If you typically end your workout sessions with more questions than answers, the Polar RS300X G1 Heart Rate Monitor is ready to come to the rescue. Ask it your speed and distance, and the included GPS tech will spit back your stats in real time. The heart-rate-monitor function gives you an accurate snapshot into your overall performance so you can make the call whether to push harder or dial it back. And the ability to view data from previous workouts helps you track your progress over time.
