Why buy each?

Garmin Forerunner 170

Training Readiness at entry level

Training Readiness, full Training Status, and wrist-based running power — analytics previously reserved for Garmin's mid-range — now on a $299.99 watch.

AMOLED display and 10-day battery

A bright 1.2" AMOLED touchscreen with a traditional 5-button design, up to 10 days of battery in smartwatch mode and around 17 hours of GPS.

Garmin Pay and 80+ sports apps

Contactless payments arrive on the entry Forerunner for the first time, alongside 80+ built-in sports apps and Garmin Coach adaptive training plans.

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.
