HRV Status Feature

Garmin's HRV Status analyzes your overnight HRV trends over 7+ days, providing a color-coded status (Low, Balanced, High) with context about whether changes are expected based on training load. This removes the guesswork from interpreting raw HRV numbers.

Training Readiness

Combines HRV, sleep, recovery time, and acute training load into a single Training Readiness score each morning. The score helps you decide whether to push hard or take it easy—similar to Whoop but without subscriptions.

Battery That Lasts

With up to 29 days in smartwatch mode (or 89 hours in GPS mode), you'll rarely miss sleep data due to a dead battery. This multi-week battery makes the Fenix ideal for expeditions and multi-day events.
