    Tune up your training

    We’re making it easier to get the data you need to improve your form. Let Forerunner 645 measure crucial running metrics2 that you can use to analyse 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.
