Described by Garmin as ‘the expert’, this is for the experienced runner who wants a deeper look into their running style and to work on improving their form. When connected with a heart rate monitor it can present running dynamics data such as ground contact time, cadence, and vertical oscillation- from there it can really help the experienced runner pinpoint exactly where they need to make adjustments to their running. In addition to this data, this state of the art tracker can calculate race time predictions and estimate how long you need for recovery depending on your efforts on your last run- it quite literally sets targets for you, and pushes you to better previous times and distances!
