With the included S1 foot pod, you'll be able to take advantage of the RS400sd's Speed and Distance functions, such as speed, distance and pace per kmph/mph, target pace (with alarms and differential), trip odometer, run distance, totals for mileage, calories and time training, and summaries for distance and speed/pace.

Heart rate monitoring includes maximum heart rate (fitness test-based and age-based), maximum/average of total exercise and of each lap (up to 99 laps), three target zones, and audible alarms. It also offers such timing features as time of day (12/24-hour display), dual time zone, day and date display, stopwatch, and alarm with snooze. It features an oversized display, easy to manipulate buttons while on the run, and a comfortable WearLink fabric transmitter. It also includes the following exclusive Polar features:

• Polar Sport Zones: Polar sport zones provides an easy way to select and monitor the intensity of your training and to follow Polar's sport zones based training programs. The training is divided into five zones based on percentages of your maximum heart rate: very light (50-60%HRmax), light (60-70% HRmax), moderate (70-80%HRmax), hard (80-90% HRmax) and maximum (90-100% HRmax).
• Polar OwnCal: This feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. You can set daily and weekly exercise goals in terms of calorie expenditure with the OwnCal feature. Because the OwnCal tracks both the energy expenditure during one exercise session and the accumulated kilocalories during a longer time e.g. one week, it helps in achieving both short term and long term goals.
• Polar OwnZone: This feature guides you through an appropriate warm-up routine and automatically determines a safe and effective exercise heart rate zone--your OwnZone--while taking into account your current physical condition.

About Polar
The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990s, individuals were looking to heart rate monitors not only for performance training needs, but also for achieving everyday fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as everyday people trying to lose weight. Polar is the leading brand among consumers, coaches, and personal trainers worldwide and the company is committed to not only producing the best products, but also being the leading educator on the benefits of heart rate based exercise.
