Garmin · Running
The Garmin Forerunner® 170 in Whitestone with Whitestone/Cloud Blue Band is a purpose-built GPS running smartwatch designed for runners who want straightforward tools plus meaningful training insight. It combines built-in GNSS for tracking where runs happen with key stats such as pace and distance, along with wrist-based heart rate to help gauge effort.
With Garmin Coach personalized training plans, daily suggested workouts that adapt after every run, and advanced training metrics and recovery insights, it suits anyone building consistency or chasing a new milestone. A 1.2" colorful AMOLED touchscreen display keeps data easy to read, while everyday conveniences like smart notifications and Garmin Pay™ help it fit into daily life when paired features are used as intended.
Display
A 1.2" colorful AMOLED touchscreen display makes it simple to check workout stats and daily information at a glance. The watch also supports an optional always-on mode, plus color filters and watch face customization to tailor how data is shown for different viewing preferences and needs.
Battery
Forerunner® 170 is built for routine wear and consistent training with up to 10 days of battery life in smartwatch mode. For longer sessions, it delivers up to 20 hours in GPS-Only GNSS mode and up to 14 hours in All-Systems GNSS mode, with a Battery Saver Smartwatch mode rated up to 19 days.
Connectivity
When paired with a compatible iPhone® or Android™ smartphone, the watch can deliver smart notifications for emails, texts and alerts. Garmin Pay™ contactless payments add the option to pay from the wrist with participating providers, helping reduce how often a phone or wallet needs to come along.
Training
Forerunner® 170 focuses on the essentials that help runners improve: GPS-based tracking for pace and distance plus wrist-based heart rate to understand effort. Built-in GNSS supports multiple satellite systems, and the watch adds running-focused detail like wrist-based running dynamics and wrist-based running power. It also supports track running with lap distances and distances shown in meters, giving runners clearer feedback whether training outdoors or on the track.
Health
Training can stay on track with daily suggested workouts that adapt after every run, including run-walk workouts. Garmin Coach adaptive training plans can be used to train for an event, reach a milestone, or build fitness with plans that adjust daily based on recovery and health metrics. Advanced training tools such as training readiness, training status, training effect, and recovery time help interpret how current training is going and when it may be time to push or recover.
Connectivity
Wellness features support an everyday view of recovery and readiness. The watch provides morning and evening reports, plus sleep tools like sleep score, sleep coach, sleep stage tracking, and nap detection. HRV status is tracked during sleep to help build a clearer picture of overall health, training, and recovery. Additional tracking includes Body Battery™ energy monitoring, stress tracking, breathing variations insights during sleep, and women’s health tracking in Garmin Connect™.
Navigation
For planning and navigation, courses can be created or found in the Garmin Connect™ app and from third-party platforms, then synced to the watch. On the wrist, mapping and navigation tools include point-to-point navigation, bread crumb trail in real time, Back to start, TracBack®, and Up Ahead. Safety and tracking features include incident detection during select activities and Assistance, which can send a message with live location when triggered; LiveTrack™ location sharing can let friends and family follow real-time location.
