Garmin release next generation of GPS run watches

The 230 is the simplest watch of these updated models, whereas the 235 and 630 both have heart rate monitors built in amongst other new innovations. 

The 630, proclaimed as Garmin’s most advanced running watch to date, has a mind-boggling list of features, with the ability to track stride length, make V02 max estimates and calculate lactate threshold to name just three.
It’s Wi-Fi enabled so your runs will be automatically downloaded to Garmin Connect, and has a whopping sixteen hours battery life in training mode and four weeks when just being used as a normal watch. What’s more, the built-in everyday activity and sleep trackers will still work in watch mode without eating into the battery life.
