Apple Watch vs Garmin for Running: A Hands-On Comparison — Which Watch Suits Taiwan Runners Best?

Introduction

In Taiwan’s running watch market, Apple Watch and Garmin are the two dominant choices, together accounting for more than 70% of the market. Apple Watch draws large numbers of users through its ecosystem integration and stylish design, while Garmin wins over serious runners with its depth of sports science and battery life. So which one is actually better for running? This article compares the two head-to-head across real-world features to help you make the right choice.

Hardware Specifications Compared

GPS Accuracy: Mountain Trails vs. Urban Streets

Apple Watch Ultra 2 uses L1/L2 dual-frequency GPS. In Taipei’s downtown “urban canyons” of tall buildings, positioning drift is noticeably improved over the previous generation, but in densely canopied areas like Yangmingshan, route deviations of 5–15 meters occasionally still occur.

Garmin Forerunner 965’s multi-band GPS performed consistently across most tests, and Taiwanese trail runners found that on mid-mountain trail sections, its recorded routes matched the actual path more closely.

Real-world verdict: On paved road running, the difference between the two is minimal; for trail and mountain running, Garmin performs more consistently.

Depth of Training Analysis

This is where the gap between the two is largest.

Apple Watch’s training analysis:

• Tracks training volume via Apple Health
• Heart rate zone analysis (5 zones)
• VO2max estimate (Fitness Level)
• Training load (requires a third-party app such as Athlytic)
• Running power (requires a Stryd accessory)

Garmin’s training analysis (native):

• Full running dynamics (vertical oscillation, ground contact time, stride length)
• Training Status — determines overreaching/maintaining/peaking state
• Performance Condition curve
• Daily Suggested Workouts
• Recovery time recommendations
• Marathon finish-time prediction

Clear advantage: For runners serious about structured training, Garmin’s native training-science toolset is far more complete than Apple Watch’s.

Everyday Use and Ecosystem Integration

Apple Watch’s strengths:

• Deep integration with the iPhone ecosystem — notifications, Apple Pay, and Siri all work smoothly
• The Apple Watch App Store offers a rich selection of third-party running apps
• Music control is most intuitive when paired with AirPods
• Sleep-tracking interface is easier to read than Garmin’s

Garmin’s strengths:

• Battery can last 2–3 weeks in typical smartwatch mode
• Battery life is more than sufficient for long-distance events (ultramarathons, triathlons)
• Garmin Coach training plans can be downloaded, with the watch vibrating to deliver workout instructions directly
• Connect IQ apps extend functionality (Taiwanese developers have also built localized apps)

Heart Rate Accuracy

Both watches’ optical heart rate sensors deliver acceptable accuracy (±5 bpm error) during steady-state aerobic pace. However, during high-intensity interval running, where heart rate changes rapidly, both show some lag. It’s recommended to pair either watch with a chest strap heart rate monitor (such as the Polar H10 or Garmin HRM-Pro) for more accurate interval training data.

Practical Recommendations

• Everyday life + light training: Apple Watch is the better fit — excellent ecosystem integration and a more versatile look
• Training for marathon distance or beyond: Garmin’s depth of training analysis and battery life are non-negotiable advantages
• Limited budget: The Garmin Forerunner 265 (~NT$14,000) delivers about 80% of Garmin’s functionality at a better price-to-performance ratio
• Already own an iPhone and don’t want to carry two phones’ worth of devices: The Apple Watch Ultra 2 is an all-around choice, but you’ll need to accept the higher price
• Ultramarathons or triathlons: The Garmin Fenix 7 series or MARQ series is the ultimate choice

Conclusion

Apple Watch and Garmin aren’t a matter of one being absolutely superior — they serve different needs. Apple Watch is the best smartwatch; Garmin is the best running tool among sports watches. Clarify your primary use case first, and you’ll make a choice you won’t regret.
