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.
The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.
Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.
Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.
