Wrist-based heart rate may suit your needs on race day, but when it comes to training and recovery, you might want more dialed-in data. With the addition of a heart rate strap, you’ll get to tap into additional metrics, including VO2 max estimate, lactate threshold, race predictor and recovery advisor and more.
Advanced Running Dynamics
Advanced running dynamics6 help you measure ground contact time balance, stride length, vertical ratio and more.
Stride length: measures the length of your running stride, which will have a high correlation to pace.
Ground contact balance: measures your balance during ground contact to discover you’re running symmetrically.
Vertical ratio %: the cost of moving forward toward your destination; a low score indicates a small cost or “bounce” for a large stride length.
