Garmin vs COROS: Which GPS Watch is Right for You?
We pit the Garmin Forerunner 965 against the COROS PACE 3 across accuracy, battery life, and features to help you decide.
The Battle
Garmin and COROS represent two very different philosophies in GPS watch design. Garmin goes premium with an AMOLED screen and exhaustive feature set. COROS focuses on battery life, accuracy, and simplicity at a significantly lower price.
For Australian runners, this comparison becomes particularly relevant given our harsh climate conditions and diverse training environments—from the urban streets of Melbourne and Sydney to the remote trails of the Blue Mountains or Grampians. Both brands offer compelling arguments, but understanding their strengths and weaknesses will help you make an informed decision.
Garmin has dominated the GPS watch market for years, building a reputation on comprehensive data collection and analysis. Their watches pack everything from advanced running dynamics to music storage, making them the Swiss Army knife of sports watches. The brand's flagship running models, like the Forerunner 965, represent the pinnacle of training technology.
COROS, the relative newcomer from China, has gained significant traction by focusing on what matters most to endurance athletes: accuracy, battery life, and value. Their approach strips away some of the bells and whistles to deliver exceptional performance where it counts most—during your actual training and racing.
GPS Accuracy
Both watches performed excellently in our testing across various Australian conditions. The Forerunner 965 edged ahead in dense urban environments while the COROS matched it on open trails.
GPS accuracy forms the foundation of any serious training watch, and both manufacturers have invested heavily in improving their satellite reception. The Garmin Forerunner 965 utilises multi-band GPS technology, accessing signals from GPS, GLONASS, and Galileo satellites simultaneously. This proves particularly beneficial in challenging environments like Melbourne's CBD or Sydney's urban canyons, where tall buildings can interfere with satellite signals.
COROS watches also feature multi-band GPS across their range, including the more affordable models. During testing along the Yarra River trail and through the Royal Botanic Gardens, both watches delivered remarkably similar results, with distance variations typically under 0.2% over 10-kilometre runs.
Where differences emerged was in specific challenging conditions. The Garmin's more aggressive processing seemed to handle frequent direction changes better, making it slightly more reliable for track workouts or technical trail running. COROS, meanwhile, showed exceptional consistency on long, steady runs, with some users reporting superior accuracy during ultra-distance events.
Both watches offer customisable GPS settings, allowing you to balance accuracy with battery life. For most Australian runners, either watch will provide more than adequate GPS performance for training and racing needs.
Battery Life
COROS wins decisively here—38 days in smartwatch mode versus 23 for the Garmin.
Battery performance represents perhaps the most significant difference between these two brands, and it's where COROS truly shines. The longevity advantage extends across all usage modes, making COROS particularly appealing for ultra-runners, adventure racers, and anyone who finds themselves regularly away from charging opportunities.
In GPS tracking mode, COROS watches typically deliver 35-60 hours of continuous use depending on the model, while Garmin's AMOLED-equipped watches manage 20-30 hours. For someone training for the Ultra-Trail Australia or planning multi-day hiking adventures in Tasmania, this difference becomes critically important.
The battery advantage stems from COROS's choice to use memory-in-pixel (MIP) displays rather than power-hungry AMOLED screens. While this means sacrificing some visual appeal, the practical benefits for endurance athletes are substantial. You can head out for a week-long camping trip without worrying about charging, or complete back-to-back long training days without battery anxiety.
Garmin's newer AMOLED models do offer superior readability in direct sunlight—a significant consideration for Australian conditions—but the battery trade-off is notable. However, Garmin's solar-equipped models can extend battery life significantly when exposed to strong Australian sunshine, partially closing the gap.
Features and Functionality
Garmin's ecosystem dominance becomes apparent when examining the breadth of features available. The Garmin Connect platform offers comprehensive training insights, detailed recovery metrics, and extensive customisation options. Features like Training Readiness, which combines sleep data, stress levels, and workout history to suggest daily training loads, provide valuable guidance for serious athletes.
Music storage and playback represent another Garmin advantage, allowing you to leave your phone behind during runs while still enjoying your favourite playlists through wireless headphones. This proves particularly valuable for long training runs in areas with poor mobile reception.
COROS takes a more streamlined approach, focusing on core training metrics while maintaining simplicity. Their EvoLab feature provides unique insights like power-to-weight ratios and training load comparisons, often presenting data in ways that feel more intuitive than Garmin's sometimes overwhelming array of metrics.
Both platforms offer structured workout capabilities, but Garmin's integration with platforms like TrainingPeaks and Strava feels more mature. COROS continues to develop their ecosystem, and while improving rapidly, still lags behind Garmin's extensive third-party integrations.
Build Quality and Design
Construction quality varies significantly between the two brands' approaches. Garmin watches generally feel more premium, with higher-quality materials and more refined finishing. The titanium bezels and sapphire crystal displays on higher-end models justify their premium pricing.
COROS focuses on functional design over aesthetic appeal, though their build quality remains solid. The watches feel robust enough for serious training, with many athletes reporting years of trouble-free use in harsh conditions. The button-only interface, while initially requiring adjustment for touchscreen-accustomed users, proves more reliable in wet or cold conditions common in Australian winters.
Both brands offer various case sizes and colours, though Garmin provides more customisation options overall. Strap quality favours Garmin slightly, with more comfortable silicone compounds and better quick-release mechanisms.
How We Tested
Our comprehensive testing methodology involved six months of real-world use across diverse Australian training environments. We evaluated both watches on urban runs through Melbourne's CBD, trail runs in the Dandenong Ranges, track workouts at Olympic Park, and beach runs along the Great Ocean Road.
GPS accuracy testing involved simultaneous wear of both devices during identical activities, comparing distance measurements, pace accuracy, and route mapping precision. We conducted over 50 separate GPS tests ranging from 5-kilometre easy runs to marathon-distance efforts.
Battery life testing included controlled drain tests in various GPS modes, real-world usage patterns simulating typical training weeks, and extreme testing during ultra-distance events. We monitored charging times, battery degradation over the testing period, and performance in various temperature conditions.
Feature testing examined ease of use, accuracy of heart rate monitoring, reliability of smart notifications, and integration with popular training platforms. We also evaluated customer support responsiveness and warranty service quality for both brands.
All testing incorporated feedback from local running groups, including members of Melbourne Marathon Club and Sydney Striders, ensuring our assessments reflected diverse user experiences and preferences.
