When I first started running seriously in April 2025, I felt a strong urge to quantify my progress. I remember spending $200 on my first fitness tracker, driven by the hope that this would help me improve my performance. It was frustrating to find the right device in a market flooded with options. After nearly a year of testing, I can share my insights comparing two heavyweight contenders: the Garmin Forerunner 255 vs. the Apple Watch Series 9. In this guide, I’ll help you determine which is the best fitness tracker for runners in 2026.
Understanding the Basics of Fitness Trackers
Before we dive into the specifics of these two fitness trackers, let’s clarify what makes a good running watch.
Essential Features to Consider
- Accuracy: GPS accuracy is crucial for tracking your distance and pace.
- Heart Rate Monitoring: Continuous heart rate tracking helps gauge your workout intensity.
- Battery Life: Longer battery life is vital, especially for long runs or races.
- Water Resistance: If you run in the rain or tackle long-distance swims, water resistance matters.
- App Integration: Compatibility with other fitness apps can enhance your tracking experience.
What Makes a Tracker Great for Runners?
- Built-in Running Profiles: Specific modes for different types of runs (e.g., trail, interval).
- Post-run Insights: Recovery time predictions and VO2 max calculations for performance improvement.
- Customizable Alerts: Alerts for pace, heart rate, or distance to keep you on track.
These features could influence your decision significantly. In my experience, I found some of these attributes more helpful than I anticipated, like the customized alerts I set on my Garmin and the thorough analytics offered through Apple’s fitness app.

What Most Guides Get Wrong
Not All Trackers Are Created Equal

- Battery Life Ignored: High-end smartwatches often sacrifice battery life for features. Many runners prefer extended battery life over added apps.
- Underplaying Comfort: Comfort is key for a fitness tracker, especially during long runs. Look for ergonomics and adjustability, which many reviews overlook.
Is It Worth It?
Evaluating whether to invest in a fitness tracker like the Garmin Forerunner 255 or the Apple Watch Series 9 largely depends on your goals and how you plan to use it.
- Garmin Forerunner 255: If you’re a dedicated runner looking for accuracy and detailed metrics, then this is worth your investment.
- Apple Watch Series 9: If you want an all-in-one device that doubles as a fitness tracker and a smartwatch, I’d say it’s a great buy.
In my experience, spending around $400 for the features of the Forerunner has improved my running significantly. The advanced insights and long battery life are worth every penny for a serious runner.
