How accurate is the Google Fitbit Edge's heart rate during running?
The Google Fitbit Edge delivers heart rate readings that closely match high-end devices during workouts, offering an average heart rate measurement within a few beats per minute of the Garmin Fenix 9 Pro. This suggests the Edge’s LED-based PPG sensors and algorithms provide dependable heart rate tracking for fitness enthusiasts, which is crucial for monitoring exercise intensity, calorie burn, and recovery. Expect good accuracy after an initial period of adaptation to your movement patterns.
Why does the Google Fitbit Edge overestimate GPS distance compared to Garmin Fenix 9 Pro?
When tested on a 5km run, the Fitbit Edge showed a consistent overestimation of running pace and total distance by around 6%, measuring 5.45 km versus Garmin’s 5.15 km. This discrepancy likely stems from differences in GPS technology and satellite signal processing: Garmin’s multi-band SatIQ GPS is optimized for precise tracking even in challenging environments, whereas Fitbit’s GPS, though functional, is less sophisticated. While a 6% variance is minor for casual users or longer races, it may be significant for runners who require more precise distance tracking.
What are the practical implications for choosing between Fitbit Edge and Garmin Fenix 9 Pro?
If your priority is reliable heart rate monitoring at an affordable price, the Google Fitbit Edge provides strong performance near that of premium models. However, for highly accurate GPS distance and pace tracking—critical for competitive running or detailed training metrics—the Garmin Fenix 9 Pro remains superior despite its higher cost. Casual runners should weigh the importance of GPS precision against budget, while serious athletes may prefer Garmin's proven accuracy. Testing over varied routes and conditions is recommended to confirm device performance for your needs.
