Is the COROS PACE 3 Worth Buying?
The COROS PACE 3 represents a compelling entry in the mid-range smartwatch market, delivering exceptional value for runners and fitness enthusiasts who prioritize performance tracking over flashy features. After weeks of testing, I can confidently say this watch punches well above its price point, offering capabilities that rival watches costing significantly more. The real question isn’t whether it’s worth buying, but whether its focused feature set aligns with your specific needs.
How Does the COROS PACE 3 Look and Feel?
COROS has maintained a minimalist design philosophy with the PACE 3, and it’s refined to near-perfection. The watch features a 1.3-inch AMOLED display with a crisp 454×454 pixel resolution, delivering vibrant colors and deep blacks that make outdoor visibility excellent even in bright sunlight. The bezel is constructed from stainless steel, while the case comes in your choice of polymer or titanium materials, with the latter adding premium appeal without excessive weight.
At just 38.2 grams, the PACE 3 feels almost weightless on the wrist, making it ideal for extended training sessions. The 46mm case diameter sits at that sweet spot between sporty and dressy—substantial enough to look purposeful yet refined enough for casual wear. The 5 ATM water resistance rating means you can comfortably swim with it, though it’s not rated for diving. Build quality feels solid throughout, with a responsive single crown button and satisfying tactile feedback.
What Health Features Does the COROS PACE 3 Offer?
The PACE 3 integrates a comprehensive suite of health sensors that belie its affordable price tag. The optical heart rate sensor employs COROS’s proprietary algorithm, which has proven remarkably accurate during both steady-state cardio and interval training. The watch also includes a SpO2 sensor for blood oxygen monitoring, an accelerometer for movement tracking, a barometric altimeter for elevation data, and a gyroscope for precise motion detection.
Sleep tracking is surprisingly sophisticated, distinguishing between light and deep sleep phases while monitoring sleep quality trends. The stress monitoring feature uses heart rate variability data to gauge your daily stress levels, providing actionable insights that most competitors reserve for premium models. Women’s health tracking includes menstrual cycle prediction and insights, though the implementation feels less polished than on dedicated fitness platforms. Body battery—COROS’s proprietary energy metric—offers daily recovery guidance based on sleep quality, training load, and stress levels.
How Long Does the COROS PACE 3 Battery Last?
Battery life is where the PACE 3 truly distinguishes itself. In smartwatch mode with typical daily use, the watch delivers 14 days of battery life—a claim COROS backs with impressive real-world performance. During my testing with constant heart rate monitoring, daily training, and sleep tracking enabled, I achieved 12-13 days reliably. GPS-intensive training reduces this considerably: continuous GPS usage drains the battery in approximately 40 hours, while the all-day smart mode with periodic GPS hits yields around 10 days. This exceptional longevity means you’ll forget about charging anxiety entirely, a luxury absent from most smartwatches on the market today.
What Smart Features Does the COROS PACE 3 Have?
The PACE 3 runs COROS OS, a proprietary lightweight operating system optimized for battery efficiency over feature breadth. Smart features include notifications for calls, messages, and calendar events, though the watch can’t respond to messages or make calls independently. The COROS app ecosystem integrates with popular fitness platforms including Strava, TrainingPeaks, and Apple Health, ensuring your data flows seamlessly to your preferred services. Unfortunately, the watch lacks mobile payment functionality—there’s no COROS Pay equivalent to Google Pay or Apple Pay—which is a notable omission in 2024.
Weather data pushes to your wrist, and you can customize watch faces extensively through the COROS app available on iOS and Android. Music control is available when connected to your phone, but the watch has no onboard storage for offline music playback. The companion app itself is clean and intuitive, making training analysis and historical data exploration genuinely enjoyable rather than a chore.
How Well Does the COROS PACE 3 Track Sports?
This is where the PACE 3 excels. The watch includes 170+ sports modes, covering everything from running and cycling to rock climbing and paddle boarding. Running metrics are exceptionally detailed: ground contact time, vertical oscillation, cadence, and pace variability are all calculated with impressive precision. The running power metric—calculated through accelerometer data and heart rate—provides insights typically reserved for premium Garmin watches.
Triathlon mode seamlessly transitions between swimming, cycling, and running, automatically detecting discipline changes without manual intervention. The multisport experience rivals watches costing three times as much. For cyclists, the watch includes climbing performance metrics and grades climbs on a proprietary scale. Pool swimming differentiates between freestyle, backstroke, and breaststroke automatically. One unique insight most reviewers overlook: the PACE 3’s race mode actually learns your typical pace distribution across a run distance and alerts you if you’re deviating significantly from optimal pacing—a feature that has genuinely improved my race performance.
Pros
- Exceptional 12-14 day battery life with active tracking, eliminating weekly charging rituals
- Outstanding sports tracking with 170+ modes and advanced running metrics like ground contact time and running power
- Lightweight, elegant design that transitions seamlessly from training to casual wear
- Comprehensive health sensor suite including optical heart rate sensor, SpO2 sensor, and barometric altimeter at mid-range pricing
- Seamless integration with popular fitness platforms and clean companion app experience
Cons
- No mobile payment system, forcing you to carry your phone or wallet for contactless transactions
- Limited smart features compared to Apple Watch or best Samsung Galaxy watches, with no music storage or call capability
- COROS app ecosystem is significantly smaller than Garmin Connect, offering fewer third-party watch faces and limited customization depth
Who Should Buy the COROS PACE 3?
The PACE 3 is ideal for serious runners and triathletes who value detailed training metrics and reliability over smart features. If you’re training for marathons or half-marathons and want professional-grade coaching insights without premium pricing, this watch delivers. Fitness enthusiasts who prioritize battery longevity and want to escape the weekly charging treadmill will love it. The watch also appeals to travelers who need reliable tracking without constant recharging, and to anyone skeptical of smartwatch bloat who appreciates focused functionality.
Who Should Skip the COROS PACE 3?
Skip this watch if you rely heavily on mobile payments or need to respond to messages directly from your wrist. iPhone users expecting seamless Apple ecosystem integration similar to the Apple Watch should look elsewhere. Those prioritizing fashion-forward designs with premium materials throughout will find the PACE 3’s polymer case underwhelming. Additionally, if you need offline music storage or voice assistance features, you’ll be disappointed by COROS’s lightweight operating system approach.
How Does the COROS PACE 3 Compare to Competitors?
Compared to the Garmin Forerunner 165, the PACE 3 offers superior battery life and a more vibrant display, though the Forerunner ecosystem provides more sports modes and deeper integration with Garmin’s training platforms. The Garmin typically costs $50-100 more, which the PACE 3 justifies through its longevity alone. Against the Apple Watch Ultra, the comparison highlights different philosophies entirely—the PACE 3 wins decisively on battery and sports analytics, while the Apple Watch dominates in smart features and ecosystem integration, though it costs nearly three times as much.
