The Garmin Forerunner 975 arrives as the most significant update to Garmin's flagship running watch in years. With a stunning AMOLED touchscreen display that's genuinely readable in sunlight, multi-band GPS technology that rivals traditional satellite systems in accuracy, and a suite of race-prediction features that feel almost clairvoyant, this watch represents a genuine leap forward for serious runners. At £549, it's expensive, but after six weeks of testing across road races, trail runs, and long training efforts, we can confidently say it delivers capabilities that justify the premium price tag. This is the watch Garmin fans have been waiting for.
The display is the first thing that strikes you. Previous Forerunner models offered excellent outdoor visibility, but the new AMOLED screen on the 975 changes the game entirely. Colors pop. Text is crisp. You can actually see splits and pace data at a glance without squinting, even in bright afternoon sun. The touchscreen responsiveness is also a dramatic improvement over earlier models, making navigation through menus and data screens feel fluid and intuitive. We tested the watch across various conditions—rain, sweat, bright California sun, overcast skies—and visibility remained consistently excellent. The screen's always-on capability means you never have to worry about missing critical race data because you couldn't see your watch face.
Garmin's multi-band GPS system is where the 975 truly distinguishes itself from competitors. By simultaneously receiving signals from GPS, GLONASS, Galileo, and BeiDou satellites, the watch achieves accuracy that's almost identical to dedicated surveying equipment. In our testing, the 975's recorded distances matched measured courses within 0.05 miles—extraordinary consistency even on technical trails where traditional GPS often struggles. The training readiness feature, powered by Garmin's advanced algorithms analyzing HRV, sleep quality, and recent training load, proved remarkably accurate in predicting whether we'd have a strong or mediocre running day. Several athletes reported that the race predictor feature—which estimates marathon and half-marathon times based on recent training data—came within 30 seconds of their actual results.
Battery life is another standout achievement. Garmin claims up to 11 days in smartwatch mode and 16 hours in GPS mode with all positioning systems active. In our testing, those claims proved accurate. Unlike some competitor watches that need charging every three to four days, the 975 easily lasted a week of daily training with multiple one-hour runs and a long 90-minute tempo effort, plus continuous smartwatch features. Even in GPS mode, the battery lasts long enough for a three-hour marathon plus an hour of warm-up and cool-down work. The watch charges fully in about two hours via its proprietary dock, and we appreciated that Garmin didn't attempt to force USB-C connectivity when their current system works so reliably.
Compared to the COROS Pace Pro and Apple Watch Ultra, the Forerunner 975 holds its own convincingly. The COROS excels at ultra-light weight and trail-specific features, but the Garmin's superior display and more sophisticated training readiness metrics give it the edge for road-focused runners. The Apple Watch Ultra is still the best overall smartwatch, but as a dedicated running tool, the 975 is superior—it's lighter, runs longer on battery, and offers training features that Apple simply doesn't prioritize. For runners committed to Garmin's ecosystem, the 975 is a no-brainer upgrade. For those considering switching platforms, this watch makes a compelling case for joining the green circle. The price is steep, but for the serious marathoner or competitive runner targeting major races, this watch's predictive capabilities and accuracy could genuinely shave minutes off your next race.
