Garmin Forerunner 235 GPS Running Watch: Make the most of your workout with this watch, which uses a wrist-based Elevate heart rate monitor to calculate your VO2 max and help you predict race times for various distances. Track your activity levels and receive a nudge when you have been sitting for too long, and monitor your steps taken, calories burned, distance traveled and sleep quality and quantity for an overall picture of your physical fitness.
Love the Forerunner 235. GPS connects quickly, and is accurate. Battery seems pretty long lasting when not in GPS mode. Love that the HRM is part of the watch, and not a chest strap. Easy to use. Only problem is that it is very big on small wrists, and the optic sensor is uncomfortable against my wrist bones. But if I wear the face against my inner wrist, it is fine. Love the fount of information that is at my fingertips.
