The Garmin Forerunner 170 transforms running from guesswork into guided progress. Designed specifically for runners who want to move beyond basic tracking, this GPS smartwatch combines personalised training plans with advanced running metrics that were once exclusive to professional athletes.
Built around Garmin's proven GPS technology and comprehensive health monitoring, the Forerunner 170 adapts to your current fitness level and guides you towards measurable improvement. Whether you're training for your first 5K or chasing a marathon PB, this watch provides the data and direction you need to run smarter, not just harder.

The perfect balance of guidance and performance tracking
Personalised Training Plans
Adaptive coaching adjusts to your progress with structured workouts designed to safely build endurance and speed without overtraining.
Advanced Running Metrics
Track cadence, stride length, ground contact time, and vertical oscillation to analyse and improve your running form.
Multi-GNSS Positioning
GPS, GLONASS, and Galileo satellite systems deliver precise tracking accuracy in challenging environments like dense forests or urban canyons.
20-Hour GPS Battery
Extended GPS runtime handles ultra-marathons and multi-day adventures, whilst smartwatch mode lasts up to 10 days between charges.
AMOLED Always-On Display
Bright, high-resolution colour screen remains visible in direct sunlight with customisable data fields and watch faces.
Comprehensive Health Monitoring
24/7 heart rate, Pulse Ox, sleep analysis, and stress tracking provide complete wellness insights beyond just running.
Smart Coaching That Adapts to You
The Forerunner 170's training intelligence goes beyond basic pace tracking. Built-in coaching plans automatically adjust based on your performance, recovery metrics, and progress towards your goal. Whether you're targeting a sub-30 minute 5K or preparing for your first half-marathon, the watch provides daily workout guidance with clear instructions and real-time feedback.
Recovery metrics help prevent overtraining by monitoring heart rate variability, sleep quality, and training load. The watch learns your patterns and suggests rest days when needed, ensuring your training builds fitness rather than fatigue.
Professional-Grade Running Analytics
Advanced running dynamics reveal exactly how you move, with metrics like ground contact time balance and vertical oscillation helping identify inefficiencies in your stride. Race predictor estimates your finishing times for 5K, 10K, half-marathon, and marathon distances based on your current fitness level.
The built-in barometric altimeter tracks elevation changes accurately, making it ideal for trail runners and those training in hilly terrain. Training Effect scores quantify how each workout improves your aerobic and anaerobic fitness, taking the guesswork out of training progression.

Legal guarantee
Minimum two-year legal guarantee protection for goods sold in the European Union.
Consumers can claim their rights under the legal guarantee of conformity, for example if goods:

- free repair or free replacement;
- in some cases, a price reduction or full reimbursement.
Some countries have a longer legal guarantee period. For second-hand goods, a shorter period may apply, but not less than one year.
