The Forerunner 945 is a fully featured running and triathlon GPS sports watch. You will find the usual Elevate wrist-based heart rate for 24/7 heart rate monitoring, and GPS and GLONASS coverage. Additionally, the wearable sports a barometer, altimeter, and a compass.

Where the watch stands out most though, is in its detailed analysis of performance. According to Garmin, the Forerunner aggregates past training results and then uses that data to evaluate the amount of effort users exert during fitness sessions, i.e. if you are slacking off or overdoing it. It does this through two new additional metrics, training load and training status.
