Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.
Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.
Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.
Body Battery energy monitoring — the feature Garmin is known for — in a wristband that's thinner than most fitness trackers.
Continuous heart rate variability monitoring and all-day stress tracking give a more complete picture of recovery and readiness than step counts alone.
All data syncs to Garmin Connect, compatible with thousands of third-party apps, coaches, and integrations across the Garmin platform.
