The direct answer: Coros Pace Pro is the best value by a wide margin at $299, Garmin Forerunner 970 is the most feature-complete at $749 (nearly 2.5x the price), and Polar Vantage V3 sits in between at $599.95 with the strongest smartwatch-mode battery life of the three. Unless you specifically need Garmin’s newest hardware extras — a built-in speaker, flashlight, and the latest running-economy metrics — Pace Pro covers the fundamentals most runners actually use for under half the price.
At a Glance
- Best value: Coros Pace Pro ($299) — 38-hour GPS battery and an AMOLED display for less than half of Garmin’s price.
- Best all-around feature set: Garmin Forerunner 970 ($749) — speaker/mic, flashlight, and the newest running metrics, at the steepest price.
- Best smartwatch-mode battery life: Polar Vantage V3 ($599.95) — up to 140 hours in Eco training mode and 10 days as a daily watch.
Garmin Forerunner 970: The Feature-Complete Flagship
Forerunner 970 is priced at $749 — a real jump from the previous FR965’s $599 launch price — and it earns that increase with genuinely new hardware. It’s the first Forerunner with a built-in speaker and microphone for calls, plus an LED flashlight with both white and red light modes, a sapphire crystal display cover, and Garmin’s Elevate Gen 5 heart rate sensor with ECG capability. New running metrics include Impact Load Factor, Running Economy, and Step Speed Loss, alongside a projected race-time predictor.
GPS battery life varies by accuracy mode: up to 26 hours in GPS-only mode, 23 hours using Garmin’s SatIQ auto-select mode, or 21 hours with full multi-band all-systems GNSS — dropping to 12-14 hours with music playback running. Smartwatch mode extends to roughly 15 days. Reviewers have generally called the 970 an “evolutionary,” not revolutionary, upgrade — real improvements, but not a reason to jump ship from a recent Forerunner if you already own one.
Coros Pace Pro: The Value Pick That Undercuts Everyone
Coros Pace Pro launched with a price adjustment in November 2025 that settled it at $299 in the US — less than half of Garmin’s flagship. It runs a 1.3-inch AMOLED display and rates up to 38 hours of GPS battery life, a genuinely strong figure for a watch at this price tier.
What you give up at this price tier is the extras: no built-in speaker/mic, no flashlight, and a smaller third-party ecosystem than Garmin’s Connect IQ. For runners who care primarily about accurate GPS tracks, solid training load metrics, and long battery life without paying for calling or flashlight hardware they won’t use, Pace Pro is hard to beat purely on value.
Polar Vantage V3: The Battery-Life Specialist
Polar Vantage V3 runs $599.95 and differentiates itself most clearly in battery-life engineering: up to 43 hours in Performance Training mode with dual-frequency GPS and full heart-rate tracking, stretching to as much as 140 hours in Eco Training mode with single-frequency GPS and reduced recording frequency, and up to 10 days in everyday Smartwatch mode with continuous heart rate and notifications.
That Eco mode figure matters specifically for ultra-distance athletes — a 100-mile race or multi-day event is exactly the scenario where Vantage V3’s battery flexibility becomes a genuine differentiator rather than a marketing number, since neither rival publishes a comparable extended-endurance battery mode at this length.

Which One Should You Actually Buy?
Get Coros Pace Pro if you want strong GPS accuracy and training metrics without paying flagship prices — for most runners training for anything short of true ultra-distance events, it covers the fundamentals competently. Get Garmin Forerunner 970 if you specifically want on-wrist calling, a flashlight, and Garmin’s latest running-economy metrics, and the price premium doesn’t bother you. Get Polar Vantage V3 if ultra-distance battery flexibility is a real requirement — its Eco mode’s 140-hour rating has no direct equivalent in this comparison.
How We Compared

FAQ
Which GPS running watch is cheapest?
Coros Pace Pro at $299, less than half the price of Garmin Forerunner 970’s $749 and meaningfully cheaper than Polar Vantage V3’s $599.95.
Which watch has the best battery life for ultra-distance races?
Polar Vantage V3, with an Eco Training mode rated up to 140 hours — well beyond what either Garmin Forerunner 970 or Coros Pace Pro publishes for extended-endurance GPS tracking.
Does the Coros Pace Pro have a speaker for calls like the Garmin?
No. Only Garmin Forerunner 970 includes a built-in speaker and microphone for on-wrist calls among these three watches.
Is Garmin Forerunner 970 worth the price premium over Coros Pace Pro?
Only if you’ll actually use its extras — on-wrist calling, the flashlight, and Garmin’s newest running metrics. For core GPS accuracy and training-load tracking, Pace Pro covers similar ground for less than half the price.
