Vertical Ratio – the cost-benefit ratio with stride length.Reducing the amount of bounce in your stride can improve your running efficiency/economy. Vertical Oscillation – The amount of ‘bounce’ in your running motion.Ground Contact Balance – Symmetry between left and right foot when running.Ground Contact Time – The time your foot spends on the ground with each stride.This quite literally opens up the following running metrics on the FR245. The main reason the Forerunner 245 is better than the Vivoactive 4 (for runners specifically), is because it boasts support for Garmin advanced running dynamics. It also opens up quite a few more sports modes. This means it’s slightly better for measuring vertical movements during endurance exercises like running and cycling. Barometric Altimeter (Vivoactive 4) – Only the Vivoactive 4 has a built-in barometric altimeter.This can be a great tool for achieving target race times. Virtual Partner (Forerunner 245) – Garmin’s virtual partner technology allows you to set a pace for the Virtual Partner and race against it.Race Predictor (FR245) – The Forerunner 245 will use your VO2 max estimate and your training history to predict a potential race time.These are some pretty neat bonus features to. It basically tells you when you’re over training, when your under-training, and when you’re getting it exactly right. To make a long story short, the 245 Music does everything the 245 does while also offering Wi-FI connectivity and music storage.

Golf Mode (Vivoactive 4) – This is a big selling point for people who play golf regularly.This means real time access to cadence, stride length and other running specific metrics. Advanced Running Dynamics (FR245) – Only the Forerunner 245 supports advanced running dynamics.A lot of runners prefer a ‘button only’ setup.
