What to Look for When Buying a Fitness Tracker vs Smartwatch for Running

Choosing between a fitness tracker and a smartwatch for running comes down to a few critical factors. Here’s what to consider before spending your money:

• GPS Accuracy: If you run outdoors, built-in GPS is non-negotiable. Fitness trackers sometimes use connected GPS (via your phone), while premium smartwatches and running watches usually have standalone multi-band GPS. The difference in accuracy matters most on trail runs or in urban canyons.
• Battery Life: Smartwatches like the Apple Watch Series 10 may need charging every night, while fitness trackers like the Amazfit Band 7 can last up to 18 days. If you’re training for long-distance events, battery life should be a top priority.
• Running Metrics: Look for cadence tracking, pace alerts, heart rate zones, VO2 Max estimation, and training load analysis. Dedicated running watches like the Garmin Forerunner 265 go much deeper than most smartwatches on these metrics.
• Comfort and Weight: A device you wear all day and night should feel comfortable. Fitness trackers are generally lighter and slimmer, making them less intrusive during long runs and sleep.
• Ecosystem Compatibility: Apple Watch only works with iPhone. Samsung Galaxy Watch is best with Android. Garmin and Fitbit work across both platforms. Choose one that fits your phone and preferred apps.
• Budget: Fitness trackers typically cost less than smartwatches. However, dedicated GPS running watches like the Garmin Forerunner 265 can cost as much or more than a mainstream smartwatch. Set your budget and prioritize the features that matter most for your training.
