In addition, the line-up has also been expanded to include new Garmin Forerunner 230 and 235 running watches as well.

Starting with the Garmin Forerunner 630 (pictured above), users now get notifications on the wrist with a paired smartphone and there's a host of new data collected. The 630 will now record stride length and vertical ratio, which is an expansion of the existing cadence and oscillation metrics, which can be used to make runners more efficient.

It will also guide users on recovery times and readiness by rating lactate threshold and performance condition to inform runners when they're too tired to train and are risking injury. And as with all running watches these days, you can wear it for activity tracking of steps and calories when you're not out for a run.
