Best Smartwatches for Running 2026

The display technology in smartwatches significantly influences readability and battery consumption. AMOLED displays, as seen in the Garmin Forerunner 965 and fēnix 8, provide vibrant colors and high resolutions (454 x 454 pixels), ideal for viewing detailed maps and data in various lighting conditions. However, they tend to consume more power, impacting battery life. Conversely, the Garmin Enduro 3 uses a transflective memory-in-pixel (MIP) display, which excels in sunlight visibility and conserves battery, making it suitable for extended outdoor activities. While MIP displays have less color saturation indoors, they provide an always-on view without significant battery drain.

Battery life is a critical consideration for runners, particularly those engaged in long-distance or multi-day events. The Garmin Enduro 3 stands out with an unparalleled battery life of up to 90 days in smartwatch mode with solar charging, making it ideal for ultra-endurance athletes. In contrast, the Garmin epix Pro (Gen 2) and fēnix 8 offer 16-day battery life, balancing performance with the demands of an AMOLED display. The Forerunner 965 provides a respectable 23-day battery life, leveraging its efficient power management. Charging methods also vary, with proprietary plug chargers being standard across all models, though solar charging in the Enduro 3 offers added convenience for extended adventures.

Accurate GPS is crucial for tracking distance, pace, and route during runs. The Garmin Enduro 3 and fēnix 8 feature multi-band GNSS with SatIQ technology, supporting multiple satellite systems like GPS, GLONASS, and Galileo, ensuring superior accuracy even in challenging environments. The Forerunner 965 and epix Pro also utilize SatIQ, providing reliable location data. These features are essential for trail runners who require precise navigation and real-time updates. While the Garmin Venu 3 offers single-band GNSS, it remains effective for standard running activities, but may lack the enhanced precision found in multi-band models.

Comprehensive health monitoring is a hallmark of modern smartwatches. The Garmin Forerunner 965 and fēnix 8 provide advanced metrics like Training Readiness and HRV Status, essential for optimizing performance and recovery. The fēnix 8 includes a depth sensor for diving up to 40 meters, while the epix Pro offers ECG capabilities with its Elevate Gen 5 sensor, enhancing heart health monitoring. The Venu 3 emphasizes lifestyle features with a built-in speaker and microphone, supporting voice assistants and calls. These health features cater to different user needs, from competitive athletes to those focused on overall well-being.
