Garmin Coach
These adaptive training plans feature guidance from expert coaches and free training plans that adapt to you and your goals. Workouts sync right to your watch.
Built-In Sports Apps
Switch up your workout routine with activity profiles for cycling, pool swimming, indoor rowing, elliptical, stair-stepper and more.
Wrist-Based Heart Rate
The watch constantly samples your heart rate4 and will alert you if it stays too high or too low while you're at rest. It also helps gauge how hard you work during activities. Even underwater.
Multi-GNSS
Access multiple global navigation satellite systems (GPS, GLONASS and Galileo) to track in more challenging environments than GPS alone.
Running Dynamics
When used with a compatible accessory, Forerunner 945 measures crucial running metrics such as cadence, stride length, ground contact time and balance and more.
Vo2 Max
Train smarter with VO2 max, an indicator of how you can expect to perform. This metric even accounts for changes in performance that could be caused by heat or altitude.
Performance Condition
While you run, analyse pace, heart rate and heart rate variability for a real-time assessment of your current ability to perform.
Training Status
This metric evaluates your recent exercise history and performance indicators to let you know if you're training productively, peaking or overreaching.
Training Effect
See how your workouts influence the development of endurance, speed and power with aerobic and anaerobic training effect feedback.
Training Load
This stat measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
Extended Battery Life
Get up to 2 weeks of battery life in smartwatch mode and 10 hours in GPS mode with music. Use UltraTrac™ mode to make sure you've got enough juice to outlast your longest race.
