Customizable data pages and activity profiles make it easy to display your data the way you want to see it. You can easily see your GPS speed and distance, your interval training and advanced workout statistics, your VO2 max., your training status, your aerobic and anaerobic training effects, the activity history on the watch, and much more.
In addition to intuitive analysis of your activities, the Garmin Forerunner 645 features a number of heart rate features including HR zones, HR alerts, HR calories, % HR max., % HRR, recovery time, auto max HR, and HR broadcast.

- Tune up Your Training
- Let the Forerunner 645 Sport Watch measure crucial running metrics that you can use to analyze your performance. Biomechanical measurements, such as cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio, are the key to understanding your form so you can bring your best on race day. These metrics are available with the addition of a compatible heart rate strap or the compact Running Dynamics Pod, which clips right onto your waistband.

Training status is a performance monitoring tool that automatically evaluates your recent exercise history and performance indicators to let you know if you're training productively, peaking, or overreaching. The anaerobic training effect metric opens a window of insight to a critical dimension of training, telling you how your training is improving your ability to push the limits. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
