already use Garmin’s training ecosystem—or know you’ll act on its readiness and workout suggestions—the 265 offers tools the PACE 4 does not match feature for feature.
The 265 also supports downloads from streaming services such as Spotify and offers Garmin Pay. These can make it more useful for phone-free runs and daily errands. Check that your preferred music service and payment setup are supported in your country before buying.
Rank #2
- Uncompromisingly light and durable: The 6000‑series aluminum alloy bezel provides a high‑integrity frame, yet PACE 4 Black Crystal weighs just 33 g (with nylon band) – balancing structural integrity, a smooth finish, and an incredibly lightweight profile for the wear and tear of an active life.
- AMOLED AT ITS BEST: The touchscreen AMOLED display has a tapered edge, crystal clear visibility, and vibrant colors. It brings a more detailed display with 164% higher resolution than the COROS PACE 3.
- BIG BATTERY LIFE: Train longer without interruption. With 41 hours of continuous GPS use and up to 19 days of daily battery life, ensure your training isn’t tied to a charger.

Training, tracking and navigation
Both watches offer substantial running features. COROS lists Running Fitness, race predictions, personalized marathon plans, Virtual Pacer, and recovery and wellness tools. Garmin adds its own training metrics and daily guidance, including Training Readiness and adaptive suggested workouts. The useful distinction is not whether either watch can support training, but whether Garmin’s particular readiness and workout system is valuable to you.
Both watches have AMOLED touchscreens and advanced satellite positioning. COROS’s PACE 4 has a 1.2-inch AMOLED display, an 11.8 mm case, two buttons and a digital dial. Garmin lists a 1.3-inch, 416 × 416 AMOLED display, touchscreen and buttons, SatIQ and multi-band GPS for the 46 mm 265. Garmin also specifies a 5 ATM water rating for that model.
Rank #3

For navigation, both can guide you along a route with breadcrumb-style directions. COROS says the PACE 4 supports route syncing from COROS and third-party services, as well as off-course alerts, but does not have full maps. Tom’s Guide likewise reports that neither watch in its comparison has full maps. If seeing map detail on your wrist is essential, look beyond these two models.

The PACE 4 stores MP3 files and can control media on a connected phone. COROS’s product FAQ says it does not directly support Spotify or Apple Music. That makes the distinction practical: the PACE 4 can play stored audio, while the Forerunner 265 can download music from supported streaming services. Garmin Pay is another convenience the COROS comparison does not offer. Feature availability and compatibility can vary, so confirm the service and payment support you need in your region.

What one direct comparison found—and what it can’t prove
In a Tom’s Guide comparison that included the author wearing both watches for a half marathon, the reviewer found both capable for core sports tracking, favored Garmin for smart features and Training Readiness, and preferred COROS for battery life and GPS results on the reviewer’s routes. The article also reports that wrist-based optical heart-rate sensors can lag chest straps during changes in effort, and that the reviewer saw more PACE 4 errors than 265 errors in the tested run. These are observations from one reviewer’s use, not a controlled population-level comparison or a guarantee of what every runner will see. Read the Tom’s Guide comparison.
Which Garmin size should you compare?
The 47 g weight and battery estimates above refer to Garmin’s 46 mm Forerunner 265, not the smaller 265S. Tom’s Guide reports different figures for the 265S: up to 15 days in smartwatch mode and up to 15 hours in multi-band GPS mode. If the 46 mm model seems too large, compare the 265S directly and check its current official specifications rather than applying the 265’s figures to it.
Price and final buying checklist
Tom’s Guide listed the PACE 4 at $249 and the Forerunner 265 at a $449 full price with a $299 sale snapshot at review time. These are US review-time prices, not confirmed current prices. Check the live price, region and exact watch variant before purchasing; sales and availability change.
Quick Recap
- Pick the PACE 4 if its lower listed weight and higher manufacturer-rated battery maxima are your priorities.
- Pick the Forerunner 265 if you’ll use Training Readiness, Garmin’s suggested workouts, streaming music downloads or Garmin Pay.
- For route following, both offer breadcrumb guidance; neither provides full maps according to the cited product information and comparison.
- Compare the 265S if you want the smaller Garmin size, and verify which size a listing actually sells.
