"Garmin® Forerunner® 170 GPS Running Smartwatch: The Garmin® Forerunner® 170 is the running smartwatch for runners who've moved past the beginner stage and want sharper feedback on how training is actually going. It's a lightweight, purpose-built GPS running watch with a bright 1.2-inch AMOLED touchscreen, wrist-based heart rate, and the kind of training and recovery metrics that used to live on watches twice the price, training readiness, training status, HRV status, and acute load, so you can balance hard days and easy days with real data instead of guesswork.Garmin Coach™ adaptive training plans handle the heavy lifting on race prep, from 5K through half marathon, and daily suggested workouts adjust to how you slept and recovered. You also get wrist-based running dynamics (cadence, stride length, ground contact time, running power), 80+ built-in sports apps for cross-training, and Garmin Pay™ for contactless payments mid-run. Battery runs up to 10 days in smartwatch mode and 20 hours with GPS, plenty for a long-run weekend without a charge.Why Our Fit Experts Love This Watch""The 170 is where most runners I work with will land once they're training for a real race. Training readiness and HRV status give you a clearer read on when to push and when to back off, and it's still small and light enough to disappear on your wrist on a long run.""- Nathan, Road Runner Sports Fit Expert, San DiegoWho It's Best ForBest for intermediate runners building toward a 5K, 10K, half marathon, or first marathon who want a true running smartwatch with deeper recovery and performance feedback.
