The RS200 was made for goal oriented runners who want to prepare for their first running event or who want to enhance their running experience. Use the Polar Sports Zones and the Event Countdown Timer to manage your training for that key running event. You can even upload your settings to your running computer and then download your workout files to the Polar Running Coach Web Service for analysis. WearLink fabric transmitter included. Get the most out of your RS200 when you add on the optional S1 foot pod (or see RS200SD) to take advantage of the Speed and Distance function.
