Why buy each?

COROS Pace

38-day battery in a 30g watch

At 30 grams, the Pace 3 is among the lightest GPS watches available — yet delivers 38 days typical use and 17 hours continuous GPS.

Multi-band GPS at entry price

Dual-frequency L1+L5 GPS typically found on $400+ watches — available on the Pace 3 at $229.

COROS EvoLab analytics

Running power, training load, base fitness, threshold metrics, and race predictor — a serious analytics suite that rivals Garmin at a lower cost.

Polar Grit X

40-day battery for trail and ultra runners

Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.

Hill splitter auto-detection

Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.

Wrist running power at mid-range price

Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.
