Why buy each?

Garmin Forerunner 970

ECG, flashlight, and sapphire lens

The FR970 is the first Forerunner with ECG and a built-in LED flashlight — plus a sapphire crystal lens and titanium DLC case for durability that rivals the Fenix 8.

Full color TopoActive maps + Triathlon Coach

Turn-by-turn navigation on preloaded worldwide TopoActive maps, combined with AI-powered Garmin Triathlon Coach structured training plans — a premium combination at any price.

Running dynamics + Elevate Gen 5

Full biomechanics suite (cadence, vertical oscillation, ground contact time, running power) plus Garmin's most advanced heart rate sensor with skin temperature monitoring.

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.
