With a simple tap of the screen, the Garmin Fore颅runner 610 watch鈥攊ts first touchscreen GPS model鈥攕witches between a mileage counter and a virtual racing partner (you can race friends or yourself). Also cool: the mile-marker alert vibrates instead of just beeping, as its predecessor did, so you won鈥檛 miss a benchmark even when you鈥檙e rocking out.
