RS300X sd

For enthusiast runners

You want to go for a run and know how speed and distance can aid your performance. Without heart rate, you can only get so far. The RS300X combines these three to give you a true understanding of the effort you put in. And on top, all the essential heart rate features come along RS300X, on the run and online.

  • Measures your heart rate combined with speed and distance
  • Helps you to train at the right intensity with personal training zones
  • Displays how many calories you’ve burned
  • Tracks your latest 16 training sessions and your last 16 weeks of training
  • Transfers training data to polarpersonaltrainer.com with optional Polar FlowLink™
