Get a training partner that won't talk and will tell you everything you need to know about your training runs—the Polar RS200sd Heart Rate Monitor. Not only can you track your heart rate zones throughout your run, you can combine this with speed and distance data as the included S1 foot pod tracks these important functions. Use the Event Countdown Timer to track your progress up to your next race. After a hard run, jump in the water for a quick swim and leave the RS200sd on as it's water resistant up to 50 meters.
Bottom Line: The Polar RS200sd Heart Rate Monitor will be the smartest training partner you've ever had.
