Why buy each?

Garmin Forerunner 970

ECG, flashlight, and sapphire lens

The FR970 is the first Forerunner with ECG and a built-in LED flashlight — plus a sapphire crystal lens and titanium DLC case for durability that rivals the Fenix 8.

Full color TopoActive maps + Triathlon Coach

Turn-by-turn navigation on preloaded worldwide TopoActive maps, combined with AI-powered Garmin Triathlon Coach structured training plans — a premium combination at any price.

Running dynamics + Elevate Gen 5

Full biomechanics suite (cadence, vertical oscillation, ground contact time, running power) plus Garmin's most advanced heart rate sensor with skin temperature monitoring.

Garmin vivosmart 5

Garmin Body Battery in a band

Body Battery energy monitoring — the feature Garmin is known for — in a wristband that's thinner than most fitness trackers.

HRV status and stress tracking

Continuous heart rate variability monitoring and all-day stress tracking give a more complete picture of recovery and readiness than step counts alone.

Works with Garmin Connect ecosystem

All data syncs to Garmin Connect, compatible with thousands of third-party apps, coaches, and integrations across the Garmin platform.
