Polar sport zones that help you train at the right intensity. 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).

Interval trainer (HR, pace, distance) guided workouts -- Create your personal multizone workouts with heart rate/speed/distance and timing guidance. Polar Interval trainer allows you to create and name your own favorite workouts based on time, heart rate, speed/pace or distance guidance with up to three linked timers or distances and up to three target zones.

Event Countdown Timer that lets you set your goal and stay motivated. The event countdown timer keeps your motivation high by showing how many days are left before your next running event (e.g. Boston 23 days).

Included: Polar S1 wireless foot pod for speed and distance sends data to the wrist monitor. The Polar S1  foot pod is highly accurate. It is not a pedometer, it does not count steps, nor does it rely on an equal stride length. The Polar foot pod measures 360 degree, 3-D, forces of inertia (speed, magnitude, impact, direction etc). These sensitive accelerometers then translate these measurements in to real time speed and distance with approximately 95-97% accuracy.
