A smart, intuitive training computer for runners and cross-training athletes, the Polar RS300X SD wrist heart rate monitor helps you to train at the right intensity with personal training zones. The RS300X SD comes with Polar's S1 foot pod, which accurately measures your running speed/pace and distance. Committed runners will find the most value in the real-time pace and distance measurement of the S1 foot pod. And even though it attaches to your shoe laces, it's so light that you'll forget it's even there, which means it won't affect your running performance.
