The Complete Guide to Buying a GPS Running Watch: Garmin vs COROS vs Apple Watch In-Depth Comparison

Introduction

GPS running watches have evolved from gear reserved exclusively for elite runners to equipment used by runners of all levels. A good running watch is more than just a timing tool—it records training data, analyzes athletic performance, and plans training schedules. Currently, the three most popular options in the Taiwanese market are Garmin, COROS, and Apple Watch, each with a distinctly different design philosophy and catering to very different user groups.

Garmin: The Standard Answer for Runners

Brand Positioning and Strengths

Garmin is the number one brand choice for runners worldwide, holding over 60% market share at Taiwanese marathons. Its core strengths lie in:

• The most complete running data: VO2max prediction, training status, running dynamics (ground contact time, vertical oscillation, stride length)—unmatched data depth
• Professional training plan scheduling: Built-in structured training programs that automatically generate schedules based on race goals
• Complete ecosystem: Garmin Connect platform has the most users in Taiwan, with robust community features
• GPS accuracy: Multi-system GPS (GPS + GLONASS + Galileo) for precise positioning
• Battery life: Forerunner series lasts 14–26 days, so no frequent charging needed for ultramarathon training

Mainstream Models in Taiwan

Disadvantages

• Relatively traditional interface with a steeper learning curve
• Entry-level models have lower screen resolution
• Some features require a paid subscription (e.g., advanced Garmin Coach training plans)

COROS: The New King of Value for Money

Brand Positioning and Strengths

Chinese brand COROS has risen rapidly in recent years, earning a strong reputation especially in the ultramarathon and trail running communities:

• Excellent battery life: COROS VERTIX 2S delivers up to 140 hours in full GPS mode—an ultramarathon powerhouse
• Outstanding value: 20–40% cheaper than Garmin for equivalent specs and features
• Lightweight design: APEX 2 Pro weighs only 58g, making it one of the lightest watches with comparable features
• Mapping features: Mid-to-high-end models include built-in topographic maps, practical for trail running navigation
• Active updates: Frequent firmware updates with fast addition of new features

Mainstream Models in Taiwan

Disadvantages

• Platform user base far smaller than Garmin’s, with weaker community features
• Some advanced running dynamics metrics (such as ground contact time balance) are less complete than Garmin’s
• Relatively limited official after-sales service channels in Taiwan

Apple Watch: A Running Watch Among Smartwatches

Brand Positioning and Strengths

The Apple Watch is not a pure running watch, but as a combination of smartwatch plus running features, it offers unique advantages:

• Best daily integration: Seamless integration of notifications, payments, and health monitoring (ECG, blood oxygen)
• Touchscreen experience: Large, clear OLED display with the most intuitive operation
• Apple ecosystem: Extremely friendly to iPhone users, with the richest health app ecosystem
• Accurate optical heart rate: The Apple Watch Ultra series has the highest optical heart rate accuracy among smartwatches

Main Disadvantages

• Short battery life: Series 10 lasts about 18 hours, Ultra 2 about 36 hours with GPS—enough for a full marathon but not an ultramarathon
• Insufficient running data depth: Lacks advanced metrics such as VO2max prediction and training status
• High price: Apple Watch Ultra 2 costs NT$29,900, yet you won’t get professional running features comparable to Garmin

Quick Comparison of the Three Brands

Buying Recommendations

Beginner runners (weekly mileage under 20km): Apple Watch S10 or Garmin Forerunner 165—both offer sufficient features with solid after-sales support in Taiwan.

Marathon runners training seriously: The Garmin Forerunner 265 is currently the most recommended mid-range running watch in Taiwan, with complete training data, sufficient battery life, and reliable after-sales service.

Budget-conscious but demanding high performance: The COROS PACE 3 is the best value option on the market right now—NT$7,490 gets you advanced training data and excellent GPS.

Ultramarathon or trail runners: The COROS VERTIX 2S’s battery life is unmatched, making it a popular choice among Taiwan’s hundred-peak runners.

Conclusion

There is no single right answer when choosing a running watch—the key is which aspect matters most to you. Garmin offers the most complete running training ecosystem, COROS challenges the market with better value for money, and Apple Watch suits runners who prioritize everyday smart features. Taiwan has ample opportunities to try these watches in person, so we recommend visiting a store to try them on and feel the wearing comfort before making your decision. A good running watch is a long-term partner that helps you push past your limits year after year.
