Best Sport Watches
The "best" running watch or GPS sports watch is a personal choice and much depends on the amount of detail you want from your runs.
Beyond just simple tracking and pace information, the latest watches will feed back everything from heart rate data to detailed observations of your running style. In short, GPS watches are becoming essential tools in the runner's arsenal.
Polar’s top of the line fitness watch is more than double the price of the excellent M400, and though it boasts an even wider feature set, including easy profile switching depending on your activity, beefed up smart coaching features, support for swimmers and a nifty Recovery mode that’ll tell you how long to wait before getting back on the track again, it's debateable that the extra is worth it.
